Part Number: CB363-6002 Category:


*Note – Core charge may apply. Contact us for details.

This Engine Incudes: Forged Carrillo Rods, Forged CP Pistons, high performance valve springs, modified direct injection pump drive to move the direct injection pump to inject more fuel, resized crankshaft with special racing bearings, ported heads. This is a complete engine with new chains, chain guides and tensioners, labor and machine work to assemble complete engine.

Additional Information

This engine is designed for maximum output engines over 1,000 lb/ft totque. To ensure durability the engine includes a resized crankshaft and rods to accommodate special racing rod bearing for ultra-high output applications. 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 stock engine compression ratio is relatively high due to the Corporate Average Fuel Economy (CAFE) standards which push for consistently higher fuel economy in cars and trucks. However, this increased compression limits engine performance with higher boost settings by decreasing the size of the fuel-air charge in the combustion chamber, forcing the ignition timing to retard far below MBT (mean best timing, the theoretical optimal ignition timing). Therefore, the CarBahn Autoworks S63 engine has 0.5 less compression to optimize the engine for the increased boost. In an emissions-legal street car, the lowered compression has the added benefit of reducing catalyst inlet temperatures and improved drive-ability on pump gas.

CarBahn History

Steve Dinan has been building high performance and racing engines for BMW s since 1977, winning 12 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; these talented engineers, machinists, and builders have built hundreds of engines from OEM street rebuilds to full-blown racing engines.
