I would also take a TT Supra over any Skyline GTST/GTT.
Gear-box and motor are heaps stronger than any RB20/RB25 and they make good power with minimal mods.
A friend has one with a FMIC, turbo back exahust, fuel pump and pods, running 14.5psi boost on stock turbo and it makes 248rwkw. Can't complain about that?
But if its an NA Supra its fairly useless.. there fair flow but suprisingly not tooo slow and NA sounds gay, unless its 5.0L +
