The EA888 Gen 4 (Evo4) 2.0-litre turbocharged engine is an engineering marvel, but extracting extreme horsepower levels requires a heavily reinforced internal architecture. High-boost applications generate immense cylinder pressures that can quickly expose the limits of factory bottom-end components. Fortify your TSI block with our premium selection of Forged Pistons and heavy-duty Forged Connecting Rods/Conrods. Secure your rotating assembly with high-tensile Upgraded Engine Bolts (ARP) and drastically reduce internal friction with race-spec Performance Bearings (Conrod & Mains). Ensure a perfect, leak-free seal on your high-performance engine build with upgraded Engine Gaskets.
