There are many options on strengthening the GT-R’s gearbox coming to market these days but none so mind blowing as the full gear set we just laid eyes on from Pfitzner Performance Gearboxes (PPG) out of Australia. The full first through sixth gear upgrade is manufactured from high-carbon steel, CNC’d to PPG’s specs which increase gear contact area by up to 40% (first gear). Combine the superior materials used with the heat treating process and the gears are up to twice as strong as standard.

These should suit the high power street GT-R to around the 700 – 900 hp (engine) range.

Head on over to GT-RR.com for the details on pricing and availability.

Thanks to Mike @ GT-RR for the heads up.
