What is the benefit of a 0.72 A/R turbine housing?

A 0.72 A/R (Area to Radius) ratio generally allows for better exhaust gas flow at higher RPMs. This can result in improved top-end horsepower compared to housings with smaller A/R ratios, which tend to spool faster but may limit peak power.

What is Ni-Resist material?

Ni-Resist is a family of nickel-chromium-iron alloys known for their excellent resistance to high temperatures and thermal fatigue. This makes it a durable material choice for the hot side of a turbocharger, helping to prevent cracking under extreme conditions.

What is included in this kit?

This kit includes the Garrett GT28R turbine housing. You will need to source appropriate V-band clamps and gaskets separately to ensure a proper seal upon installation.

Product Details

If you're looking to fine-tune the performance of your Garrett GT28R turbocharger, swapping out the turbine housing is a common and effective way to change how the turbo spools and delivers power. This specific housing is designed for the GT28R model and features a 0.72 A/R ratio, which generally helps improve top-end power by allowing exhaust gases to flow more freely at higher RPMs compared to smaller A/R housings. The V-band inlet and outlet connections make for a secure and easy installation, simplifying the process of integrating it into your existing exhaust and downpipe setup.

Constructed from Ni-Resist, a type of ductile iron, this housing offers excellent resistance to high temperatures and thermal shock. This material choice is crucial for durability in the demanding environment of a turbocharger's exhaust side, helping to prevent cracking and ensuring a longer service life. The 0.72 A/R ratio is a popular choice for builds aiming for a balance between quick spool and strong peak horsepower, often found in applications where the engine displacement and overall airflow demands are moderately high. This housing is designed to bolt directly onto the Garrett GT28R turbine wheel, ensuring proper fitment and sealing.

This kit includes the turbine housing itself. When installing, ensure you have the appropriate V-band clamps and gaskets for both the inlet and outlet to achieve a proper seal. It's important to note that this part is not CARB approved and cannot be shipped to California due to emissions regulations.
