im from canada importing a skyline from japan, and ive done piles of research, and many sources have stated the skyline puts out about 340 awhp, opposed to the quoted 276hp. it was regarding a gentlemans agreement among the japanese automakers not to advertise above that or something. either way what truth is behind that? and what kind of realistic gains would suction exhaust boost controller and cam gears yield? thanks! keeping in mind im bringing in an r32 gtr 1992.
