theres a faq on how to get cheap but quick hp,,
alot of people will tell you to do an engine rebuild with a thicker/metal head gasket.. increase your turbo psi and/or bigger turbo with like 8 psi.. full exhaust w/out the resonator, and then straight piping from a cat back to a aftermarket exhaust...HKS dual tip is actually the only i know of right now that increases the supra hp, and is proven on the dyno.. but this one is a quiet rumble... and also im sure there is other exhaust tips that increase hp but idk...
as for exhaust headers. i heard that theres no point, but idkk...
bigger intercooler, lexus afm, and 550cc injecters to compensate for the bigger afm.. hgiher boost! haha, but gotta do alot of work so you dont blow your engine..
theres more, just look at the faqs
