low to mid 13's. So I dont know what they are talking about.

Wow I always thought they were quicker than that. Hell my 97 Cobra right now is at a mid 12...Kinda depressing to hear since I'm ditching this mustang soon and looking for a a supra, nsx, or 04 cobra...

Low 13s is bone stock. At bpu++++ (no nos), mid to low 12s is achievable (possibly even high 11s in ideal conditions) with drag radials. Add a single turbo or nos and you're firmly in the 11s with ET Streets. Add a larger single turbo and a fuel system (or a bigger shot of nos and your in the 10s with slicks. Keep us posted if you get a Supra...

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?

This is a turbo car...just turn up the boost and make as much power as you want. Be sure to run 93 octane at less than 16psi and add 100+ octane race fuel at more than 16psi. When you hit about 425rwhp, you'll be maxing out those injectors.

so in Japan they are just running at lower boost levels?

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
