Handling/Suspension upgrades

Handling modifications are high on most peoples lists for the Bezza.

We found that most Bezza factory suspension setups need tweaking, a few degrees of toe out for cornering or toe in for stability, -, and some negative camber will often enhance your cornering and handling.

We would go to a maximum drop of 26mm - 40 mm on most models. You risk compromising your handling if you go lower than this.

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 Bezza.

With the right choice of mods you can turn your Bezza into a hot hatch, potentially beating bigger engined cars on the track.

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.

This list of the stages and motorsport mods are usually installed by our members, decide how far you want to push your car before you get going.

Getting the right uprated mods for your planned usage of the car is a time and money saver. Stage 3 motor sport mods just don't work well on the road difficult in stop start traffic.

Best Engine Mods for your car

  1. Mapping - remapping provides the most advantage in terms of cost savings,  aftermarket ECUs, and piggyback ECUs are all alternatives.
  2. Fast road cams are one of the most significant mechanical changes, but they must be installed by someone who knows what they're doing and they are not always easy to source but you might find a local firm to regrind a stock camshaft.
  3. Intake and Exhaust - Note that on their own these mods will NOT ADD POWER in most cases, but they can help enhance power after other mods by removing the restriction.
  4. Upgrades to turbochargers and superchargers - forced induction is the most efficient approach to increase air supply, allowing you to burn more fuel and make more power. It is one of the most costly upgrades but provides the best gains.
  5. Head work - The goals of porting and flowing the head are to get air flowing into the engine while removing flow restrictions and turbulence.

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

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

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

You need to keep as much low end torque as you can and aim for a wide power band across the rev range rather than a narrow top end power hike.

The point of our advice 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 performance modifications and all aspects of modding cars.One of the most cost effective mechanical tuning parts you can do to your NASP engine is to fit a fast road cam .

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 performance chip 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.

Most power losses, and erratic idling after motorsport kits are done can usually be traced to fuelling or timing issues.To get sufficient fuel you may need to uprate the injectors on your 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.

The next area for modification is the intake and exhaust. Contrary to popular belief there is generally very little power gain achieved by fitting an induction kit, they only help and are recommended after you raise the engines power to the point where the standard air intake box cannot cope!

Derestricting the air feed into the engine is the primary part of performance tuning so get a freer flowing air filter if you find that the car is running lean only if you find the car is running lean. Induction kits can sound sporty but due to the warm air in the engine bay they will not do much to increase power and more often than not rob you of power.

Sports exhausts can help increase the flow of gases through the engine. But if your exhaust pipe is too large, ie: it's over 2.5 inches bore, you will lose a lot of the flow rate and end up losing power and torque.

Airflow through the head can be dramatically increased with some professional gas flowing. These should match and be setup to take into account any other engine mods. When you tune up your Bezza you will often find that the standard clutch starts to complain so get an uprated clutch. The best mods we recommend for your Bezza are fast road camshaft, remap, induction and exhaust, suspension.

Remaps offer large power gains on all turbo charged cars. On NASP engines the benefits are doubtful. However a remapped ECU on a NASP engine will help unleash the potential if you have done a lot of mods.

We've also seen some tuners experimenting with twincharged applications and making some very high power figures.

The most phenomenal power gains for NASP engines usually involve the addition of forced induction. Turbos are usually harder to add than a supercharger. With a turbo the boost curve is related exponentially to the engine speed making it difficult to map fuelling with.

The nice steady boost and rpm characteristics of the supercharger make them easier to map. Adding forced induction will usually require a lower compression ratioor water injection.

Alloy wheel upgrades.

Alloy wheels will help the brake cooling and are generally lighter than steel ones. Further improvements can be made to your cars handling with the addition of soft compound tire. We'd like to point out although they can look cool on the Bezza big alloy wheels will actually decrease your performance. The larger you go the lower your acceleration will be - this to the change in your effective final drive ratio.

With this in mind aim to keep the overall rolling diameter of the wheel the OEM setup. In all cases not going bigger than 16 inches.
