On the lookout for a cool avenue automobile, classic racer or autocrosser that stands out from the GTI/Si/tii crowd? Wish to do it with some actual type? Then think about one among Alfa’s basic coupes, just like the 105-series Giulia.
There’s lots to suggest the Giulia (pronounced “Julia”). For one, there have been few automobiles within the early Nineteen Sixties that might be purchased for …
The Starting
The primary of the 105-series Alfa Romeos was a Giulia TI sedan, which rolled off the meeting line in Alfa Romeo’s newly-completed plant in Arese, Italy, in 1962. This new automobile actually did not look the a part of a sports activities sedan, nonetheless, with its boxy strains and upright cabin. Nonetheless, it was an actual sleeper and actually one of many first trendy sport sedans.
Below the angular, upright and reasonably staid (however aerodynamically environment friendly) sheet metallic of the Giulia Tl lay the muse of the Giulia coupe, which was launched a yr later on the Frankfurt Motor Present.
On the time of its introduction, the Giulia coupe was actually a scorching little quantity. A couple of traveler to Italy has been heard to remark that every little thing in Italy, from irons to rest room handles, appears to have a horny type to it; the brand new Alfa coupe was no exception. The place British roadsters had been usually cute however farm-tractor crude, and the rising BMWs had been dependable and well-built however conservative, the Alfa stood out as the proper mixture of sophistication, seems and efficiency.
The physique was styled by Bertone in Turin, Italy, and extra particularly by a younger designer at Bertone named Giorgio Giugiaro. By now, Giugiaro wants little introduction, having had an automotive design profession that has spanned 4 a long time and has produced among the most cherished and influential automotive design of our time.
The Giulia coupe was not Giugiaro’s first design for Alfa; he had additionally designed the 2600 Dash a few years prior. In designing the brand new coupe, he carried over many components of the 2600 Dash, together with inserting the headlights completely throughout the entrance grille.
The rounded profile of the small coupe is ra-rade way more so by the entrance and rear windshields, which seem to have been given simply as essential a job in styling because the sheet metallic. Having an aggressive lean to its entrance finish and a cockpit that’s comparatively far again offers the automobile a relaxed, but purposeful look. The design represented an actual departure from the type of the day; this prolonged to its very restrained use of moldings. The tasteful use of high quality chrome steel moldings surrounding the cockpit put the automobile in a category by itself.
Inside this fundamental physique type, the coupe mannequin vary encompassed 10 completely different fashions. Numerous fashions had completely different displacements, gas and induction methods, making for a dizzying array of fashions, however many of the main mechanical characteristics had been shared by all fashions within the vary. The next outlines the essential traits of the engine shared by most manufacturing fashions within the vary.
Below the Hood
The four-cylinder Alfa engine is without doubt one of the basic designs. It has loved one of many longest manufacturing runs of any engine for 2 good causes: It is powerful, and it really works. Whether or not in 1300cc, 1600cc, 17 50cc or 2000cc guise, the engine’s energy output has all the time compared favorably to that of its contemporaries, and even at this time it compares effectively to many four-valve, electronically-fuel-injected engines.
The engine’s oil pan, block and cylinder head are all solid in gentle alloy aluminum. The crankshaft is machined from cast metal, nitride hardened, and rides in 5 fundamental bearings. The connecting rods are cast from metal, the pistons from aluminum. Every piston rides in its personal separate cast-iron cylinder. The underside finish will stay a really very long time if commonly maintained.
The “moist” design of the engine signifies that every cylinder liner is totally surrounded by water. Alfa’s use of an aluminum block necessitated this design, nevertheless it does carry two benefits. The primary is that it offers even cooling, and the second is that the engines are infinitely rebuildable as a result of a cylinder worn too far to bore can merely get replaced.
However, as everyone knows, all of the unique specs on the decrease finish actually will not imply a lot if what caps all of it off is inefficient and antiquated. The Alfa’s cylinder head is what actually makes the facility; it’s also what defines the Alfa engine as a timeless basic.
Forged in aluminum, the twin-cam head is an eight-valve, cross-flow design, with the valves inclined at an 80-degree angle. This valve angle is necessitated by the twin-cam design and leaves a hemispherical combustion chamber. A centrally-located spark plug lights the combination–or, within the case of some fashions, two plugs are used.
Each the exhaust and consumption valves are actuated by way of bucket tappets and are adjusted utilizing shims; the exhaust valves are sodium-filled to assist dissipate warmth.
The cams are pushed off the crankshaft through a discount sprocket by a two-row chain, and so they run instantly within the head with no bearing inserts. As a result of gentle load on the cams, this usually causes no issues.
Most time-honored and well-known approaches to getting extra energy out of an engine’s backside finish apply to the Alfa engine. Excessivecompression pistons, boring, stroking, balancing and blueprinting all assist make a powerplant that’s highly effective, clean and dependable.
