That LPR engine is as powerful as a chainsaw or lawnmower, you're going to need to seriously beef up the drivetrain from front to back. Steel cvd's, alloy rims. As for the clutch, either to a Hot Racing 3 shoe, or Reds 4 shoe, though HR makes that bidirectional one that has a lot of surface area. Transmission case is gonna need to be upgraded to alloy if you haven't done that. Diffs will need to be beefed up, they are a big failure point with that much power as well.
