The hand-built AMG engine block is incredibly robust from the factory, standing as one of the most powerful production four-cylinders of its generation. However, pushing this platform well beyond its factory limits into big-turbo territory requires a fully built engine to handle the monumental cylinder pressures safely. 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 selection of Misc Engine Parts designed to complete your ultimate engine build.
