do you want to turbo?
do you want to use nitrous?
how much do you have to spend?
have you upgraded to good tires and disk brakes(good idea if your going to making good power)?
someone elses opinion probably wont be right for you so SEARCH this site is full of information about EVERYTHING you could want.... also try my friend google.com then once you have your ideas narrowed down and you couldnt find your answers posted in here somewhere ie. archived articles, other threads. then post up specific questions and you wont get smartass answers like this and actually get helpful information.
so have fun searching and good luck. and also put up some pics
