Ever notice how most japanese supercars are rated at 276hp or 280hp? I read it a long time ago but it has something to do with the japanese government and auto makers having a "getlemans agreement" to keep hp levels to a maximum of 276hp. Didnt know the Z was like that too but Ive always noticed the Skyline was.

And ummm...This should be quite interesting with the Z "owners" situation
