Dont talk to Kaxe, he'll end up trying to convince you to supercharge

. What you do to it depends on what you want out of your car. If your just trying to free the engine up a bit, you want a K&N and maybe a new manifold. Then add a new exhaust, cams and remap. Don't remap until you have finished modding otherwise it's a waste of money. Unless your minted I suppose

If you still want more power have a look at a supercharger and/or throttle bodies but consider that with this much extra power you'll need a new clutch, brakes and ideally a new diff

Or to keep things simple, just do what Steve suggested and go to Mountune!
