BorgWarner Turbine Housing EFR B1 58mm .85 V-Band Inlet Single Scroll WG F

This is the BorgWarner EFR B1 turbine housing, featuring a 58mm wheel and a .85 A/R ratio with a V-band inlet. It's designed for single scroll applications and includes an internal wastegate flange. This housing is a key component for building or upgrading a performance turbocharger system, allowing for precise control over exhaust gas flow into the turbine wheel. The .85 A/R ratio is a popular choice for a balance between quick spool-up and high-end power, making it versatile for many engine builds.

Constructed from durable cast iron, this housing is built to withstand the high temperatures and pressures found in forced induction systems. The V-band inlet provides a secure and leak-free connection, simplifying installation and ensuring reliable performance compared to traditional flanged connections. The integrated wastegate port is designed to work with a single wastegate setup, offering effective boost control. This housing is intended for custom turbocharger builds or as a replacement part for existing BorgWarner EFR turbochargers where this specific configuration is required.

Please note that this part is not CARB approved and cannot be shipped to California. It is crucial to verify compatibility with your specific turbocharger core and manifold setup before purchase. For optimal performance and longevity, ensure all connections are properly sealed and the wastegate actuator is correctly set up according to manufacturer specifications.
