RENN HAUS has the engine rebuild of the BMW 635CSi and it is now ready to be reinstalled. We rebuilt the engine to .030 over with new CP pistons, rockers, springs, port & polished the head and installed a new turbo grind cam. The compression will be 8.5:1 and we think we can get close to 450 horsepower at the flywheel which would be double the stock 218bhp.
So now we will install the engine and then the turbo, wastegate, intercooler and pump. Then sort it out for a few days, dyno tune and then take it to the track to see how fast.
So keep posted.
