Perodua Axia Tuning

"Tuning guide to the best Perodua Axia modifications."

The Axia is a good project car to have. The key to Axia tuning is finding the right mods - a lot of money can be wasted if you do it wrong.

Handling/Suspension upgrades

Many Axia owners uprate the handling of their cars with sports suspension modifications as a priority, this will certainly increase your enjoyment of the car.

Fully adjustable suspension allows you to fine tune the handling of you Axia substantially enhancing your drive.

Drop the car optimally somewhere in the region of 24mm - 39 mm and fit modified stiffer dampers, bigger drops will need other modifications in most instances.

Our aim in engine tuning should be to increase peak bhp at the top end.

The best power gains come from larger engine sizes. The more you start with the bigger the return on investment so engine swaps are good value mods for small engined cars.

Tuning modifications.

These mods motorsport upgrades are usually fitted by our members, decide how far you want to go before you get going.

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

Best Engine Mods for your car

1. Engine Tunes - engine tuning/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, Lighter flywheel, Engine Tunes/Remapping, Panel air filter, Suspension upgrade (drop 30-40mm), Alloy wheels.

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

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

Peak power is good on competition cars but for a drivable and fun car you need a long torque band and perhaps extending the rev range.

The aim of our advice is to give a starting base of modifying mods and point you in the right direction, our forum is the place to go for detailed advice and tips on your modified car project, the best uprated upgrades and all aspects of modding cars.Fast road cams offer one of the biggest power gains for your money as far as a bolt on uprated modifications goes on a NA (naturally aspirated) engine.

The intake & 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 cam upgrade with other mods and finish with a performance chip for the best performance gains.

You will need to ensure that the engine is not starved of fuel so will need to pay attention to the fuelling.

If you find you have flat spots and power surges after your sports kits you should check the fuelling and try a higher octane fuel as well. Increasing the injectors is another beneficial modification and will deliver sufficient fuel.

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. Contrary to popular belief there is usually very little power gain got by fitting an induction kit, they only help and are recommended after you boost the engines power to the point where the standard air intake box cannot cope!

For most Axia 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 air through the engine. But if your exhaust is too big, ie: it's over 2.5 inches bore, you will lose a great deal of the exhaust flow rate and end up losing power and torque.

Polishing and porting the head will allow you to maximise your air/fuel charge. Leave this to a professional though with a proper flow bench and machine tools A good heavy duty fast road sports clutch will help to keep that power going where it should. Never skimp or think that your standard OEM clutch to cope. The best mods we recommend for your Axia are remaps, sports camshafts and induction improvements.

Turbo engines are just crying out to be remapped. You will see impressive power gains on most modern turbo charged cars including diesels making a tune/remap one of the most cost effective and impressive modifications for your money.

We've also come across some owners experimenting with twincharged conversions and making some seriously high power gains.

Adding forced induction will see large power gains but this is usually too expensive to be cost effective. Turbos are usually harder to add than a supercharger. With a turbo the boost curve is related exponentially to the engine speed making it more challenging to map.

It is more straightforward to map a supercharger because the boost is correlating to engine speed on a linear curve. Adding forced induction will nearly always require a lower compression ratio or water injection.

Alloy wheel upgrades.

The benefits of alloys include a lower unsprung weight and better brake cooling. Pay attention to your choice of tyres (tires) for your car, a good track legal slick tire can really enhance your cars handling. The downside to large alloy wheels on your Axia is that you're altering your final drive ratio and this will have a negative effect on performance and acceleration.

Due to this endeavour to keep the overall rolling diameter of the wheel the same as supplied from the factory. In all cases avoid going larger than 16 inches.
