BorgWarner Turbine Housing EFR B2 70mm .83 T3 Single Scroll WG Assy

What you get with this BorgWarner EFR B2 turbine housing is a precisely cast component designed to optimize exhaust flow for a specific turbocharger setup. This particular housing features a 70mm inducer diameter and a .83 A/R ratio, paired with a T3 inlet flange and a single scroll wastegate port. It's built for enthusiasts looking to fine-tune their forced induction system for improved spool characteristics and top-end power.

The EFR (Engineered for Racing) line from BorgWarner is known for its robust construction and performance-oriented design. This housing is made from a high-grade cast iron material that can handle the extreme temperatures and pressures found in performance turbo applications. The .83 A/R ratio is a good balance, offering a noticeable improvement in boost response over larger A/R housings while still allowing the turbo to breathe effectively at higher RPMs. The T3 inlet flange is a common size, making it compatible with a wide range of aftermarket turbo manifolds, and the single scroll wastegate setup is straightforward for managing boost levels.

When considering this turbine housing, remember it's a component for a larger turbocharger assembly. You'll need to ensure it mates correctly with your chosen BorgWarner EFR center section and exhaust manifold. This part is not CARB approved and cannot be shipped to California due to emissions regulations.
