i got a new greddy 3-row for my JDM 95 supra and am interested to increase the boost pressure on the stock twins shortly. i've heard that the JDM ones can only go up to 15psi but i'd like to know what i should run/need BPU to get at least 400HP.

please help..

Well the supra stock ECU wont allow more then 15 PSI unless you get a BCC and or a ecu upgrade, and your saying you want to get maximum boost huh?

what have you done to your car, other then put a fmic in it?

I'm smoking, literally.

well i got the BCC but i havent bought the controller yet coz i dunno if it'll do me any good if i cant boost it normally anyway.

the usual stuff like exhaust, downpipe, air filter, BOV..

thing is mine is the Jap supra so i'm not sure if BPU goes the same way since its 43occ injectors only, among other things.. please enlighten.

Yeah cause japs run the 430, and american ones run the 550cc. your right it would be different.

You should still be able to get 400 (bhp) at 17 psi on the Jap Spec car. It has slightly smaller turbo's as well to go with the smaller injectors.
