how many lbs of boost Options

[Kerr1]

how many lbs of boost can a stock 5s head handle....im not worried abt. the internals just the actual head.

so low compression pistons wouldnt b a bad way to start? Im trying to find a ct26 now...is there a diff. between the mr2 one and the supra one? cuz i think i might b able to buy the supra one for like 50 bucks practically new.?

if your going to drop the compression on the 5sfe, you might as well just go with a 3sgte swap. youll get a low compression motor, with a turbo, injectors, and ecu that can handle 15psi on a ct26, just fine. it would probably cost you the same as your motor build up, and the sky is the limit if you want to make more power down the road.
