PPG Transmission Upgrades for Nissan R35 GT-R
Australian gearbox gurus Pfitzner Performance Gearboxes (PPG) have completed their first Nissan GT-R GR6 gearbox upgrades in the form of a drop in first gear replacement. You can see it pictured about sitting next to a standard GR6 first gear.
You can tell just by looking at this picture the basics of this upgrade, a much wider gear to increase strength. The main cause of gearbox failures occurs on the teeth of the first gears after extreme stress. Initially fractures develop and eventually teeth give way. Once one tooth is gone the rest follow like dominoes.
To follow on from this, PPG plan some gear upgrades for big horsepower cars as well as a 1st through 4th gear upgrade set.

Best Performance modification so far for the GT-R!! Hope it proves that it can withstand the brute-force of the engine..
PPG make solid gear upgrades for the R32/R33 GT-R. I have drive a couple of cars with their gearsets. Both 900-1000 hp cars. One with straight cut gears and one with helical cut.
The limiting factors are being worked on . Now just need a good twin clutch, and some TCM reprogramming.
Just wondering how the wider gear will fit in the stock housing?
