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

This BorgWarner EFR B1 turbine housing features a 58mm compressor wheel and a .85 A/R (area to radius) ratio, which helps manage exhaust gas flow for optimal turbocharger performance. The V-band inlet connection offers a secure and leak-free seal, simplifying installation compared to traditional flanged connections. This single scroll, non-wastegated design is built for applications where precise boost control is managed externally, allowing for a more direct exhaust path and potentially improved spool characteristics.

Constructed from durable cast iron, this housing is designed to withstand the high temperatures and pressures associated with exhaust gases. The 58mm wheel size is a popular choice for a wide range of performance builds, offering a good balance between quick spool-up and top-end power. Its .85 A/R ratio is well-suited for engines that need to breathe efficiently at higher RPMs while still providing a responsive feel off the line. The V-band inlet means you'll need a compatible V-band clamp and flange on your exhaust manifold or downpipe, ensuring a solid connection that can handle vibration and thermal expansion.

This turbine housing is a key component for anyone building or upgrading a forced induction system. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to your specific application's requirements and consult with a professional when selecting and installing turbocharger components to ensure proper fitment and performance.