One modification that many skilled Alfa specialists make is to switch aluminum plugs which can be put in to plug machining entry holes. They drill and faucet the holes to simply accept an alien-head plug. The plugs tend to work themselves free over time, and after they fall out, it drops the oiI strain.
Modifications that may be made to the top embrace such fundamental approaches as milling it to extend compression, putting in hotter cams, porting and sharpening the consumption and exhaust passages to extend air move, and three angle valve jobs.
One of many best methods to get some extra energy and mileage out of your automobile could also be one of many easiest: retiming the cams. Advancing the consumption cam whereas retarding the exhaust cam can take advantage of the inertia that the exhaust fuel has developed on its rush out of the cylinder and permit the consumption valve to open just a little earlier, permitting the cylinders to fill higher at excessive rpm.
Wes Ingram of Seattle, Wash., has been constructing scorching Alfa engines for years. One merchandise in his bag of methods is to remachine the consumption manifolds on the SPICA system. He machines the manifold out to a constant 40mm all over and installs particular throttle shafts. This removes a taper that’s current, and Ingram has seen as much as a 10-horsepower achieve in modified engines. Principally, if it is a method of getting the air/gas in quicker and extra effectively, it must be addressed within the head.
The transmissions are all 5 speeds’, and they’re powerful, aside from a weak second-gear synchro. This weak synchro scenario can nonetheless final the lifetime of the automobile, and might simply be “crushed” by straightforward shifting.
One modification that may be executed, offered you do not occur to have that close-ratio Autodelta gearbox laying round, is to have a machine store drill and rebalance the gears. This each eases the load on the synchros and likewise permits for faster shifts.
The Mysterious SPICA System
The gas methods within the automobiles differ with every mannequin, however there are some fundamental developments. The carburetors on any given engine are usually a identified amount to most individuals, and any tuning specialist ought to be capable to assist out. As a result of most Giulia coupes provided on the market within the U.S. after 1969 are fuel-injected, it’s most likely extra essential to speak right here in regards to the much-maligned however poorly understood SPICA injection system.
Tailored from an present diesel design, the SPICA gas injection system was modified to work with gasoline in order that it might be fitted to the automobiles as a method of dealing with the tightening U.S. emissions legal guidelines within the late Nineteen Sixties.
Amongst specialists, the SPICA system is held in excessive esteem. Ric Lovecchio of RML Racing in Daytona Seaside, Fla., explains: “The SPICA automobiles had been and nonetheless are my favourite. The pump is so intriguing–it is an Italian masterpiece.”
Wes Ingram, who has rebuilt greater than 3000 of the pumps, holds them in such excessive regard that he contends that the mechanical perfection of the unit won’t ever be duplicated on any gadget fitted to a automobile.
Many specialists agree that many of the carburetor conversions that had been carried out to treatment working issues attributed to the SPICA system had been pointless; both the issues weren’t the fault of the SPICA system, or they had been simply correctable.
“Becoming carbs to a automobile that was injected is extra of a compromise than a repair,” says Ingram. He additionally says that individuals usually equate the static throttle response of the Webers with extra energy. “You simply cannot beat the SPICA system for throttle response beneath load,” he says.
One other drawback that centered across the SPICA system was as a consequence of the truth that the system was thought-about to be an emissions-control gadget. To stop tampering with this so-called emissions-control gadget, Alfa didn’t permit sellers to work on the pumps, and elements weren’t out there. Handily, although, Alfa would change pumps regarded as faulty. This hands-off coverage, coupled with the truth that Alfa was the one firm to make use of this method, helped to deepen the thriller surrounding SPICA gas injection.
The SPICA pump operates like a miniature four-cylinder engine. The “crankshaft” contained in the pump is pushed by a cogged belt that runs off the engine’s personal crankshaft, and appears extra like a camshaft. Its “pistons” are plungers that journey up and down of their bores, compressing the gas so {that a} pressurized pulse opens the injector and sprays gas into the consumption path.
A setup this straightforward is simply in a position to ship the identical quantity of gas, no matter working circumstances, however by way of a sequence of mechanical logic changes for load, temperature, throttle place, and engine pace, the system compensates reasonably effectively.
Some of the frequent issues with the system, based on Ingram, is brought on by the phase-out of leaded gas on this nation. The lead within the gas helped to lubricate the plunger and barrel partitions, stopping put on. The plunger and barrels are now not out there, so when he rebuild a pump, Ingram custom-matches his remanufactured plungers to barrels of the suitable measurement.
One other drawback happens not within the pump itself, however within the thermostatic actuator that controls heatup. These actuators can change into lazy over time and trigger a variety of beginning and working issues.
If you’re making efficiency modifications to the Alfa engine, the SPICA pump also needs to be modified to permit for the engine’s elevated demand for gas. As this bigger gas demand is just not merely a linear change, the 3D cam within the logic part of the pump should be reshaped to accommodate it. This offers the engine extra gas precisely the place it wants it.
