The laws of momentum are against us on this one. That`s why you see shitloads of 800 HP supras and most frequently see a Z in the 550-600 range for the same work and money. We have a V motor, and the rotating assembly fights against itself. Retro fit an RB motor into the Z and make some serious power Japan style! It`s been done, by the way. Think skyline power with Z looks.damn.
