Steve Dinan has been building high performance and racing engines for BMW’s since 1977, and has won 11 racing championships, including 3 prototype championships and two – 24 hours of Daytona. The same engine shop that builds the racing engines also builds the street car engines. This group of talented engineers, engine machinist and engine builders has built hundreds of engines. From rebuilds to developing engines, they make over 625hp on an S65 and over 740hp on an S85.
Steve Dinan’s CARBAHN Autoworks now offers a full line of rebuilt and high performance engines.
The N20 engine is not designed to have a large increase in boost. The engine is known to have connecting rod failures as well as oil starvation under hard cornering. If you are planning a large power increase with bigger turbo’s, CARBAHN Autoworks has designed a high-performance engine to handle very high output. We are utilizing CP forged pistons and Carrillo connecting rods. This Engine includes a complete rebuild with a valve job with new bearings, seals and gaskets. In addition, we have manufactured a high volume oil pan with baffles and a redesigned pick up that ensures oil pressure for up to 2 lateral g’s!