In line with some fans, nonetheless, this modification might end in burned pistons and valves. When utilizing a modified pump, Ingram additionally recommends utilizing an oxygen sensor and an air/gas combination gauge to assist monitor working circumstances. Recalibrating the pump may also add some benefit, because the manufacturing unit tolerances tended to be just a little beneficiant. Ingram has seen engines understand good points of as much as 10 horsepower after a easy recalibration of the pump to extra exact tolerances.
Using Down the Highway
The entrance suspension is a built-up sort of double A-arm setup, with the underside arm being constructed round a spring pan, and the highest arm comprised of a transverse hyperlink and a longitudinal hyperlink that gives caster adjustment. The entrance finish is sprung by coil springs and is damped by a traditional shock absorber; a traditional anti-roll bar is used to restrict physique roll.
Autodelta was the manufacturing unit’s racing arm beginning within the mid-’60s, and so they pioneered many efficiency modifications for the coupes. A kind of was used within the entrance suspension to change the higher transverse hyperlink of the suspension to supply some adjustment for adverse camber. All the standard guidelines apply concerning set up of stiffer springs and shocks.
One other in style modification is to make use of spacers between the spring pans. This lowers the entrance finish of the automobile with out altering the spring charge. Lovecchio says that even with out altering springs and shocks, however by giving the automobile just a little reverse caster with just a little toe out, one can dramatically enhance dealing with.
Surprisingly, given the extent of sophistication of the remainder of the automobile, the rear suspension employs a tried-but-true live-axle system. Because the inherent drawback with any stay axle is controlling lateral motion, Alfa engineers designed in an answer that labored reasonably effectively.
This answer was a cast-iron, T-shaped bar that mounts between the differential casing and the rear body rails within the physique. This permits the axle to maneuver up and down, however does an excellent job of eliminating lateral motion.
As well as, the axle is situated by two stamped-steel radius arms that pivot forward of the axle. These arms are mounted within the physique by rubber bushings. Just like the entrance finish, the rear of the automobile is sprung by coil springs and standard shock absorbers. Roll is managed by a traditional anti-roll bar with drop hyperlinks.
A modification that Autodelta made, and that many racers have copied, includes deleting the Tbar and as a substitute mounting blocks on the differential and physique that information the axle and restrict its lateral motion. This association additionally lowers the roll middle of the automobile and locates the axle in addition to or higher than the T-bar system–however the draw back is that it’s mentioned to bind throughout lateral masses.
One other modification to maintain the rear axle in place is using a Panhard rod which, just like the sliding block, lowers the roll middle and likewise retains the rear in line.
Simply as on the entrance finish, a much bigger anti-roll bar within the rear will assist restrict physique roll. Artful racers imitate a GTA mod: On these automobiles, the anti-roll bar mounting was moved from above the rear axle to mount on the rear of the ground pan. The top hyperlinks choose up on the radius arms.
The Giulia coupe additionally got here normal with four-wheel, vacuum-assisted disc brakes, with the hand brake integrated into the internal a part of the rear disc. Automobiles had Dunlop brakes till 1967; after that, due to this method’s want for frequent changes, later automobiles had been switched to a system manufactured by ATE.
Physique Construction
The Giulia coupe was, in lots of respects, overbuilt: at a time when many automobiles had been nonetheless constructed utilizing a separate body and physique, the 105-series Alfa was among the many few that used a totally unitized physique development.
The match and end of the automobile’s coachwork had been second to none. Whereas many manufacturers of appreciable reputation had been nonetheless counting on lead-loading of panel gaps to realize acceptable match, the Alfa used no lead, and every little thing match simply tremendous with out it. As well as, to scale back price, different producers had been designing automobiles to make use of bolt-on entrance fenders to avoid wasting labor of their “Carrosseries.” On the Alfa, your fingers can hint a line, uninterrupted by panel gaps or seen seams, backward and forward in addition to from entrance to again on the automobile. Do that with nearly any automobile at this time, and see if you are able to do it. This way of physique constructing was nearly completely the area of different European marques, similar to Porsche and Mercedes, that had been way more costly than the Alfa.
Below the pores and skin, the standard of the Alfa’s development continues to indicate. Whereas most of the automobile’s contemporaries used separate, bolt-in subframes to hold the working gear, the Alfa was designed utilizing a boxed subframe that was welded to the 2 entrance body rails. These body rails tie the entrance of the automobile to the firewall and to the ground. They’re very robust, being basically a built-up channel part of thick metal. They run from behind the entrance bumper to beneath the entrance seats.
Putting in an efficient roll cage is without doubt one of the greatest methods to strengthen the physique shell. The important thing right here is to be sure that the cage picks up as shut as attainable to suspension mounting factors. If correctly put in, it will dramatically enhance dealing with because it stiffens the chassis.
