What size flywheel have you got now then? Im guessing 200mm which is a Series 1 Flywheel. They all changed to 220mm flywheels on later cars and is the same for the FRST, and this is what you want really, bigger clutch, less slippage

You can fit a trigger wheel to the alternator pulley end of the crank if you wish.

You'll need an EFI inlet aswell obviously, but seriously, it would be so worth it
