The B58 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 lowered compression, 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.\u003c\/p\u003e\n\u003cp\u003eSteve Dinan’s engine shop has been building racing engines for 43 years. Those engines have won many championships including three prototype racing championships including 2 overall wins in the 24hrs of Daytona in 2011-2013. You will not find a higher quality engine. All engines are backed with a two-year warranty.\u003c\/p\u003e","brand":"CarBahn","offers":[{"title":"Default Title","offer_id":44404816347344,"sku":"CBB58-6208","price":15995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0633\/5886\/1520\/files\/CB058-6001-1120x9605-1_ad9f9031-094c-4b75-a75e-11b261a96e59.jpg?v=1738241678","url":"https:\/\/motorworkswest.shop\/products\/stage-2-b58-high-performance-engine-b30b-awd-bmw-540i-m240i-m340i-m440i-x3m40i-x4m40i","provider":"Motor Works West","version":"1.0","type":"link"}