Racing within the ‘60s and ‘70s
The Alfa Giulia in all its types and guises was developed right into a formidable race automobile for a few years. Competing each within the U.S. and in Europe, the Giulia loved appreciable success in touring automobile racing. Though the automobiles had been usually not pushed by internationally-recognized, big-name drivers of the period, the Giulia coupe nonetheless racked up spectacular numbers throughout Europe within the hand of drivers similar to Andrea DeAdamich, Toine Hezemans and others.
From the mid-’60s to the late-’70s, the GTAs had been supreme of their class and winners throughout Europe and the world. Lots of of sophistication and particular person race wins culminated in Alfa successful the European Touring Automotive Championship for the 1300cc and 1600cc courses in 1968.
Within the U.S., the Giulia coupe discovered the proper alternative within the Trans-Am racing sequence that was began in 1966. Initially known as the Trans-American Sedan Championship, the sequence consisted of highway races at tracks throughout the nation, with every occasion contributing factors to a producer’s championship. The automobiles contesting the TransAm sequence had been primarily based on FIA Teams 1 and a couple of, which carefully resembled the B Sedan group of the SCCA.
The foundations had been the hallmark of the Trans-Am sequence. A automobile’s final race weight was determined by the design of its engine; every automobile was assigned a sure weight/cc ratio primarily based on its engine design. The Alfa was slated to weigh 1.2 kilos per cc; a automobile such because the Datsun 510, which had a non-crossflow SOHC engine, needed to weigh in at 1.1 kilos per cc. Theoretically, this equalized the automobiles, though because the sequence progressed, the cash poured into growth was to be the deciding issue.
The inaugural Trans-Am sequence race came about in Sebring on March 25, L966. The Alfa discovered itself working alongside bigger displacement American automobiles, however the total victory however went to Jochen Rindt, driving a GTA. Different GTAs positioned third, fourth and fifth within the race, firmly establishing Alfa’s presence in American sedan racing.
Though the V8-engined American automobiles and the smaller, under-two-liter European automobiles had been classed individually, they initially ran collectively. Additional growth of the American muscle automobiles noticed the pace differentials of the 2 courses enhance to the purpose the place it was unsafe, nonetheless, so in November of 1969 the sequence was divided into two elements. The smallerbore automobiles had been allowed to sport engines as much as 2.5 liters in displacement, and this sequence was named the Two-5 Problem. The concept was that this is able to permit automobiles with barely largeger engines to compete; none ever did.
Though the foundations modified from yr to yr, the fundamentals remained the identical, permitting for some consistency and for automobiles to maintain competing yr after yr. Regardless of weight handicaps and an absence of main manufacturing unit help, within the arms of drivers Horst Kwech, Gaston Andrey and Bert Everett, the Alfas made for fierce competitors towards the BMW 2002s and Datsun 510s. The automobiles had additionally been developed to an almost bulletproof 200 horsepower, and Alfa was in a position to seize the championships in 1970.
They’d have received in 1971, too, however the successful automobile of Horst Kwech was disqualified after post-race scrutineering revealed that the automobile’s gas tank held 17 gallons, whereas the foundations known as for a 15-gallon most. The victory was given to second place and the BRE-prepared Datsun of John Morton.
As Classic Racers
Paul Spruell, of Paul Spruell Alfa Romeo close to Atlanta, has been racing Alfas since they had been new, successful a number of SCCA nationwide championships alongside the best way. He at the moment classic races a GTA, nevertheless it’s not simply any run-of-the-mill automobile–it is Horst Kwech’s ex-Trans-Am racer.
Spruell ‘s restoration of the automobile was initially confined to a beauty refreshening, however over the course of its racing profession this morphed into a whole restoration as practically every little thing on the automobile was rebuilt or changed. He famous that any issues he encountered weren’t betrigger the Alfa is not a really powerful automobile, however as a result of this race automobile was practically 35 years previous.
That sentiment is echoed by John McKaig of Alfas Limitless in Norfolk, Conn. John says that the important thing to getting ready a classic race automobile is simply that-preparation. All the things should be proper, or the weakest a part of the system will let the automobile down, whether or not it’s a radiator hose that’s previous its helpful life, or a gas line that has change into cracked from the engine torquing over and tugging on it.
“Folks usually overlook the small issues, as a result of they don’t seem to be so simply seen,” he says. “I’ve gotten into the observe of tugging and pulling on issues beneath the automobile, as a result of it forces you to pay extra consideration to the small issues, and it will possibly warn you to potential issues earlier than they change into failures.”
Many classic golf equipment throughout the U.S. permit the Giulia to compete in a single kind or one other. Many permit updating to the two-liter engine, which presents no issues as all of the mounts are the identical. Brakes could be up to date, and most of the modifications made to the manufacturing unit race automobiles could be executed by the expert fanatic.
