It doesn`t. There is a black Supra in my town that makes 1172HP AT THE WHEELS! I`ve seen the dyno sheet, some of my friends work for the dude. Yes, I`d much rather drive a Z, but supras make ungodly power with little effort, as will any straight 6. Top Secret in japan has an RB powered supra(skyline motor if you aren`t familiar) that makes roughly 950bhp. It all doesn`t really matter anyway.Cram enough boost into any engine and it will make power. 30 psi into a 2.0 litr will make 500 HP.And who cares? do any of us have the means to build a 1000 HP vg30? I could do it if I had a spare 30 grand but I don`t so I`ll shoot for the 700 mark as my "stopping point". The extra 300 horses isn`t worth the extra 20 grand.I`d rather buy two more Z`s and have 600 more :-)
