BorgWarner Turbine Housing EFR B1 63mm .85 VOF V-Band Inlet WG

This is the BorgWarner EFR B1 turbine housing, featuring a 63mm wheel size and a .85 A/R ratio. It's designed with a V-band inlet and a wastegate (WG) port, making it a key component for high-performance forced induction setups. This housing is built to handle demanding applications where precise boost control and efficient exhaust gas flow are critical for maximizing engine power. Its construction is geared towards durability and consistent performance under stress.

The .85 A/R (Area/Radius) ratio on this housing is a notable specification, influencing how quickly the turbocharger spools up and at what engine RPM it reaches its peak efficiency. A larger A/R like .85 generally allows for better flow at higher engine speeds, helping to prevent backpressure and maintain power delivery in the upper RPM range. The V-band inlet is a practical feature, offering a secure and easy-to-seal connection compared to traditional flanged setups, which simplifies installation and maintenance. This housing is intended for use with the EFR series of turbochargers, known for their advanced design and robust build.

When considering this turbine housing, it's important to note that it is not CARB approved and therefore cannot be shipped to California. This is a component for custom or performance-oriented builds where specific turbocharger characteristics are desired. Ensure compatibility with your existing turbocharger core or intended build specifications before purchase. This part is sold individually.