Clearly, for those who’re planning on classic racing one among these automobiles, you should test with the sanctioning physique you propose to run with to see what years are eligible and what modifications are permissible. Additionally, your probabilities at competing in one of many extra elective classic racing golf equipment enhance for those who can again up your automobile’s provenance with an previous logbook proving that the automobile was as soon as pushed competitively.
Mechanical Checks
Now you can buy an Alfa Giulia coupe–a automobile that was fairly costly when it was new–for comparatively much less at this time. Any analysis of the automobile’s mechanical situation ought to observe the identical commonsense method you’ll use when shopping for any used automobile. Nonetheless, sure areas do warrant further consideration.
The automobiles are usually strong, however easily-correctable issues can snowball into a complete host of points. One engine drawback that’s frequent sufficient to warrant consideration is the sudden lack of oil strain. This clearly could be brought on by a wide range of culprits, similar to a nasty oil, pump, however within the Alfa it will possibly additionally occur for one more motive: The crankshaft has aluminum plugs which can be hammered in to plug holes that remained after the oil passages had been machined. Typically one among these falls out, and might trigger an roughly 10-psi drop in oil strain.
One other frequent drawback is blown head gaskets. The Alfa’s gaskets fail in all of the ways in which regular head gaskets fail, however they appear to take action with higher regularity. A typical mode of failure is leaking oil into coolant and vice-versa. This occurs when the o-rings that seal the oil passage between the top and block fail.
A simple test for a nasty head gasket is to tug the radiator cap and test for oil floating within the coolant. When you see coolant within the oil (or oil within the coolant), it almost definitely equals a blown head gasket. Additionally, pull the dipstick: If emulsified coolant exhibits, this implies bother, as main injury to the engine bearings might have resulted from coolant being pumped by way of the oil system.
The SPICA system is a thriller to most individuals, because it solely got here on Alfas. Some frequent signs of a maladjusted pump embrace poor gas mileage, onerous beginning and wealthy working.
Additionally test the metallic gas strains that run beneath the automobile. They had been lined with insulating foam from the manufacturing unit, and whereas this may increasingly have stuffed some goal years in the past, extra usually it solely helps to entice water subsequent to the strains, hastening their corrosion.
One other notoriously weak level on Alfa coupes is {the electrical} system. Since electrical glitches could be each time-consuming and costly to hint, it is very important word what basic situation it’s in. Search for so-called “fixes” that prior homeowners or mechanics have executed.
Elements Availability
Fortunately, elements availability for the Giulia coupe is comparatively good by way of mechanical elements the typical fanatic would wish. Nick Sorensen at Centerline Alfa Romeo Elements in Boulder, Colo., says most mechanical restoration and upkeep elements are available. save for the actually odd request similar to a rear axle. Their catalog displays this good availability.
Physique and trim elements, nonetheless, aren’t really easy to come back by and are additionally not low cost. For the particular person caught with a rusty automobile, nonetheless, there are numerous vital elements out there to resurrect the shell.
Matthew and Vicki Jones of Re-Originals in Houston, Texas. have many structural and outer sheet metallic panels out there for the Giulia coupe. Re-O1iginals additionally shares an intensive line of replica inside and trim elements, lots of that are remanufactured by the unique suppliers to Alfa in Italy. Important sections out there embrace all rocker panels and ground sections. Additionally out there are restore sections for the entrance and rear fenders that comprise the entrance and rear sections of the rocker panel. Full nostril panels are additionally out there, though acceptable rust restore panels for the decrease edge aren’t but out there. Availability of elements is simply getting higher, based on Matthew Jones, as entrance and rear fenders will likely be out there quickly.
All physique gaskets can be found, and Jones says they’re of higher high quality than the originals as a result of the rubber know-how is best at this time than it was 30 years in the past.
Arduous-to-find Elements
Fuel tanks are now not out there, though some NOS tanks do sometimes come in the marketplace. As a result of many house owners of late U.S. automobiles have eliminated the glue-in glass and retrofitted a rubber gasket-style windshield, the aluminum moldings for the rubber gasket-style entrance glass are extinct, too. Jones expects them to be out there someday this yr, although.
A lot of the smaller moldings on the cai·s are additionally not out there, however as they’re product of chrome steel and don’t tarnish, boring or rust, acceptable ones could be cannibalized from elements automobiles.
Giulia Coupe Manufacturing Fashions
1600 Dash GT (mannequin 105.02), 1965 – ’72
Introduced in 1963, this was the primary of the 105-seiies coupes. With a 1600cc engine and two 40mm sidedraft Webers, it produced 106 horsepower.
As with all automobile mannequin that lives an extended life, this authentic mannequin is taken into account by many to be the most effective. The early automobiles had the cleanest exterior styling and the only interiors.
