I think most of my setup is good for 700bhp, I have the supra diff and cover in the rear on 6 degree beam, oppliger close ratio box (rated to over 700 bhp) though you prob wouldn't need the close ratios? And quaife front lsd. The weak point on mine being the 3.9 crown wheel and pinion up front, if that breaks then its £3,500 r n d diff.

The tyres will have come on a bit since Rods high speed runs with the Cardigan on.
