Why the two.0 and never the top-of-the-line Quadrifoglio? Good query.

The bottom and Ti Giulias use a 2.0-liter four-cylinder that places out 280 horses, 225 lower than the twin-turbo V6 within the Quad. It has 306 lb.-ft. of torque, 137 lb.-ft. much less. However the rear-wheel-drive 2.0 additionally weighs practically 300 kilos much less, is mechanically less complicated and sells for round $15,000 much less. In addition to the engine, lively aero elements and torque-vectoring rear differential, the two.0 and Quad use the identical well-balanced chassis.

The two.0 fashions got here in just a few trims with just a few totally different choices. Over the course of a virtually decade-long run–they usually’re nonetheless obtainable new–Giulias have modified little or no.

Which 2.0 would you like? Let’s begin with the drivetrain. Rear-wheel drive saves you 100 kilos over the all-wheel-drive model. Joe argues the advantages of an AWD exceeds the additional weight. “All-wheel-drive Audis are infamous for being understeer monsters,” Joe says. “Alfa Romeo’s is extra like BMW’s xDrive, the place it’s a rear-wheel-drive-biased system.”

Search for an Alfa with a mechanical limited-slip differential, too. “The vehicles with out the mechanical restricted rear slip completely eat rear brakes when pushed exhausting,” Joe says. “They’re consistently utilizing the rear ABS to simulate a restricted slip.”

One potential draw back to the mechanical limited-slip differential: It usually will get packaged with adaptive dampers. There’s even an additional button for the lively dampers on the DNA mode selector. “Should you’re in Dynamic mode and activate the dampers, the dampers truly get softer,” Joe says. “They took their cue from Ferrari–Ferrari calls it their ‘bumpy street button.’”

Two methods to repair this. One, you would get a automobile with no restricted slip and swap one in your self, like Centerline did, however discovering a restricted slip is tougher as of late. “We used to have the ability to purchase these in a crate from Mopar,” Joe says. “Now if you wish to order a mechanical restricted slip, they need a core again. A approach round that’s you would get a core from an Alfa-focused junkyard.”

The opposite method to keep away from these adaptive dampers is to search out an aftermarket answer. Fortuitously, that exists, with Joe recommending a coil-over package from KW that plugs in with out inflicting any critical ECU faults and works with the manufacturing unit lively features. He provides that KW additionally has manually adjustable coil-overs, too, for the Giulia.

Talking of ECUs, after mid-year 2018, the Giulia received a Safety Gateway (SGW). This makes the ECU read-only except you’re taking it to a dealership or use a plug-in aftermarket bypass. Whereas many Alfa Romeo dealerships are pleasant to the aftermarket, make sure to take away that earlier than any service at one.

Joe additionally recommends non-sunroof vehicles however admits they’re extremely uncommon. If headroom is a priority, don’t be too anxious, although. This 6-foot-4 driver with an extended torso has loads of room for his noggin’ with a sunroof.

When you’ve got an early Giulia with sport seats, these seats may not tilt. Fortuitously, Centerline has a package to make that occur.

The Repute and the Quirks

Italian vehicles are fickle, proper? Giulias have their points, some say. Joe concedes that Giulias did have some issues when first launched, however they’ve been largely resolved since then.

Issues to search for? Many high-pressure gasoline pumps would lose stress, particularly on scorching days. Some radiators leaked. Some oil pumps failed.

Talking of oil, Joe says it’s completely crucial on these vehicles. Change it commonly and use the oil made particularly for Alfas. “They’re delicate to grease due to the Multiair drivetrain,” Joe says. “It’s not a conventional twin overhead cam engine. It makes use of this Multiair brick to actuate the valves, and it has actually tiny oil passages in it. In the event that they get uncared for, they will have valvetrain points.”

The most important downside the media nailed Alfa Romeo on was {the electrical} system. The early Giulias shipped with Varta batteries producing insufficient voltage. Low voltage sends {the electrical} system into full tilt, producing all types of errors. Most vehicles by now have had their batteries changed, remedying this subject. Nonetheless, the Giulias don’t like low voltage. Joe recommends retaining the battery contemporary and says you need to by no means leap the automobile. No want for a flowery battery, although; Joe says a very good AGM battery will get the job finished. A lighter battery, Joe warns, may have an effect on the Giulia’s 50/50 weight steadiness.

If the automobile received’t begin attributable to a useless battery or critical electrical fault, there’s no method to put it into impartial from contained in the automobile to facilitate a tow. As an alternative, you should crawl beneath and use a software, reminiscent of one Centerline sells, that permits you to manually put the automobile into impartial.

As these vehicles grow old, watch the turbo’s wastegate actuator rod. With sufficient put on, the rod will begin to rattle and finally throw an underboost error code. Centerline will quickly be launching a brand new rod with bearings on the ends that may eradicate this downside for good.

Lastly, you can not merely flip off traction management on the four-cylinder fashions. A straightforward answer is to make use of an aftermarket tune that may alter when that traction management kicks in. “We’ve partnered with Eurocompulsion,” Joe says. “The traction management delete is inverse to the throttle opening. So, at low throttle opening, you could have a excessive degree of traction management. The upper the throttle opening, the extra it relaxes the traction management.”

For these actually bent on eliminating traction management, a extra excessive delete is out there. “What you are able to do is set up a DNA mode swap from a Quadrifoglio, which has Race mode,” Joe says. “Then you should do some pretty in-depth reprogramming to allow the swap. And since all Quadrifoglio fashions had adaptive dampers–that are tied into the assorted drive modes–there will probably be some errors with the Quadrifoglio DNA swap if the automobile doesn’t even have adaptive dampers. So, it’s not plug and play, however it may be finished.”

