What I hear is you can make more power with a Supra with less modifications. I also have heard that if you have a TT and a Supra with same horses and torque that the TT still will be quicker. They say you are better off having a 600hp TT than a 680TT supra. Then I again I don't know and these are rumors. Is that really true that the Supra is not quick as the TT.
