Kia Stonics great bases for a tuning project and with the right motorsport parts you can dramatically increase your driving opportunities.

The Stonic is a awesome car tuning project to do. If you do your homework then you can create an awesome Stonic but don't be fooled there are lots of tuning upgrades out there that will simply not suit it read our unbiased guides first.

Handling/Suspension upgrades

Many Stonic owners uprate the handling of their cars with performance suspension mods as a priority, this will certainly increase your enjoyment of the car.

Fully adjustable suspension allows you to fine tune the handling of you Stonic greatly enhancing your drive.

We suggest that you fit modified suspension and lower the car by 25mm - 36 mm. Larger drops require arch work - especially on models already equipped with performance suspension.

Turning our attention to the Stonic's engine we need to get a bit more power out of the top end.

Stonic make good sleepers if you debadge them and fit the most powerful engine upgrades and handling mods you can find!

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.

Power mods.

The following motorsport kits are usually fitted by our members, decide how far you wish to go in your tuning project before you get started.

Getting the right modified upgrades for your planned usage of the car is a time and money saver. Stage 3 competition upgrades just don't work well on the road and will make the car undrivable.

Stage 1 mods: Panel air filter, Suspension upgrade (drop 25mm - 36 mm.), Remap, Lighter flywheel, Sports exhaust, Alloy wheels.

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

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

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

In this article we shall give a limited introduction to the best modifications 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.One of the most cost effective mechanical tuning mods you can do to your NASP engine is to fit a fast road cam .

The intake and exhaust valve durations play a huge factor in your cars power band, but be careful here, getting this wrong can upset the idle and make the car challenging to drive in traffic. You'd need to follow a cam upgrade with other mods and finish with a reflashed ECU to fully realise your gains.

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

Using high octane petrol is another option if you find you are suffering from pinking or premature ignition on your Kia project after fitting other tuning kits. Upgrading the injectors is another beneficial modification and will deliver sufficient fuel.

Uprate the fuel pump to cope with the extra fuel requirements of your tuned Stonic's uprated injectors.

Intake and Exhaust Tuning.

Now we move on to the intake and exhaust and ensure proper flow through the engine.

Air induction kits only help to boost power if your cars air intake is restricted! Adding an induction kit to most stock engines will see NO LOW END 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.

Induction kits can work well on turbo engines and larger engines (if supplied with a suitable cold air feed or air box), generally though we'd just recommend for Stonic engines you should go with a high performance panel air filter preferably made from cotton.

Sports exhausts balance the flow of air through the engine. But if your exhaust pipe is too large, ie: over 2.5 inches bore, you will lose much of the flow rate and end up losing power and torque.

Airflow through the head can be dramatically increased with some professional head porting and polishing. These should match and be setup to take into account any other engine mods. A good heavy duty fast road upgraded clutch will help to keep that power going where it should. Never skimp or expect a standard OEM clutch to cope. The best mods in our experience for your Stonic are a remap especially on a turbo, a fast road camshaft and sports exhaust, with a good air intake.

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

We've also come across some owners playing with twin charging applications and making some very high power gains.

Adding forced induction will see significant power gains but this is usually too expensive to be cost effective. It is often simpler to add a supercharger than it is to install a turbo. It is more challenging to map a turbo as the boost comes on exponentially with rpm.

The nice correlating boost and rpm characteristics of the supercharger make them simpler to map. To cope with forced induction you will usually need to decrease the engine compression ratio .

Alloy wheel upgrades.

Because alloy wheels are less heavy they improve performance and they help to cool the brake disks. Pay attention to your choice of tyres (tires) for your car, a good directional tread pattern tire can really enhance your cars handling. It is worth noting that although they can look cool on the Stonic 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 we would advise sticking to a maximum wheel size of 18 inches, although we know some of our members have with bigger wheels with no problems.