1300 GT Junior (mannequin 105.30), 1966 – ‘72
The 1300cc model of the Giulia coupe was launched in 1966 as Alfa’s entry-level mannequin coupe. It featured smaller consumption ports and 40mm DCOE Weber carburetors, but it wasn’t in any respect asthmatic, nonetheless making practically as a lot torque because the 1600cc Dash GT The automobile was able to 100mph. The Junior additionally had a entrance grille with a single bar as a substitute of the eight-bar grille of the 1600.
1600 GTV (mannequin 105.36), 1965 – ’68
The “veloce” model of the Dash had a small enhance in energy from the 1600cc Dash GT, however most notably a fatter torque curve. A fast method of differentiating the GTV from its GT Dash brother is the grille that had solely three slats.
1750 GTV (mannequin 105.51), 1969 – ’11
With the mannequin title 1750 evoking photographs of Alfa’s racing automobiles of the Nineteen Thirties, the 1750 GTY was launched in Europe in 1968. One yr later, it grew to become out there within the U.S. after Alfa engineers handled some last-minute adjustments to the fuel-injection. The introduction marked the primary time that the European and American mannequin automobiles had been markedly completely different.
Largely the identical because the automobiles that preceded it, the 1750 featured 80mm bores, up from the 1600’s 78mm, whereas the stroke of the engine was elevated to 88.5mm, a rise of 6.5mm from the 1600. This led to horsepower good points of about 10 to fifteen horsepower over the 1600.
Exterior variations included the entrance fringe of the hood becoming flush with the nostril and the entrance parking lights not being included within the entrance fenders. The bumpers additionally sprouted small bumperettes.
As is typical of a maturing mannequin line, the 1750 additionally began turning into rather less Spartan than its 1600cc predecessors. The outside went to 4 headlights and a flush-fit hood within the entrance. The taillights additionally grew barely bigger.
2000 GTV (mannequin 115.01), 1972 – ’74
The 2000 GTV was the fruits of the Giulia coupe. Because the final of the road, it featured the most important engine capability, essentially the most energy, and essentially the most refinements. Bought within the U.S. from 1972-’74, that is by far the most typical of the Giulia coupes now out there.
The step up in engine measurement to a full two liters (1962cc) was accompanied by an increase in energy as effectively. The engine went from roughly 122 horsepower within the 1750 to 130 within the 2000. Extra notable was the rise in mid-range torque. A restrictedslip rear finish grew to become normal on the 2000 GTY, and brakes had been as soon as once more enlarged to accommodate the rise in energy.
There have been extra styling adjustments, too, largely within the entrance finish. The grille now not had the daring Alfa Romeo defend standing proudly between the headlights, because it was now a raised section of the grille slats.
Many purists decry the final GTV mannequin within the line as a tarted-up model of the Spartan authentic, however think about this: a minimum of the GTV by no means succumbed to 5 mph bumpers, as did many German and British automobiles.
Giulia Coupe Manufacturing facility Sizzling Rods
The Giulia coupe boasted such a tremendous pedigree, it was solely pure that the manufacturing unit would use them as a foundation for creating out-and-out race automobiles–and so they did.
GTA (mannequin 105.32), 1965 – ’69
Homologated for European touring automobile racing in 1965 by Autodelta, the 1600cc Giulia GTA is essentially the most fascinating of the Giulia coupes.
The “A” in GTA stands for “Alleggerita,” which implies “lightened.” Lightening the automobile was achieved by way of all-aluminum outer physique panels, plastic facet home windows, alloy wheels and a naked inside. This saved practically 500 kilos from the manufacturing Dash GT.
The aluminum physique panels had been riveted onto a manufacturing ground pan and construction. An actual GTA is definitely identifiable by the visibility of the rivets wherever the outer panels are mounted to the automobile’s metal construction. One straightforward spot to test is the drip rail, the place the bent rivet heads are seen.
To make the light-weight coupe rise up and go, Alfa fitted an extensively modified engine. The cylinder head was modified to simply accept two plugs per cylinder, a better compression ratio was used, an engine oil cooler was added, and a pair of fire-breathing 45 DCOE Webers jutted from the manifold.
Apparently sufficient, the 1600cc GTA head had smaller consumption ports than its road-going brother. In racing kind, the engine produced 170 horsepower, up from the usual automobile’s 106. Transmissions had been additionally light-weight, close-ratio items.
Suspension modifications made to the GTA included utilizing the sliding block rear finish, a remounted rear anti-roll bar, and alterready entrance finish geometry.
GTA Junior (mannequin 105.59), 1968 – ’72
To spherical out Alfa’s racing arsenal in 1968, and to permit them to contest different courses within the European Touring Automotive Championship, Autodelta homologated a 1300cc model of the GTA. Based mostly on the 1600cc GTA platform, it bought a equally hotted-up model of the 1300cc engine and was known as the GTA 1300 Junior, or GTAJ.
