Gruppe-S Engineering is proud to unveil the first billet GTR R35 piston!

No cost was spared in the research and development of the most comprehensive internals solution for the true GTR builders out there. There are obviously great forged pistons available in the world, but we worked with the engineers at JE to introduce a piston that can handle the rigorous demands of extreme high horsepower applications.

Currently there are a few engines that are capable of 1200 horsepower, however the engineers at JE Pistons feel that these are the limitations of these pistons. Some engine builders have contacted us and have seen some piston distortion at those horsepower levels and have been looking for an alternative that can handle up to 1600 hp. Well the industry should be happy to know we finally have a solution for those looking to build the fastest GTRs in the world.

Well here it is, and hope everyone enjoys the greatness of this billet FSR piston just built for us.



These pistons are designed from a billet piece of aerospace aluminum and then machined to maximum lightness, narrow pin bosses and the ability to handle the power demands of a 1600 horsepower engine. We are able to maintain the same piston weight as a forged piston but handle the abuse of endurance or drag.





These pistons will be available in many different configurations from stock bore to 100mm with compressions ranging from 9.0 to 10.5:1, the pistons will also be available for your 4.3 liter stroker kit for those looking to set some records. When your GTR requires nothing but the best, choose the Gruppe-S/JE Billet FSR piston.
