This BorgWarner turbine housing is designed for the S400 series turbocharger, featuring an A/R ratio of .90. This specific housing is a replacement part that allows you to tune your turbocharger's performance. The A/R ratio influences how quickly the turbocharger spools up and how much boost it can produce at higher engine speeds.

Crafted by BorgWarner, a well-known name in forced induction components, this turbine housing is built to handle the demands of performance applications. Its construction aims for durability and consistent performance, ensuring it can withstand the high temperatures and pressures found in the exhaust stream. This part is intended to fit directly onto compatible S400 turbocharger assemblies, making it a straightforward replacement if your current housing is damaged or if you're looking to change your turbo's characteristics.
