Guess what broke on Project RH9? Another factory transmission. Old school Turbo readers might be seeing visions of another Project Talon in the works. To be honest, I’m picturing the same thing.

Back in the days, Project Talon chewed up every single available transmission in the Southern California area. All totaled, close to $10,000 was invested in factory transmissions that couldn’t last a full pass. Learning from our lessons of yesteryear, we decided to research our transmission options for our GT-R.

The Close-Ratio Aftermarket Gear Sets

A number of companies produce aftermarket gear sets for the factory gearbox. These gear sets feature improved ratios as well as a higher- strength material. From our research, we’ve heard of many applications making about 600 wheel horsepower that effectively used these gear sets.

The Straight-Cut Gear Sets

There are also a couple of manufacturers that offer straight-cut gear sets for the factory gearbox. These offer additional strength but are considerably noisier than the bevel cut gear sets.
