It is designed to improve 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.\u003c\/p\u003e\n\u003cp data-start=\"529\" data-end=\"1022\"\u003eThe CarBahn B58 engine is both stronger and more affordable than the BMW OEM factory engine, making it the ideal choice for BMW B58 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).
