The latest issue of NZ Performance Car features a 260kw M35. I'll try to scan the article tomorrow if I get time but the guts is this:
Started with a 2wd VQ30DE. Computer is Link G4 (wire in ViPec). Gearbox is Toyota R154 5 speed with custom bellhousing, 4 puck clutch, custom driveshaft 350Z diff, Bilstein shocks, Tein springs, 300ZX brakes front and rear, Work 18x9 front and 18x10 rears (widened rear guards), only started on the engine - Masterpower turbo @16psi.
As my local RB guru likes to say "anything's possible if you have the inclination and the money".
