BorgWarner SuperCore Assembly EFR 9174 Cast Iron Housing

The cast iron housing on this BorgWarner EFR 9174 SuperCore assembly is built to handle the high temperatures and pressures associated with serious performance applications. This unit is designed as a core assembly, meaning it's the heart of a turbocharger system, ready for you to build out with the specific turbine housing and other components that match your engine's needs and your performance goals.

BorgWarner's EFR (Engineered for Racing) line is well-known in the performance world, and the 9174 model is a popular choice for builds aiming for significant power gains. It features advanced aerodynamics and internal components designed for quick spool and sustained boost. The SuperCore assembly includes the center housing rotating assembly (CHRA) with the compressor and turbine wheels, along with the necessary bearings and seals to keep it all running smoothly. This is a substantial piece of hardware, intended for enthusiasts who are serious about maximizing their vehicle's performance.

Because this is a SuperCore assembly, it requires a compatible turbine housing to complete the turbocharger. You'll need to select one that matches your engine's displacement, exhaust flow characteristics, and your desired powerband. This approach allows for a highly customized setup, ensuring the turbocharger is perfectly matched to your specific engine build. Please note that this assembly is not CARB approved and cannot be shipped to California.
