BorgWarner Turbine Housing SX S400 A/R 1.00

This is the BorgWarner Turbine Housing for the S400 series turbocharger, part number 176810. It features a 1.00 A/R ratio, which is a key specification that dictates how efficiently exhaust gases flow from your engine into the turbocharger's turbine wheel. A larger A/R like this one generally means better flow at higher engine speeds, helping your turbo spool up effectively and maintain boost in the upper RPM range.

Built by BorgWarner, a well-known name in turbocharger technology, this housing is made to handle the demanding conditions of forced induction. The cast iron construction is solid and designed to withstand high temperatures and pressures. When you're looking to fine-tune your turbo's performance, especially for applications that see a lot of time at higher RPMs, changing the turbine housing is a common and effective way to alter the boost characteristics.

Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to your specific turbocharger build and engine tuning requirements when selecting a turbine housing.
