Tuning a car is nothing to fool around with, you may end up harming the motor. This website has TONS of info, look in the N/A forum section for building techniques and stuff, it'll get you started.
Before you spend ANY money, do your research.
Don't let harsh words piss you off, you won't be here for long if so. But a little grammar might help us understand your needs better.
Take it easy and good luck.
