Nick the list I gave you including cam and chip should be around your budget for the next year. That setup can push you well over 325 HP pretty easy without doing anything internal to the engine.

When you say you want a shitload of hp how many are you talking about? Keep in mind that running more than 400-450HP in a daily driver can start to be a pain. If you just want short bursts of massve acceleration you could always use N2O.

If you want to do some reading up, there are quite a few books out there (SA Designs prints allot of them) that can show you various ways of increasing your HP.
