The M260 E20 engine block is incredibly robust from the factory, but pushing this platform beyond its factory limits into big-turbo territory requires a fully built engine to handle massive cylinder pressures safely. If you are undertaking a comprehensive engine build, fortifying your bottom end is a necessity. Safeguard your block with high-strength Forged Pistons and heavy-duty Forged Connecting Rods. Lock the rotating assembly firmly in place with high-tensile Uprated Engine Bolts (ARP) and minimize internal drag utilizing race-specification Performance Bearings (Conrod & Mains). Maximize your top-end volumetric efficiency with Performance Camshafts, and finalize your bulletproof motor with our extensive selection of Misc Engine Parts designed for ultimate reliability.
