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!
