BorgWarner Turbine Housing EFR B2 64mm .83 T3 Single Scroll WG Assy

If you're looking to build a custom turbo system or upgrade an existing one for improved performance, a well-chosen turbine housing is key. This BorgWarner EFR B2 turbine housing is designed for serious performance builds, offering a .83 A/R ratio in a T3 flange configuration with a single scroll wastegate setup. This specific housing is built to handle significant airflow, making it a solid choice for those aiming for increased horsepower and quicker turbo spool.

The EFR (Engineered for Racing) line from BorgWarner is known for its robust construction and performance-oriented design. This housing features a 64mm inducer diameter, which balances responsiveness with the ability to support higher power levels. The .83 A/R (area-to-radius) ratio is a popular choice for many applications, providing a good compromise between low-end torque and high-end power. Its T3 flange makes it compatible with a wide range of turbochargers and exhaust manifolds, and the single scroll design simplifies setup for many custom turbo applications. This housing is constructed from durable materials designed to withstand the high temperatures and pressures found in forced induction systems.

When planning your build, remember that this turbine housing is not CARB approved and cannot be shipped to California. It's important to ensure this housing matches your turbocharger's compressor cover and your overall engine build goals for optimal performance. Proper exhaust manifold selection and wastegate control are crucial for getting the most out of this component.
