BorgWarner SuperCore Assembly EFR 8370 Iron

BorgWarner is well-known for its robust and reliable drivetrain components, and their EFR (Engineered for Racing) line of turbochargers continues that legacy. This is the EFR 8370 SuperCore assembly, built with an iron turbine housing for durability and heat resistance in demanding applications. It’s designed as a core assembly, meaning it’s the heart of the turbocharger ready for custom plumbing and mounting.

The EFR 8370 is a popular choice for tuners and builders looking to significantly increase horsepower. It features advanced aerodynamics for quick spool and broad powerband, helping your engine breathe easier and make more power across the RPM range. The internal wastegate is integrated into the turbine housing, simplifying plumbing and ensuring precise boost control. This assembly is built to handle the stresses of high-performance use, making it a solid foundation for a custom turbo setup.

Because this is a SuperCore assembly, it requires custom fabrication for installation, including exhaust manifold connection, intake piping, and oil/coolant lines. It is not CARB approved and cannot be shipped to California. Please consult your installer or fabrication specialist to ensure proper integration with your specific vehicle and engine build.
