BorgWarner Turbine Housing EFR B1 58mm .64 T25 Single Scroll WG Assy

This BorgWarner EFR B1 turbine housing is built around a 58mm compressor wheel and features a .64 A/R (area-to-radius) ratio. This specific A/R is a key factor in how quickly the turbocharger spools up and how much boost it can generate at lower engine speeds. The T25 flange makes it compatible with a range of turbocharger setups, and the single scroll wastegate assembly is integrated directly into the housing for a more compact and efficient design. This housing is designed for performance applications where precise control over boost response is critical.

Constructed from durable cast iron, this turbine housing is made to withstand the high temperatures and pressures found in forced induction systems. The material choice ensures longevity and consistent performance even under demanding conditions. BorgWarner is known for its robust turbocharger components, and this housing is no exception, offering a well-built solution for enthusiasts looking to optimize their turbo system's performance. The .64 A/R is a popular choice for achieving a balance between quick spool-up and top-end power, making it versatile for various engine builds.

When installing this turbine housing, ensure you have the correct gaskets for the T25 flange and the wastegate assembly to prevent exhaust leaks, which can significantly impact performance and turbo longevity. It's also important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation guide for specific torque values and procedures to ensure a proper and safe installation.
