The CarBahn ST2 S63 engine is rated for 1,000+ lb-ft of torque. It’s designed to improve durability for high-output tunes, making it an excellent alternative to an OEM factory remanufactured engine. We use high-quality racing components, including Carrillo connecting rods, forged CP pistons, high-performance valve springs, a high-performance head gasket, and cylinder head studs. The compression is lowered by 0.5 to maximize power for higher boost settings without risking detonation issues.

The CarBahn S63 engine is both stronger and more affordable than the BMW OEM factory engine, making it the perfect choice for BMW S63 performance enthusiasts. Steve Dinan's engine shop, with 46 years of experience, has built engines that have won numerous championships, including three prototype racing championships and two overall wins in the 24 Hours of Daytona (2011-2013). You won’t find a higher-quality engine from any other BMW tuning company. All engines come with a two-year warranty.
