Sorry to revive an old thread guys but searching gave me this as a best choice.
Im living in canada and have purchased a supra in Japan, just waiting until may 08 to import it. Im not worried about the car itself but just a general question. as its well known the JDM supra because of japanese laws and the hp limits car manufactureres agreed to they are limited to 280hp from the factory and the North American ones are 320, is there anyway to increase the HP to North American standards without doing BPU or upgrading expensive parts? Basically what I'm asking, is the restriction to 280HP to do with sofware of the ECU or is it hardware related which means I would have to replace the turbo's with steel ones as well as increase injector size along with other mods? |

well I guess I was vague and I apologize. I understand the easiest way to make up the HP difference would be to increase boost that is obvious. But I was just generally inquiring about what caused the difference in hp, if it was just lower boost being used or the internals were causing the difference.
(I know some people may say well duh, different internals will give different results, but thats not always the case, I was just curious) Thank you for the help pwpanas ![]() |

![]() The only thing you missed is the intake side cam (larger duration in the us-spec). Other than that, the internals are identical.
