The S63 V8 is a formidable piece of M-division engineering, but pushing this grand tourer into hypercar horsepower territory requires extensive internal fortification. If you are fitting larger hybrid turbochargers to your M6, protecting the block is essential. Safeguard your engine against extreme cylinder pressures using high-strength Forged Pistons and heavy-duty Forged Connecting Rods/Conrods. Lock the rotating assembly down firmly with high-tensile Upgraded Engine Bolts (ARP) and minimize internal friction utilizing race-spec Performance Bearings (Conrod & Mains). Guarantee a leak-free seal with heavy-duty Engine Gaskets, and maximize your top-end breathing capability with Performance Camshafts and Valve Spring Upgrades.
