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

This BorgWarner EFR B1 turbine housing is built with a 63mm compressor wheel and a .85 A/R ratio, designed for serious airflow in forced induction setups. The V-band inlet makes for a clean and secure connection, and the non-wastegated design means you'll need an external wastegate to control boost levels. This housing is a solid choice for builders looking to maximize performance from their turbocharger system.

Constructed from durable cast iron, this housing is made to withstand the high temperatures and pressures found in performance applications. The .85 A/R ratio is a versatile choice, offering a good balance between quick spool-up and high-end power, making it suitable for a wide range of engine builds. Its robust construction means it's ready for the demands of track days or spirited driving.

When installing this turbine housing, ensure you have the appropriate V-band clamp and gasket for a leak-free seal. Because this is a non-wastegated housing, you will need to source and install an external wastegate separately to manage boost pressure effectively. This part is not CARB approved and cannot be shipped to California.
