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 high performance valve springs for increased boost. The engine is a complete overhaul with blue printing and balancing. This engine is designed for an increase in torque of 50% over stock.
