hpf Pro Built S54 Engine Shortblocks

After years of building the fastest and most daily driven BMW E46 M3's in the world, we have perfected the optimal balance allowing extreme power (exceeding 1,000rwhp) without compromising daily driveability and fuel economy. These motors are the same engines run in all of our stage 2.5, 2.75, 3 and stage 4 BMW M3s. These motors have our 3rd generation pistons that have been designed to handle extreme long term abuse. The pistons are radiused, deburred and have both side and top coatings. They have special rings that create instant seal upon startup. A super heavy duty grade of wrist pin is used that is not only thick but has incredible wear properties. The wrist pin orifice in the piston was expanded to provide greater wrist pin to piston contact. The connecting rods are extremely burly and are built to handle far in excess of 1,000rwhp. We run factory bearings because they are some of the best you can run. The journals are bore gauged and the exact bearings are selected and installed to provide our propietary bearing clearances. The head is torque plated while the cylinder walls are diamond cut resulting in zero taper. They are also plateau brushed to a mirror finish. This results in zero breakin as the rings seat instantly.
