Excedy HD button clutch? Not sure about the flywheel bit, but why not? Just heard its a bitch to drive with or something along those lines. If you can afford it and want to do it properly, go a Garrett GTX3076R with V-band rear housing, Tial external wastegate, 6 Boost high-mount exhaust manifold, get custom intake pipe, intercooler pipes and turbo dump pipe fabricated.
Or search for "Hypergear" turbo's if you want to save a couple grand or so.