Apparently sufficient, 100 of the GTA Juniors had been outfitted with the identical SPICA gas injection system fitted to U.S. automobiles, pf-of {that a} so-called “emissions management gadget” could be put to efficient use.
GTAm, 1970 – ’71
The GTAm was one other competitors model that got here in two flavors: a 1750 and a 2000. Both method, the automobile was constructed to U.S. specifications, that includes SPIC A gas injection. The GTAm regarded an identical to a inventory 1750 or 2000 GTV, however a buyer might order vast fender flares and a bunch of different goodies to convey the automobile as much as Group 2 racing specs. Though homologation necessities specified that 1000 items be produced, solely 40 GTAms had been produced in full racing trim.
One very fascinating departure from Alfa custom was the GTAm’s use of a monosleeve engine, with all 4 cylinder inserts solid as one unit.
GTA SA, 1967- ’68
The GTA SA was a supercharged variant of the usual 1600cc GTA. It was a powerhouse, producing 220 horsepower. It was constructed to Group 6 prototype specs to compete towards closely modified BMWs and Lotus Cortinas. It was the one supercharged automobile to contest the European Touring Automotive Championship.
The supercharging system on the GTA SA was-quite distinctive. The superchargers had been sourced f om plane cabin blowers that had been made by Fiat. They had been spun by high-pressure oil that got here from an oil pump mounted on the engine’s timing cowl; fairly an ingenious use of followers.
Physique Analysis
The place to test for rust on an early Alfa coupe? In every single place. Now, after all that is true for nearly any automobile that is pushing 30 years previous, nevertheless it’s very true for Alfas.
Your analysis of the physique needs to be the one greatest figuring out issue as as to if or not you purchase the automobile. Fixing a rotten shell is just not solely time-consuming, however it’s prohibitively costly for a automobile like this that may nonetheless be present in comparatively rust-free situation.
The common fanatic could also be fairly adept at mechanical work, however the cash, metallic fabrication and bodywork expertise required to return a rusty shell to its former glory are often past the expertise, budget and endurance of all however essentially the most diehard rustheads. With that warning, here’s a information to inspecting the physique of the automobile.
This is the brief model: Search for accident injury, proof of earlier “restoration,” manufacturing unit spot welds, and even panel gaps. Examine wherever metallic is lapped collectively and/or spot welded, ensuring the joint is just not bulging with rust. A extra concerned test, nonetheless, isn’t a nasty concept.
What to convey: skepticism, a ground jack, jack stands, an excellent flashlight, and most of all, a pointy axe or small screwdriver. If an proprietor takes offense that you just need to poke and prod his delight and pleasure, reassure rum that you just will not jab the paint, and that poking stable metallic would not actually damage it anyway. Additionally, guarantee him that you’ve money in pocket to purchase the automobile if he balks at letting you jack it up; this could ease the scenario.
What to depart behind: your feelings and your pal who labored at a physique store for a summer time 10 years in the past and nonetheless thinks he is aware of all of it.
Now, do not even take a look at the paint. New paint has a singular skill to look nice whether or not it’s sprayed over plastic filler or over metallic.
The Giulia rots in all places, so the simplest factor to do is to start out wanting on the outer bodywork. Examine panel match: Is it usually even? Do not be fooled by some pseudo know-it-all who assures you that the panel match was by no means good on these automobiles. Panel match was very constant, and superb. Keep in mind, it’s not a British automobile (with apologies).
Examine the rocker panels. They’re a particularly vulnerable a part of the automobile, and so they present a whole lot of info with only a look, if you realize what to search for.
The one a part of the rocker panel that’s seen is straight away beneath the door. They’ve a vertical seam that runs with the vertical door gaps. This vertical seam is the place the rocker disappears behind the decrease portion of the entrance fender and rear quarter panel. These seams are in regards to the first place to rust on these automobiles; they’re additionally troublesome to restore correctly and are subsequently often the largest giveaway that repairs have been executed.
It’s also a good suggestion to examine the 2 jacking factors situated alongside the rocker panels, as they rust shortly as effectively. They’ll cave into the rocker panel if the automobile was jacked right here whereas the rocker was rusted. There are two on either side, one entrance and one again.
Now examine the rear wheel arches. The best way the quarter panel is welded to the internal fender makes a really perfect ledge for mud to gather, hastening rust. On a pleasant authentic automobile, there needs to be small, seen spot-weld dimples that run the entire perimeter of the arch. Run your hand alongside the internal edge, feeling whether it is fatter than two skinny sheets of metallic. Whether it is, it’s most likely both in want of restore or has been re- paired. Be careful for metallic slivers, although.
Look across the entrance and rear home windows, because the automobiles are liable to rust right here, too, probabIy as a result of putting in the windshield scratches the paint. 1972 and later GTVs have glued-in windshields, which appears to have made the issue worse. It’s attainable and fascinating to retrofit an earlier rubber seal for those who additionally substitute the windshield and acquire the rubber-type moldings.
