Sports exhausts can usually air flow out of the engine but avoid an exhaust that is too big or you could will reduce the flow rate. 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 Eclipse engines you should just fit a performance panel air filter preferably made from cotton. The next area for modification is the intake and exhaust. Contrary to popular belief there is often very little if any power gain reached 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! ![]() ![]() To get sufficient fuel you may need to increase the injectors on your engine.Ī fuel pump will only deliver a finite amount of fuel, so you may need to uprate this if your injectors are demanding more fuel. Using higher octane petrol is another option if you find you are suffering from pinking or premature ignition on your Mitsubishi project after fitting other sports upgrades. When pushing up the power you will need to increase to the fuelling. TorqueCars would caution you not to go with a competition cam as this upsets the engines idling and general town driving characteristics. Ideally you'd add other mods and finish up with a reflashed ECU. It improves the intake and exhaust durations and increases the power if done right. The aim of our tips is to give a starting base of car tuning 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 modified upgrades and all aspects of modding cars.Fast road cams offer one of the biggest torque gains for your money as far as a solitary uprated mods goes on a NASP engine. You need to keep as much low end torque as you can and aim for a long power band across the rev range rather than a narrow top end power spike. Stage 3 mods: Competition cam, Adding or upgrading forced induction (turbo/supercharger), Sports gearbox, Internal engine upgrades (pistons/head/valves), Engine balancing. Stage 2 mods: high flow fuel injector, Fast road cam, Ported and polished head, Power/Sport clutch, fuel pump upgrades. Stage 1 mods: Lighter flywheel, Suspension upgrade (drop 30-40mm), Sports exhaust, Alloy wheels, Remap, Panel air filter. Also you can look to perform head mods (flowing and porting), bigger valves, fast road cams and forced induction upgrades to improve fuel. Fuel to Air ratio is vital so upgrade the fuel pump & injectors. Expect 10-20% on NASP engines and 30-40% on turbocharged units.Įvery tuning project will aim to increase the air supply, but fuel supply is just as vital and will need to match the air the engine can utilise. ![]() While some cars can be easily remapped, others may require piggyback ECU's or aftermarket ECU's but this is the most vital step of your tuning project as it fully releases the power from all of your mods and upgrades. Whilst most engines can cope with mild tuning mods, TorqueCars recommend that you upgrade the internal components before these weak spots manifest themselves. Tuned cars will show up weaknesses, typically in the turbochargers, clutch and internal engine components. If the intake or exhaust are restricted in any way this will have an impact on your cars performance, so use an induction kit/filter upgrade and better flowing exhaust whenever your tuning creates a flow restriction.īraking, Suspension and general alignment of the suspension components is vital for any tuning project even before you start increasing power.

Stage 3 competition upgrades just won't work well on the road and will make the car undrivable. ![]() Getting the right tuning upgrade kits for your planned usage of the car is essential. These are the tuning upgrades are usually carried out by our members, decide how far you wish to go in your tuning project before you get going. Engine swaps are a good option if you have a small engine size. Smaller engines do not provide much of a return in terms of power so start with a bigger engine. Eclipse make good sleepers if you debadge them and fit the most powerful engine mods and handling upgrades you can find!
