While the 3.0-litre N55 engine is a fantastic platform, pushing into big-turbo horsepower figures requires a reinforced internal architecture to withstand extreme cylinder pressures. Protect your inline-six block and prepare for massive boost by upgrading to high-strength Forged Pistons and heavy-duty Forged Connecting Rods/Conrods. Lock your rotating assembly firmly in place with high-tensile Upgraded Engine Bolts (ARP) and minimize internal friction using race-specification Performance Bearings (Conrod & Mains). Ensure a completely leak-free seal across the engine block and cylinder head with our heavy-duty Engine Gaskets.
