Includes:  Forged Rods, Forged Pistons, high performance valve springs for more boost, Ported heads, High flow direct injection cam drive, Labor and machine work for complete overhaul.

This engine is designed for maximum output of between 880-1000 lb/ft torque. The direct injection pump drive is modified to inject more fuel. We also port the cylinder head to ensure maximum flow at high RPM with larger turbochargers.

The S63 engine is not designed to have large increase in boost. CarBahn has designed a high-performance engine to handle very high outputs by utilizing higher quality racing components. This engine includes higher quality racing Forged Carrillo connecting rods, CP forged pistons and CarBahn high-performance valve springs, ported head High performance direct injection cam drive. This Engine includes a complete rebuild with a valve job, timing chains, chain guides, tensioners, water pump thermostat, new bearings, seals and gaskets.

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. If this an emissions legal street car the lowered compression has the added benefit of reducing catalyst inlet temperatures and improved drivability on pump gas.
