FAQ
What turbochargers use the BorgWarner 176812 turbine housing?
The 176812 is commonly used on BorgWarner AirWerks S400 turbochargers utilizing an 83mm turbine wheel. Always verify turbine wheel dimensions before purchasing.
What does the 1.25 A/R ratio provide?
A larger 1.25 A/R housing typically improves top-end airflow and helps reduce drive pressure in high-horsepower applications, making it popular for competition and racing builds.
Is this housing compatible with T4 manifolds?
No. The BorgWarner 176812 utilizes a T6 turbine inlet flange and requires a compatible T6 exhaust manifold.
Can this housing be used in compound turbo systems?
Yes. The 176812 is commonly used in compound turbocharger systems where maximizing exhaust flow and efficiency is important.
Is this a genuine BorgWarner component?
Yes. The 176812 is a genuine BorgWarner AirWerks replacement turbine housing manufactured to factory specifications.
Why upgrade to a larger turbine housing?
Larger turbine housings can help reduce exhaust backpressure, improve high-RPM airflow, and support higher horsepower levels when properly matched to the turbocharger and engine combination.
