RENN HAUS is on the downhill side of a very exciting project on this really nice 105,000 mile BMW 635CSi. We are turbocharging the engine but first will rebuild the engine to .030 over with new CP pistons, rockers, springs, port & polished head and turbo grind cam. The compression will be 8.5:1.

Stock horsepower is 218bhp at the flywheel and we are looking to more than double that to over 450bhp. We will Dyno the car at completion and publish the results.

To stop this car we have installed a Big Brake Kit and installed all new poly bushings front and rear. A Sachs Stage 4 clutch combined with a UCC short shift kit will give very precise shifts and feel.

Engine rebuild will start in the next week and we are shooting for completion by early August.

Below are pictures of the turbo, wastegate, intercooler pump, oil catch can, air filter, piping and pistons.
