Perodua Alza Tuning

"Thank you for reading our Perodua Alza tuning article."

The Alza is a good tuning project to execute. Think carefully and research Alza tuning to save yourself making the usual disastrous slip ups we frequently hear about.

Handling/Suspension upgrades

Handling modifications are often a priority for the Alza.

Fully adjustable suspension allows you to fine tune the handling of you Alza usually improving your drive.

We would go to a maximum drop of 23mm - 39 mm on most models. You risk handling compromises if you go lower than this.

Top end power should be your overall aim on the Alza with a nice fat peak torque band.

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.

The following sports mods are usually installed by our members, decide how far you want to push your car before you get going.

Getting the right sports modifications 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, Panel air filter, Engine Tunes/Remapping, Suspension upgrade (drop 30-40mm), Alloy wheels.

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

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

You need to keep as much low end torque as possible and aim for a wide power band rather than a narrow top end power hike.

The whole point of our tips is to give a limited introduction of customizing performance parts and point you in the right direction, our forum is best place to go if you need more detailed advice and tips on your car tuning project, the best modified kits and all aspects of modding cars.Fast road cams offer one of the biggest torque gains for your money as far as a bolt on sports modifications goes on a NA (naturally aspirated) engine.

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 cam upgrade with other mods and finish with a tune/remap for the best performance gains.

When pushing up the power you will need to pay attention to the fuelling. More power needs more fuel.

If you find you experience flat spots and surges after your uprated modifications you should check the fuelling and try a higher octane fuel as well. Bigger 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. 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 limitation.

Maximum power gains come from a full induction kit with a cold air feed on heavily tuned engines, this can be sited within an air box but a panel filter should suffice for most applications. TorqueCars suggest you use a panel air filter as these are easy to clean and maintain and generally perform better than paper ones.

Sports exhausts generally help improve air flow out of the engine but do not go too wide or you could very well end up with a reduced flow rate. So generally speaking, keep to 1.5 to 2.5 inches for best results.

Airflow through the head can be dramatically increased with some professional flowed (porting and polishing). These should match and be setup to take into account any other engine mods. A good fast road uprated clutch will help to keep that power going where it should. Never cut corners or ask a standard OEM clutch to cope. The best mods we would do for your Alza are remaps, sports camshafts and induction improvements.

NA (naturally aspirated) engines do not achieve big power gains if you tune/remap them, unless you have done extensive modifications. With turbocharged engines this is another story. A tuned/remapped turbo will give big power gains and take full advantage of the strength of the block. The most significant power gains for NA (naturally aspirated) engines usually involve the addition of forced induction. Turbos are often harder to add than a supercharger. It is harder to map a turbo as the boost builds exponentially with rpm.

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 lowering your unsprung weight and better brake cooling. Don't forget that your choice of rubber greatly affects your cars grip and handling. It is not worth compromising performance with cheap tyres when you can buy directional tread pattern performance tires.The downside to large alloys on your Alza is that you're altering your effective final drive ratio and this will have a detrimental effect on acceleration and performance.

Due to this fact try to keep the overall rolling diameter of the wheel the recommended OEM sizes. In all cases we do not recommend going over 16 inches.
