About this part

Product Details

If you're building a custom turbo system or upgrading your existing Garrett GT30R turbocharger, this turbine housing kit is a key component. It controls how exhaust gases flow into the turbine wheel, directly impacting your turbo's spool characteristics and top-end power. This specific housing features a .82 A/R (Area/Radius) ratio, which is a good balance for many performance applications, offering a quicker spool than larger A/Rs while still supporting significant airflow for higher horsepower goals.

Constructed from high-silicon cast iron, this housing is built to withstand the extreme temperatures and pressures found in performance turbocharging. The T4 flange and V-band connection offer a robust and leak-free seal to your exhaust manifold and downpipe, respectively. This kit is designed for the Garrett GT30R series turbochargers, ensuring proper fitment and performance when paired with the correct turbine wheel. The .82 A/R is a popular choice for those looking for improved throttle response over smaller A/Rs without sacrificing too much high-RPM breathing capability.

This kit includes the turbine housing itself. Ensure you have the necessary V-band clamp and gasket for installation. Please note that this part is not CARB approved and cannot be shipped to California.
