This genuine BorgWarner EFR B2 Series turbine housing is engineered for high-performance applications that demand a balance between rapid boost response and high-end flow. Designed for the 80mm turbine wheel, the 0.92 A/R ratio provides excellent efficiency for mid-to-high horsepower builds. The T4 twin scroll (divided) inlet configuration is specifically designed to leverage exhaust pulse energy on divided manifold setups for significantly reduced lag.

Built to handle the extreme thermal stresses of racing environments, this housing comes as a complete wastegate assembly (WG Assy) featuring the internal flap mechanism. This ensures precise boost management without the complexity of an external wastegate setup. It is a direct replacement or upgrade for EFR B2 frame turbochargers.