And reliability?

“We had that venture Giulia and bought it to a very good ex-employee,” Joe says. “He’s pushed it to 3 Alfa conventions, from right here in Colorado to the Higher Peninsula in Michigan to California to North Carolina. Should you keep them, they’re good.”

Need to Acquire Some Efficiency? Do This First.

As with most used automobile purchases, Joe recommends flushing and refilling all fluids. Should you’re doing any type of motorsport exercise, make sure to use performance-oriented brake fluid and brake pads.

It’s price noting that the Giulia is 100% brake by wire. That makes some brake upgrades not as noticeable. “We’ve a stainless-steel brake line package that replaces all of the flex traces,” Joe says, “nevertheless it doesn’t yield the advantage of a harder-feeling brake pedal.”

The Giulia and Stelvio share the identical brake rotors and calipers, bettering elements availability–to an extent. So far as track-oriented pads, Joe says they’re straightforward to search out for the entrance. The rear, not a lot. Eurocompulsion sells track-oriented rear pads from EBC.

Along with pads and fluid, Joe strongly recommends upgrading the wheel bolts to wheel studs, which makes taking off wheels a lot simpler and safer.

[Wheel studs: What you need to know before making the switch]

On Centerline’s venture rear-wheel-drive automobile, they went with a staggered wheel-and-tire setup to assist mitigate the traction management. Joe went with wider 19×9-inch wheels within the again and 19x8s up entrance. They slapped on some 225/40R19 rubber up entrance and 255/35R19 within the rear. To get the wheels flush, they went with 5mm wheel spacers in any respect 4 corners and put in rear fender extensions from a Quadrifoglio. “Collectively the staggered wheel-and-tire bundle and limited-slip differential yielded fast enhancements in straight-line traction and cornering grip, vastly decreasing annoying traction and stability management interference,” Joe says.

For many who want a sq. setup, Joe recommends a 19×9 setup with 255s throughout.

Need to go even wider? Joe says it’s potential. Go along with a 19×8.5 up entrance with 245 rubber and a 19×10 within the rear with 285 rubber. He says the automobile “will swallow it, no downside, as this was the manufacturing unit Quadrifoglio mannequin wheel and tire sizes.”

In relation to camber, it’s tough to get sufficient camber from the entrance, and also you’ll get truly an excessive amount of camber within the rear when reducing the suspension. Joe recommends utilizing modified decrease suspension arms for each entrance and rear, for various causes.

Reducing springs do exist, however Joe recommends coil-overs for critical autocross and observe use. Typically, Alfas profit from a bit softer experience than you’d encounter with a German automobile. “It’s the distinction between the roads in Italy and the roads in Germany,” Joe says. “Alfas at all times have been slightly softer, slightly extra physique roll, however they grip properly that approach.”

How In regards to the Energy?

The Giulia is a torquey automobile, with torque kicking in at 2000 rpm and growing linearly, Joe says. It doesn’t have a excessive redline, however efficiency enhancements that make the most of torque will profit the automobile, he provides. His three prime energy mods? Consumption, exhaust and ECU tune, which ought to value you round $2000, he says.

Seeking to go to an aftermarket cone-type consumption air filter? Watch out. “Alfa made it tough for tuners in that they’ve an consumption air velocity sensor,” Joe says. “By going to an aftermarket kind of filter, it might probably trigger the check-engine gentle to return on.” He provides that Eurocompulsion does have a few filter kits that don’t undergo from this subject, as they embrace a brand new, machined housing for the sensor.

Joe says many Alfisti complain that the Giulia is just too quiet, so it advantages from an aftermarket exhaust–however not simply from a sound side. “We’ve received a 3-inch cat-back from Magnaflow,” Joe says. “We up to date our unique exhaust design to make use of a Helmholtz resonator within the heart part in 2021–this offers the identical full-throttle sound but in addition eliminates drone within the 1800-rpm vary, with no impact on efficiency. You’ll undoubtedly really feel the throttle response distinction straight away with any primary exhaust. Most European producers go along with a 2-3/4-inch type of exhaust, however we’ve seen higher outcomes from a full 3 inches.”

Lastly, Joe recommends an ECU tune from Eurocompulsion referred to as the Euro+Drive system. “It simply installs by flashing the tune from a handheld gadget by means of the automobile’s OBDII port, and may be eliminated at any time,” he says. “It will increase energy and torque whereas retaining the complete performance of the manufacturing unit DNA drive mode settings.

“Our particular tune was a dual-mode tune, with Eurocompulsion’s Part I tuning put in within the N setting and their Part II tune put in within the D setting, with the A setting retaining manufacturing unit programming optimized for gasoline economic system,” provides Joe. “Our tune additionally included some optionally available options, reminiscent of stop-start system deactivation, Dynamic traction management and a rev-limiter improve to 6400 rpm. Total, the tune actually made the automobile come alive, pulling a lot more durable in all gears and permitting the automobile to rotate correctly by means of corners because of the extra relaxed traction management settings. In a really actual sense, the tune was what pulled the entire different modifications collectively and made them work as a cohesive bundle.”

Is This the Proper Automobile for You?

Joe believes the Alfa Romeo Giulia 2.0 platform gives a ton of potential if somebody needs to make the most of it, however it would require some trailblazing.

“The paths to take for a BMW 3 Collection or Audi A4 are well-known,” Joe says. “If you would like one thing totally different, the Alfa is a viable different. You’re not going to spend extra due to how Alfas have depreciated. A few of the mods could also be extra, however the automobile will probably be cheaper. It’s such a very good chassis that you simply don’t should tune the understeer out of it. You don’t should do a number of issues to have enjoyable with it.”
