G101A 4-Speed Transmission

The G101A is the latest generation of G-Force's 4 speed drag racing transmission. The G101A can be built as either a clutch-less or clutch assisted unit.

The G101A has a centre bearing support that helps keeps the shafts from spreading under high loads. This greatly increases horsepower capability and also prolongs the life of the sliders and faceplates. The G101A will take approximately 1000 HP, depending on the application.

Also, when built as a clutchless transmission, the G101A DOES NOT USE springs between the sliders, which had a tendency to come off in the previous design G101 due to the larger ratio drops in a 4 speed transmission as compared to a 5 speed. The G101A is a great alternative to a 5 speed when looking at cost savings in either a drag race transmission or road racing transmission. The G101A has also been proven to be a very effective drift transmission where center-shift transmissions are not necessary. Also, this transmission has been approved for various spec-type classes worldwide.

These boxes can be made to suit any standard application however here at Powermax Engineering Ltd we have spent a number of years testing various configurations for the ever demanding drift scene across the world. In conjunction with a few manufacturers and suppliers we have put together a complete "bolt-in" kit option for the most popular engine setups including:

• Nissan SR20,
• Nissan RB25,
• Nissan RB26,
• Toyota 1JZ,
• Toyota 2JZ
• Ford YB Cosworth

Powermax is constantly looking at creating additional setups to match engine configurations. Please get in contact if you have any special requests.
