The 2.3-litre EcoBoost is a highly potent engine, but pushing for massive horsepower requires a strengthened bottom end to handle extreme cylinder pressures. Safely push the limits of your RS Mk3 by installing heavy-duty Forged Conrods and fully Forged Pistons. Secure your block with high-tensile Engine Bolts, race-spec Engine Bearings, and high-pressure Engine Gaskets. Replace fragile factory lines with durable silicone Engine Hoses, and complete your custom engine assembly with our wide range of Misc Engine Parts designed for fully forged 2.3 builds.
