Toyota Auris Tuning

Tuning the Toyota Auris and best Auris performance parts.

We examine Auris tuning and report on the choicest modifications. Toyota Aurises (or should that be Aurisi?) have loads of potential and with the best performance modifications you can really maximize your driving pleasure.

We have seen some awesome Auris tuning projects and there seems to be quite a loyal fan base of Auris owners. Think carefully and research Auris tuning to spare yourself making the usual common errors we regularly come across.

Tuning tips and articles

Engine tuning Transmission tuning Care care Intake & exhaust mods Improve handling Forums

Improving the handling for people first priority in your Auris tuning project. We suggest that you fit sports suspension and lower the car by 30-35mm. Larger drops require arch work - especially on models already equipped with motorsport suspension.

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

Enjoy your Auris to the limit with our solid tuning pointers - do the right mods in the right order.

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.

Engine Options were
Petrol 1.33L 101 hp, 1.4L 97 hp, 1.6L 132 hp, 1.8L 147 hp, 2.4L 158 hp (Very nice option), 
Diesel 1.4L 90 hp, 2.0L 126 hp, 2.2L 177 hp, 
Later in 2012 we saw a Hybrid model based on the 1.8L VVT-i 1,798 cc when the larger diesel engines were dropped from the range
Transmission 4-speed automatic 5-speed multimode 5-speed manual 6-speed manual 7-speed CVT (in Japan) 

Engine Tuning.

These mods modifications are usually carried out by our members, decide how far you want to go before you get started.

Getting the right sports upgrades for your planned usage of the car is vital. Stage 3 motor sport parts just don't work well on the road and will make the car undriveable.

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

Stage 2 mods: Power clutch,Fast road cam,Ported and polished head,Fuel injector & fuel pump upgrades,.

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

You really need to keep as much low end torque as you can and aim to get a long power band across the rev range rather than a narrow top end power spike.auris-tuning

The whole point of our articles is to give a little insight into the world of modding mods and point you in the right direction, our forum is the place to go for detailed advice and tips on your car tuning project, the best uprated modifications and all aspects of modding cars.A fast road cam usually works out as one of the best NASP power modifications you can do mechanically to your engine.

It maximises the intake and exhaust durations and increases the power if done right. Ideally you'd add other mods and finish up with a performance chip. We'd also caution you not to go with a motor sports profile cam as this upsets the engines idling and general town driving characteristics.Don't forget to pay attention to the fueling when you are increasing the power - it makes the car more thirsty.

If you find you get flat spots and power surges after your sports modifications you should check the fueling and try a higher octane fuel as well. Uprated 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.

The next area for modification is the intake and exhaust. Induction kits are only beneficial to boost performance if the cars air intake is struggling! Adding an induction kit to most standard engines will see NO 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. 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.

Do not go with the widest exhaust you can buy this will reduce the exhaust flow rate - the best for power gains are usually between 1.5 to 2.5 inches. It is the shape and material more than the bore size.

Head porting and polishing 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 multi plate fast road power clutch will help to keep that power going where it should. Never cut corners or think that your standard OEM clutch to cope. NASP engines do not achieve big power gains if you remap them, unless you have done extensive modifications. With turbocharged engines this is another story. A remapped turbo will give impressive power gains and fully release the potential power of the engine. Adding forced induction will see large power gains but this is usually too expensive to be cost effective. Superchargers are generally easier to add than turbos. Turbos provide boost in increasing proportion to rising engine speed and this can make mapping difficult.

The nice steady boost and rpm characteristics of the supercharger make them easier to map. Decreasing the engines compression ratio will allow you to add forced induction, water injection may also help prevent detonation.

Alloy wheel upgrades.

Because alloys are less heavy they improve performance and they help to cool the brake disks. Please note that although they can look cool on the Auris large 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.

Although some people have fitted larger wheels we would restrict ourselves to a 16 inch rim size as the maximum.
