This special project's goalbwas to back date this 1978 PORSCHE 911 Turbo (930) chassis to the famous 1973 Porsche 911 RSR.
This lightweight chassis is fitted with a custom built drivetrain featuring a 993 twin turbocharged 3.8L engine and 6 Speed transaxle. The engine is precisely controlled by a MoTeC M600 engine management system. The transmission is of our special 993 Short Bell Housing, 6 Speed transaxles. Another little addition will be on-board motorsport inspired, KRONTEC air jack system! And of course a fully adjustable brake and suspension system. Take a closer look!

Here we are as a roller, ready for the engine & transmission fitment!
We have started with a 1996 993 Twin Turbo engine, and performing a complete build to 3.8L using Mahle Motorsport pistons & cylinders (machine in fit), we have fitted the GT2 oil pump, and we will be using GT2 EVO cams & RSR solid rocker arm system. The engine will be controlled with a Motec M600 ecu. We are going to run stainless steel high flow headers & K-24 turbos with a special short extractor!
