Giulia Tuning

"Thank you for reading my Giulia tuning guide."

Powertrain choices comprised 2 petrol versions, the 2.9 L F154 twin-turbocharged V6 and 2.0 L GME T4 Multiair turbocharged  and Diesel in the form of the 2.2 L JTDm I4.

All offer great reward when tuned, and handle really well, especially with a few choice suspension tweaks and upgrades.

We review and look at Giulia tuning and show the ultimate modifications. Alfa Romeo Giulias have loads of potential and with a few sensible performance modifications you can substantially maximise your driving pleasure and just add some more polish to a really good and well put together car.

You can do a lot to improve the performance of your Giulia with our step by step tuning tips. The key to Giulia tuning is doing it right - a lot of money can be wasted if you do it wrong.

Our aim in Giulia engine tuning should be to increase peak power and Torque at the top end.

Smaller engines do not provide much of a return in terms of power so start with a bigger engine. Engine swaps are a good option if you have a small engine size.

Power mods.

These are the modified upgrades are usually carried out by our members, decide how far you want to go before you get going.

Getting the correct grade of uprated modifications for your planned usage of the car is a time and money saver. Stage 3 motor sport parts just won't work well on the road making the car difficult to drive.

Best mods for your Giulia

1. Lightened Flywheels - a lower mass flywheel will improve the engines free revving nature. Not always beneficial for all Giulia engines.
2. Brake Mods - Enhancing your stopping power ought to be listed in your priority list.
3. Upgrades to turbochargers and superchargers - Adding a turbocharger is the most significant way to increase air supply, which permits you to use more fuel and make higher power. Typically one of the most complex modifications you'll see massive gains.
4. Internal engine mods - crank, pistons, conrods & compression ratio including balancing and blueprinting
5. Giulia Suspension - Fitting a more sporty Suspension kit greatly enhances your Giulia road holding and cornering. Adjustable coilovers and better bushings are what is needed here.
6. ECU Tunes - A Remapped Giulia ECU ensures the most power in terms of your investment, aftermarket ECUs, and inline Tuning boxes are all alternatives.
7. Air Intake and Sports Exhausts - Be aware on their own these mods won't ADD HP on most cars, but they will enable you to lift power after other modifications by lessening the restrictive flow.
8. Fast road Camshafts are generally the biggest mechanical mod upgrade, but should always be setup by someone qualified to set them up properly and they are not always easy to source but we are sure you'l; find a local firm to regrind a stock camshaft for you.

Giulia Tuning Stages

Typical stage 1 mods often include: Sports exhaust, Suspension upgrade (drop 30-40mm), Engine Tunes/Remapping, Alloy wheels, Lighter flywheel, Panel air filter.

Typical stage 2 mods often include: Ported and polished head, Fast road cam, high flow fuel injector, Power/Sport clutch, fuel pump upgrades.

Typical stage 3 mods often include: Sports gearbox, Internal engine upgrades (pistons/head/valves), Adding or upgrading forced induction (turbo/supercharger), Competition cam, Engine balancing.

You should keep as much low end torque as you can and aim for a wide power band rather than a narrow top end power spike.

The whole point of our articles is to give a limited introduction of tuning mods and point you in the right direction, our forum is the place to go for detailed advice and tips on your tuning project, the best tuning upgrades and all aspects of modding cars.One of the best mechanical tuning upgrades you can do to your NA (naturally aspirated) engine is to fit a fast road camshaft .

The intake and exhaust durations play a large part in your cars power band, but be careful here, getting this wrong can upset the idle and make the car difficult to drive in traffic. You'd need to follow a camshaft upgrade with other mods and finish with a tune/remap for the best performance gains.Don't forget to look at the fuelling when you are increasing the power - it makes the car more thirsty.

Using high octane fuel is another option if you find you are suffering from pinking or premature ignition on your Alfa Romeo project after fitting other modified kits. Uprated injectors will enable you to supply sufficient fuel to the engine. Uprate the fuel pump to cope with the extra fuel requirements of your tuned Giulias uprated injectors.

Giulia Intake and Exhaust Tuning.

