Product Details

What you get with this order is a TiAL Sport BWVB3745-116 turbine housing, specifically designed for S400-style turbochargers. This housing features an A/R ratio of 0.87 and a 3.74-inch (95mm) outlet diameter, with a 4.5-inch (114.3mm) V-band inlet. It's constructed from durable stainless steel, which is known for its resistance to corrosion and ability to handle high exhaust temperatures.

This turbine housing is a key component for anyone looking to build or upgrade a high-performance forced induction system. The stainless steel construction means it can withstand the harsh conditions found in a turbocharger's exhaust path, helping to ensure longevity and consistent performance. The specific A/R ratio of 0.87 is chosen to balance quick turbo spool-up with the ability to make good power at higher RPMs, making it a popular choice for a wide range of applications where both responsiveness and top-end flow are important. The 3.74-inch outlet with a 4.5-inch V-band connection makes it compatible with many common exhaust dump tubes and downpipe setups for S400 turbos.

Please be aware that this part is not CARB approved and cannot be shipped to California. Always refer to your local emissions regulations before purchasing and installing aftermarket performance parts.
