TiAL Sport BWVB3745-102 A/R 83.5mm S400 Stainless Steel Turbine Housing

TiAL Sport is well-known for making high-performance turbocharger components, and this S400 stainless steel turbine housing is a prime example of their work. This housing, with an A/R ratio of 83.5mm, is designed to fit S400-frame turbochargers and is built from durable stainless steel to handle the extreme temperatures and pressures found in demanding engine applications.

The choice of stainless steel for the turbine housing is notable because it offers excellent resistance to corrosion and thermal fatigue, which are common issues in high-heat exhaust environments. This material selection contributes to the longevity and reliability of the component, ensuring it can withstand repeated heat cycles without degrading. The 83.5mm A/R ratio is a specific airflow characteristic that influences how quickly the turbocharger spools up and at what engine speeds it reaches peak efficiency. This particular ratio is often chosen for builds aiming for a balance between responsive low-end performance and strong top-end power delivery, making it a versatile option for many custom turbo setups.

When installing a turbine housing like this, it's important to ensure all mating surfaces are clean and that proper gasket material is used to prevent exhaust leaks. This housing is designed as a direct replacement for compatible S400 turbos, simplifying the installation process for mechanics and enthusiasts alike. Please note that this part is not CARB approved and cannot be shipped to California due to emissions regulations.
