TiAL Sport BWVB3745-145 A/R 87.35mm S400 Stainless Steel Turbine Housing

This package includes the TiAL Sport BWVB3745-145 turbine housing, designed for S400-style turbochargers. It features a specific A/R ratio of 0.87 and a 3.74 inch (95mm) turbine outlet diameter, making it a well-built component for those looking to customize or upgrade their forced induction setup. The stainless steel construction is chosen for its ability to withstand high temperatures and resist corrosion, which is crucial in the demanding environment of a turbo system.

The 87.35mm A/R ratio is a key specification that influences how quickly the turbocharger spools up and how much boost it can efficiently produce at higher RPMs. A lower A/R generally leads to quicker spool, while a higher A/R can help maintain boost at higher engine speeds. This particular housing is intended for use with S400-style turbos, offering a direct replacement or upgrade path for specific applications. Its robust stainless steel build means it's made to handle the heat cycles and exhaust gas flow associated with performance tuning.

When installing a new turbine housing, it's important to ensure proper mating surfaces are clean and that all connections are sealed correctly to prevent exhaust leaks. This housing is not CARB approved and therefore cannot be shipped to California. Always consult your turbocharger manufacturer's specifications and a qualified installer to confirm compatibility with your specific turbocharger and engine build.
