Alfa Romeo 75 Tuning

"Thank you for reading our Alfa Romeo 75 tuning article."

The 75 is a good tuning project to try, the 75 replaced the Giulietta running from 1985 and 1992.

With the right mods your 75 can be transformed into a stunning project. Don't waste money, do your homework and follow our unbiased guides to each performance upgrade to avoid disappointment.

The Alfa Romeo 75 have loads of potential and with carefully chosen performance upgrades like remaps, turbo improvements and camshafts you will greatly maximize your driving enjoyment.

We shall examine 75 tuning and summarise the greatest upgrades.

Handling/Suspension upgrades

Handling modifications are a good place to start for the 75.

Adding some negative camber to the front and a few degrees of toe (in for better stability or out to improve cornering), will usually improve your 75 in handling and cornering.

Drop the car by as much as 27mm - 39 mm. and fit performance stiffer dampers, bigger drops will need other modifications in most instances.

For sharper enhanced stopping add better high friction brake pads and match this with better brake discs.

As a word of warning please note that motorsport pads will be noisy and will need a lot of heat before they start to work.

On a road car the brakes are only applied now and then so will not stop you as well so select pads which work well in daily use.

Don't just look at the peak power figures, you need to see the whole torque curve when determining if a mod is right for you 75.

Keep your car looking standard and remove the badges to make an awesome sleeper!

Sadly with smaller engine sizes you are wasting your time spending money on modifications, so if this applies to you get yourself an engine swap then apply the following mods.

Engine Tuning.

These are the performance mods are usually installed by our members, decide how far you wish to go in your tuning project before you begin.

Getting the best performance mods for your planned usage of the car is vital. Stage 3 motor sport parts just don't work well on the road difficult in stop start traffic.

  • 1.6 L I4 (petrol)
  • 1.8 L I4 (petrol)
  • 1.8 L I4 (t/c petrol)
  • 2.0 L I4 (petrol)

500 examples of the Turbo Evoluzione were produced to meet homologation regs for Group A.

Typical stage 1 mods often include: Panel air filter, Lighter flywheel, Alloy wheels, Sports exhaust, Suspension upgrade (drop 27mm - 39 mm.), Remap.

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

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

Peak power is nice in motorsport but for a daily driven car you need a wide power band and perhaps extending the rev range.

In this article we shall give a brief overview to the best modifications for your car, but we'd encourage you to spend some time on the site looking into the details of each type of performance upgrade.One of the biggest mechanical sports parts you can do to your NASP engine is to fit a fast road cam .

The exhaust & intake durations play a big role in your cars power band, but be careful here, getting this wrong can upset the idle and make the car impossible to drive in traffic. You'd need to follow a cam upgrade with other mods and finish with a performance chip for the best performance gains.

Don't forget to pay attention to the fuelling when you are increasing the power - it makes the car more thirsty.

If you find you experience flat spots and surges after your motorsport kits you should check the fuelling and try a higher octane fuel as well. Improved injectors will enable you to supply sufficient fuel to the engine.

A fuel pump will only deliver a finite amount of fuel, so you may need to uprate this if your injectors are demanding more fuel.

Intake and Exhaust Tuning.

Breathing mods are usually next up.  Air induction kits will only help to increase power if your cars air intake is struggling! Adding an induction kit to most small engines will see NO LOW END POWER GAIN AT ALL. If you have heavily modified your engine and it's need for air INCREASES DRAMATICALLY then an induction kit is the answer and will help remove this restriction.

Induction kits can work well on turbo engines and larger engines (if supplied with a suitable cold air feed or air box), generally though we'd just recommend for 75 engines you should go with a high performance panel air filter preferably made from cotton.

Sports exhausts will certainly help air flow through the engine but avoid an exhaust that is too wide or you might just stuff your flow rate and make things worse. So generally speaking, keep to a size of 1.5 to around 2.5 inches to maximise flow rates, and this should take into account the amount of air your engine is moving.

Getting a professionally flowed (ported and polished) head with larger valves can fully release the engines power. When you tune up your 75 you will reach a point that the standard clutch starts to suffer so get an uprated clutch. The best mods in our opinion for your 75 are remaps, sports camshafts and induction improvements.

Remaps offer large power gains on all turbo charged cars. On NASP engines the benefits are doubtful. However a flashed ecu on a NASP engine will help unleash the potential if you have done a lot of mods. Despite the large cost involved adding forced induction to a NASP engine will give large power gains. Turbos are generally harder to add than a supercharger. With a turbo the boost curve is related exponentially to the engine speed making it harder to map.

It is simpler to map a supercharger because the boost is correlating to engine speed on a linear curve. Decreasing the engines compression ratio will allow you to add forced induction, water injection may also help prevent detonation.

Alloy wheel upgrades.

The benefits of alloys include a lower unsprung weight and better brake cooling. If you are serious about performance then you will need to carefully choose your tires - ideally with a soft compound tire. The drawback to large alloy wheels on your 75 is that you're changing your effective final drive ratio and this will have a negative effect on acceleration and performance.

Due to this fact try to keep the overall rolling diameter of the wheel the same as supplied from the factory. In all cases without going larger than 17 inches.
