Both the naturally aspirated MA1.03 and the twin-turbo 9A2 engines offer robust foundations, but building a dedicated track engine demands fortified internal components. Strengthening the rotating assembly with Forged Pistons and Forged Connecting Rods provides the structural integrity required to withstand high compression ratios or elevated boost pressures. Securing these components requires Uprated Engine Bolts (ARP) alongside low-friction Performance Bearings (Conrod & Mains). For engines aiming to maximise volumetric efficiency, Performance Camshafts optimise valve timing. We also supply Misc Engine Parts, providing the required gaskets and seals for complete flat-six overhauls.
