Stage 1 B58 High Performance Engine (B30A AWD)

The CarBahn B58 engine is designed to boost the strength and performance of your BMW engine, particularly for tuning applications. Rated for up to a 50% increase in torque over stock, this engine upgrade features Carrillo forged racing rods, CP forged racing pistons, and high-performance valve springs to handle higher boost levels. The engine also undergoes blueprinting and balancing to ensure optimal performance and reliability.

CarBahn's B58 performance engine offers a stronger and more affordable alternative to the BMW OEM factory engine, providing exceptional durability for high-performance tunes. Backed by Steve Dinan’s 46 years of experience in building championship-winning racing engines, including multiple victories at the 24 Hours of Daytona, this engine is engineered for maximum reliability and power. The CarBahn BMW B58 engine tuning is both stronger and more affordable than the BMW OEM factory engine. 

All CarBahn engines are backed by a two-year warranty and are built to the highest standards. To ensure the best quality, the core must be a complete factory engine (from oil pan to valve cover) and meet specific acceptance criteria.
