Stage 2 S58 High Performance Engine | BMW G8X M2/M3/M4 RWD

The CarBahn ST2 S58 engine is rated for up to 850 lb-ft of torque. It is designed to enhance durability for high-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. Please note, the engine itself is not covered under warranty. 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 CarBahn engine is both stronger and less expensive than the BMW OEM factory engine. The S58 CarBahn engine is designed to improve the strength of your engine if you are tuning your car. Connecting rods are replaced with Carrillo forged racing rods. Pistons are CP forged racing pistons. The engine also comes with ported cylinder head and high-performance valve springs for ultra-high boost pressures. The engine is a complete overhaul with blue printing and balancing. This engine is designed for an increase in torque of 100% over stock.
