The CarBahn BMW S63 engine is specifically designed for high-performance outputs, addressing the limitations of stock boost levels. Utilizing superior racing components like forged Carrillo connecting rods, CP forged pistons, high-performance valve springs, ported heads, and a reground crankshaft with stronger bearings, this rebuild is perfect for BMW performance enthusiasts. It also includes a complete valve job, timing chains, tensioners, water pump, thermostat, and new seals, bearings, and gaskets.
The stock high compression ratio, designed for CAFÉ (Corporate Average Fuel Economy), reduces engine performance at higher boost levels. CarBahn's engine lowers the compression by 0.5 to optimize boost and improve drivability on pump gas, while also reducing catalyst inlet temperatures for emissions-legal street cars.
Key features include forged rods, forged pistons, high-performance valve springs, ported heads, and a reground crankshaft with stronger bearings, along with labor and machine work for a full overhaul. As a top BMW tuning company, CarBahn ensures a reliable, high-output engine.
Engine core acceptance parameters:
