ok, a healthy stock series 1 R32 GTR with only the restrictor removed will make about 170rwkw,
i had 2 6 puks and where grabby, unpredictable and very on/off the 4 puk was worse and the 3 puks was worse again, none of which would hold 231rwkw on a good lunch or quick shift.
the full face are the oppersite easy to slip, very predictable and progressive just like the twin plate, even if you don't want a twin there are some good hyper singles out there that will take 250rwkw but not much more and the good thing with these set ups you get the flywheel clutch plate and cover plate as a direct replacement and if want to unpgrade later they can be converted to twins or even triples
3 of those single plate cost just over the grand mark fitted then i fitted the rest myself cause it was getting to expensive to pay someone, then i sat back and thought about how much it was costing and decided to just go the twin and in the long run it has saved me money and i wish i had of just done it in the first place
rear main seal is a good idea so is the spigeot bearing in the end of the crank
