The CarBahn ST1 S58 engine is rated for up to 750 lb-ft of torque. It is designed to enhance durability for medium-output tunes, making it an excellent alternative to an OEM factory remanufactured engine, especially if your original engine has failed and is no longer under warranty. We use high-quality racing components, including Carrillo connecting rods, forged CP pistons, high-performance valve springs, and a high-performance head gasket. This engine maintains the stock compression ratio, ensuring exceptional drivability and fuel economy. The CarBahn S58 engine is both stronger and more affordable than the BMW OEM factory engine, making it the perfect choice for BMW S58 performance enthusiasts.
Steve Dinan's engine shop, a renowned BMW tuning company with 46 years of experience, has built engines that have won multiple 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.
