The 3.8-litre flat-six is a highly durable power plant, but increasing displacement or constructing a high-compression race engine demands fortified internal hardware. Strengthening the engine block with Forged Pistons and Forged Connecting Rods provides the durability required to withstand intense cylinder pressures. Keeping the rotating assembly secure at high engine speeds requires Uprated Engine Bolts (ARP) alongside low-friction Performance Bearings (Conrod & Mains). For owners seeking maximum top-end power, installing Performance Camshafts improves cylinder head airflow. We also supply Misc Engine Parts covering the essential gaskets and seals necessary for a complete engine rebuild.
