The CarBahn ST3 B58 engine is rated for 1,000+ lb-ft of torque and is designed for ultra-high output tunes. We use premium racing components like Carrillo connecting rods, forged CP pistons, high-performance valve springs, ultra-high-performance head gaskets, cylinder head studs, and racing camshafts. The engine lowers compression by 0.5 to enable more power with higher boost settings without detonation issues.
The CarBahn B58 engine is stronger and more affordable than the BMW OEM factory engine, making it an excellent choice for 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 anywhere else. All engines come with a two-year warranty.
