i just want to bring this up briefly....you're 17, in hs, with a sc'd gsr AND a 97 itr you want to turbo with a $10k budget....wow. did you rob a bank and sell crack? :uhhok:

here's what you'll need for 500hp:
sleeved
forged internals
a big ass turbo
tuning otherwise your engine will turn into a big paperweight
