You got to pay to play, dude. Even then, money will only get you so far. Being affluent and proactive to search out answers to your questions and researching diligently before making decisions is as equally important.

Best piece of advice I can give you for now is to stop trying to make the car fast. It will never be fast because you don't have the resources to make it fast, plain and simple. Do a full tuneup and get the car running well, strip all the crap you put on it off, and enjoy reliability.
