Just called jim berry to fix/revamp the nismo twin plate i just pulled out of my 33gtst, he quoted 1350 for a new and differant centre, new clutch plates and all surfaces machined. Little more than what i was expected, but he says it will last the punishment ive been giving the old one. Just said 450hp at the wheels and doing 3rd/4th gear powerskids plus a few dabs of the far left pedal here and there to get the thing on song. He didnt offer any choices regarding organic or ceramic clutch plates though, so dont know if thats the 'full monty' or not.
