Regular price Sale price $13,217.00 USD

This engine is the most popular racing engine for BMW powered cars in club racing right now and we use them in several cars. This long block assembly meets our stringent requirements for our own race cars and is the perfect solution to replace your worn out S54. Drawing on our experience racing these engines and seeing their common problems and failures we go through your supplied core engine and replace all wear items. We also remove the cylinder head and have it replaned, dissassembled, cleaned, inspected, do our Stage 1 cylinder head 5 angle valve job with new seals and do a proper reinstallation. From there we will do a valve adjustment with the engine on the stand and reseal the valve cover. We also give your VANOS a full Beisan Systems treatment.

Our engines are guaranteed to pass leakdown tests with less than 3% on all cylinders, most often cylinders will be at 1-2% leakdown on all cylinders when tested at our facility before being sent out.