Now we move on to the intake and exhaust and ensure proper flow through the engine. Please note that WE DO NOT RECOMMEND INDUCTION KITS, unless you have tuned your car extensively and are finding that the standard air intake has become a restriction. For most Giulia engines TorqueCars would suggest you just go with a washable panel air filter. On heavily tuned engines and turbo vehicles an induction kit will help release the power providing you address the problem of needing cold air.

Sports exhausts can help equal out the flow of gases through the engine. But if the exhaust is too big, ie: over 2.5 inches bore, you will lose a lot of the exhaust flow rate and end up losing power and torque.

Head work including a polish and port and 3 or 5 angle valve job will really help to release the potential of the engine. In nearly all cases of Giulia tuning your clutch will start to complain and this needs to be uprated - read our overview on clutches for more information. Turbo engines are just crying out to be Reprogrammed. You will see big power gains on most modern turbo charged cars including diesels making a tune/remap one of the most cost effective and big modifications for your money.

We've also seen some tuners playing with twincharged conversions and making some seriously high power hikes.

Giulia Handling/Suspension upgrades

Handling modifications are often a priority for the Giulia.

Drop the car optimally somewhere in the region of 26 - 40 and fit modified stiffer dampers, bigger drops will need other modifications in most instances.

Adjusting the handling is often the first step in using the Giulia.Adjusting the Giulia's handling is often the first step in modding it.

When it comes to modding your Giulia, one of the most often cited reasons is to better its handling. However, we regularly witness the same mistakes.

Adjustable Coilovers allow you to adjust your ride height and this allows you to tweak your handling.

What considerations must you make when setting up and selecting your suspension if your Giulia serves as a daily car as well?

Improvements to the bushings

Enhancements to the bushings: Things you need to know

It is possible to connect the Giulia's suspension components to the chassis of the Giulia using poly bushes, which are direct replacements for the original rubber mounts. The rubber ones typically degrade with time and need replacing anyway so why not upgrade.

By replacing new OEM rubber bushings, you may greatly improve your vehicle's performance.

Because the polyurethane bushes are firmer, the ride may be a bit more harsh, but they will last longer and maintain the handling.

Worn bushes may also accelerate the demise of other suspension components due to the increased vibration and play.

A new set of polyeyurothane bushes will assist in lessen the excessive play associated with rubber bushes.

Some polyeyurothane bushings are hard to locate, but most will find the Giulia primary mounts readily available in their local stores Often, custom Giulia polyeyurothane bushings may be manufactured to your requirements.

A frequent misconception is that the best setup would be a non-adjustable suspension system that lowers the vehicle by 90mm purchased from a franchised component shop.

Vendors may claim that their Giulia suspension kits are compatible with any or all model year Giulias.

The 'compromized' approach is obviously a flawed assumption when it comes to adequately supporting a diverse variety of cars. Engine weights and trim levels, and even alloy rims will affect the handling and require different suspension setups.

How low should you go on the Giulia?

When it comes to road vehicles, the maximum suspension drop is 26 - 40 mm, but when it comes to cars that are factory fitted with lowered springs, the maximum suspension drop is 18 mm, according to TorqueCars.

These tolerances may be drastically lowered if the wheel size is changed. Even with 17" wheels and stock suspension, lowering the vehicle might result in lots of issues.

While the fact that the Giulia being lower allows for less air to travel underneath it may aid in stability, the ultimate goal should always be to enhance handling. When lowering the springs, it is critical to use the proper shocks that match all round.

Good suspension tweaks that substantially benefit handling for the Giulia include a couple of degrees negative camber and 1-1.5 degrees of toe (set out to improve cornering or in for better stability) on the front wheels.

For radically enhanced stopping put better high friction brake pads and mate this with bigger discs.

As a word of warning please note that motorsport brake pads can grind and will need to be hot before they bite.

On your regular commute to work the brakes are occasionally used, therefore won't be as effective at slowing you up so source brake pads which have a low working temperature.

Giulia Alloy wheel upgrades.

Alloy wheels will help the brake cooling and are usually lighter than steel ones. Large Giulia alloy wheels can decrease performance. If you get big alloy wheels you will be changing your final drive ratio.

Because of this aim to keep the overall rolling diameter of the wheel your OEM settings. In all cases not going over 18 inches.
