This engine is the lower end only. This engine is for owners who have low mileage cars that have not had an engine failure and do not need a complete overhaul but just want a stronger engine for higher power applications. It is designed to make the S55 engine strong enough to handle high boost applications.

If you are planning a large power increase with bigger turbo’s CarBahn has designed a high-performance engine to handle very high outputs by pinning the cam sprocket to the crankshaft. To ensure durability we also machine the block to accommodate a full circle thrust main.

The stock high compression ratio is high for CAFÉ. (Corporate average fuel economy). However, this increased compression limits engine performance with higher boost setting by decreasing the size of the fuel air charge in the combustion chamber and by forcing the ignition timing to retard far below MBT (mean best timing). The CarBahn engine has .5 less compression to optimize the engine for the increased boost.
