you need a hell of a lot more shit that just a T25 and some piping...
i think you need to do a lot more research on turbos or you're gonna get ass raped by any shop you go to...
H22, bolt in affair for an accord, 200 easy HP, and you should be happy with that power increase...
you wanna smoke integras, and you have 500 bucks, then go nitrous...
and a price on a custom built turbo... probably around 2K for a decent setup, especially considering all the parts you still need to acquire...
look into a DIY kit...
i hear the DSM turbo manifold will bolt to an F22 with slight modification... and you already have the T25...
tubing, oil lines, intercooler, FMU, and you'll be ready to throw a rod...
good luck
