Regular price $13,217.00 USD
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. Most of the cores we receive arrive with a spun rod bearing and we price this engine rebuild accordingly. Due to the metal that has gone through the motor we provide a new BMW oil pump. We also count on replacing one rod with a used BMW rod and rebalancing the set of 6 rods together. We pull out all plugs to completely clean out all the oil galleys.

We repair the crankshaft in this repair and it is typically welded, heat treated, nitrided and fully balanced. Bearings are selected as needed for ideal main and rod bearing clearance. Depending on availability and application we will either use CP Pistons or Mahle Powerpak pistons. Our go to size is 87.25mm so we can do a second rebuild down the road on the same block.

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.

  • Genuine BMW rod bolts, ACL rod bearings, ACL main bearings, main bolts, head gasket set and main engine gasket set including all O rings and seals, and all timing chain and oil pump guide rails.
