Kia Soul Tuning

Tuning the Kia Soul and best Soul performance parts.

We examine at Soul tuning and report on the choicest modifications. Kia Souls make awesome project cars and with the optimum modified upgrades you can assuredly increase your driving enjoyment.

The only thing holding you back in your Soul project is time, money and your imagination Sit down first and research Soul tuning to save yourself making the usual common errors we get told about.


Tuning tips and articles

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

Handling modifications are often a priority for the Soul. We suggest that you fit uprated suspension and lower the car by 30-35mm. Larger drops require arch work - especially on models already equipped with motorsport suspension.

Our aim in Soul engine tuning should be to increase peak power and Torque at the top end.

Keep it looking standard and take off the badges for the ultimate sleeper!

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 Tuning.

These are the motorsport upgrades are usually installed by our members, decide how far you wish to go in your tuning project before you get going.

Getting the best performance mods for your planned usage of the car is a time and money saver. Stage 3 (competition) mods just don't work well on the road and will make the car undriveable.

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

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

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

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

In this article we shall give a brief overview to the best mods 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.A fast road camshaft will be one of the best NASP power mods you can do from a single upgrade to your engine.

The intake and exhaust flow play a large part in your cars power band, but be careful here, getting this wrong can upset the idle and make the car hard to drive in traffic. You'd need to follow a camshaft upgrade with other mods and finish with a remap to fully realise your gains.You will need to ensure that the engine is not starved of fuel so will need to uprate the fueling.

Using higher octane petrol is another option if you find you are suffering from detonation or premature ignition on your Kia project after fitting other uprated modifications. 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.

Now we move on to the intake and exhaust and ensure proper flow through the engine. Contrary to popular belief there is often very little if any power gain to be had by fitting an induction kit, they only become beneficial and are recommended after you increase the engines power to the point where the standard air intake box cannot cope! Derestricting the airflow into the engine is a primary goal of car tuners so get a better flowing air filter if you find that the car is running lean. Induction kits can sound great but due to the warm air in the engine bay they will not add noticeable power and actually rob you of power on most cars.

Sports exhausts equal out the flow of air through the engine. But if the exhaust is too large, ie: over 2.5 inches bore, you will lose a lot of the exhaust flow rate and end up lacking power and torque.

Getting the head polished and ported will allow you to get more air into each cylinder. This is definitely a job for a pro with a flow bench. Your clutch can seriously let you down if it starts to fail and the standard clutches are only ever good for power gains of up to 40%. Fit an upgraded clutch to avoid power leak through the transmission.

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.

We've also seen some tuners playing with twincharged conversions and making some impressively high power hikes.

Adding forced induction will see massive power gains but this is usually too expensive to be cost effective. It is generally simpler to bolt on a supercharger than it is to install a turbo. It is harder to map a turbo as the boost comes on exponentially with revs.

 

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

Alloy wheel upgrades.

Because alloy wheels are lighter they improve performance and they will help to cool the brake disks. Large Soul alloy wheels can decrease performance. If you get big alloy wheels you will be changing your final drive ratio.

Although some people have gone larger than this without problems we would restrict ourselves to a 17 inch rim size as the maximum.
