Today we recieved the first upgraded first gear kit from Pfitzner Performance Gearboxes in Australia to arrive in the US. We’ve had great success using PPG’s products in the past, and when we heard of the problems arising with the GTR’s factory Dual clutch gearbox, we knew they would have a solution in the works. After a few emails down under we learned they indeed had a solution in the works, so we began discussions to bring this kit to the United States. PPG beefed up the 1st gear width and the width of the accompanying gear shaft as well using their state of the art machinery. Once a heavier duty gear was machined, they treated the gear to their “control atmosphere” heat treating process, ensuring that the gear would case hardened for added strength. Using a computer controlled atmosphere (furnace) where carbon and other elements are monitored and maintained at optimum levels via highly advanced software and sensors, ensures accurate and efficient heat treating, consistently producing a well hardened and strengthened product for Pfitzner customers.
This first kit will be installed in John Reese of Samurai Speeds record setting R35 GTR in the coming weeks. John’s original first gear broke after many launches using the factory launch control as many other GTR owners have experienced. With this upgraded first gear and first gear main shaft we expect the factory transmission to handle the abuse of hard launches allowing John to continue his record setting pace in Samurai Speeds quest for the first 9 second GTR. PPG is also working on a complete gear set for the GTR which should be available in the near future as well, we anticipate to stock both items for GTR owners looking to take their cars to the next level.
