Both the M156 and M157 V8 engines are masterpieces of Affalterbach engineering, but pushing this platform into hypercar-baiting territory requires a fully reinforced bottom end to safely handle monumental cylinder pressures. Safeguard your block against extreme forced induction or high-rpm stress with high-strength Forged Pistons and heavy-duty Forged Connecting Rods. Lock the rotating assembly down firmly using high-tensile Uprated Engine Bolts (ARP) and minimize internal friction utilizing race-specification Performance Bearings (Conrod & Mains). Maximize your cylinder head airflow with Performance Camshafts, and finalize your bulletproof motor with our selection of Misc Engine Parts designed for ultimate reliability.