Additionally look across the rear-most a part of the rear quarter home windows, because the automobiles are infamous for rust right here. That is very difficult and time-consuming to repair correctly, so test it effectively by pulling the seal away so far as you possibly can and searching for rust that won’t have began creeping into sight.
Examine the door bottoms. ls the within edge the place the pores and skin wraps across the shell straight and crisp? Does. the seam appear to be it’s about to blow other than the rust?
Now that you have regarded on the cosmetics, it is time to transfer on to the meat and potatoes. Actual racers need true structural integrity.
Jack up the entrance of the automobile, and help it effectively on the body rails, in the event that they nonetheless exist. Now take a look at the bottom portion of the rocker panels the place they wrap round and are spot welded to the internal rocker assemblies. The spot welds needs to be about pea-sized and spaced about an inch aside, working the complete size of the rocker. The identical welds needs to be seen on the decrease entrance fenders and quarter panels in addition to the place they wrap across the rocker panels.
Take a look at the decrease a part of the outer nostril panel, the place it wraps across the internal cross member. Is the sting of the panel crisp? Does it have bulletformed drain holes working alongside the sting? ls the sting bulging from the rust that’s constructed up behind it? Word the foremost mounts for the entrance anti-roll bar. Do they appear unusually out of whack? (They’re alleged to be straight.) Do they exhibit indicators of stress? It is a high-stress space clue to the mounting of the anti-roll bar. Now, look across the again facet of die inner cross member beneath the radiator, simply forward of the place the anti-roll bar runs. That is susceptible to rust for a number of causes, the chief being poor drainage. The second reason for rust is’ the truth that the radiator lies above. Poke this space together with your screwdriver at a number of factors. Does it really feel smooth?
Look within the engine bay. Rust is usually not an excessive amount of of a difficulty right here, as die panels are comparatively ve1tical, and they don’t seem to be product of boxed sections. Nonetheless, the important thing right here is to search for proof of crash injury that has not been mounted. Search for metallic that appears unnaturally wrinkled or bent. Take a look at die seams the place die outer fenders weld to die internal fenders. Are they crisp? Are you able to see the manufacturing unit spot welds within the entrance a part of the drain by way of?
The all-important body rails are welded to the decrease a part of the internal fenders, however are usually not a rust drawback right here–wait till we transfer farther again and beneath the automobile.
Examine the spare tire effectively. It ought to have a big domed hump within the center, and if it isn’t there, search for proof of restore. There also needs to be a small rubber drain right here, which is a perfect spot for rust to start out.
You also needs to test the fuel tank while you’re right here. The tank is liable to rust as a result of if the trunk leaks, the water sits proper across the welded seam that holds collectively the highest and backside halves of the tank. Though it’s attainable to repair a rotten tank, new ones aren’t out there, although it’s attainable to retrofit a later tank.
Now, assuming you truly had body rails to help the automobile on, take a look at them. Are they bent? They don’t seem to be precisely the identical backward and forward. however they need to be comparatively straight. Search for proof of their being pushed upwards into the ground, as a result of this often solely occurs in a single instance-when the ground is rotted.
Transfer on to the ground pan. The ground pan is product of three sections: the transmission tunnel and two halves (left and proper). Drainage holes situated within the ground pan give rust a toehold simply on. Take a look at the entrance part of the ground, ideally the driving force’s facet, as it’s particularly susceptible. There needs to be a drain gap close to the outer entrance portion of the pan, roughly beneath the clutch pedal, and it ought to have an roughly three-inch rubber plug in it. Examine across the plug. There needs to be no seams on this a part of the pan; if there are, it signifies that earlier repairs have been carried out.
Now take a look at the strengthening cross members that run laterally beneath the 2 seats. To begin with, are they even there? Second of all, one a few instances with the screwdriver to evaluate its situation.
Take a look at the rear part of the ground. Two extra rubber drain plugs are situated right here and–you guessed it–they’re one other potential rust space. Take a look at the very rear-most part of the ground, the place it’s spot welded to the rear bulkhead panel. That is essential as a result of the radius arms for the rear suspension are tied in right here.
While you’re beneath the automobile, take a look at the internal rocker panels. If in case you have even gotten this far with out giving up, take coronary heart, as a result of they’re most likely tremendous. This panel is product of surprisingly thick metallic in comparison with the remainder of the automobile and could be very stout. Nonetheless, simply to make certain, give it a few good jabs alongside its size.
Most individuals would reasonably forgo sandblasting, grinding and welding in favor of putting in large anti-roll bars and scorching engines, so be sure you consider the physique very rigorously.
The Alfa Giulia coupe, with efficiency that belies its age, could make a superb avenue performer or a potent classic race automobile. It’s well-engineered and classy, and there’s a giant community of elements, service and restoration help. Mix all these pluses with Italian type and sexiness, and you have an actual winner.
