What is the A/R ratio and why is it important?

The A/R ratio (Area/Radius) on a turbine housing measures the flow capacity of the housing. A 0.57 A/R, like on this housing, typically offers a good compromise between how quickly the turbo spools up and how much power it can make at higher engine speeds.

What are the benefits of Ni-Resist material?

Ni-Resist is a special type of iron alloy that is very strong at high temperatures and resists cracking from repeated heat cycles. This makes it ideal for the demanding environment inside a turbocharger's turbine housing.

What type of connections does this housing use?

This turbine housing uses V-band connections for both the exhaust inlet and the turbine outlet. V-band connections create a strong, reliable seal and are often easier to install and remove than traditional bolted flanges.

Product Details

Garrett is well-known for their advanced turbocharger technology, and this GT28R Turbine Housing Kit is a prime example of their commitment to performance. This specific housing is designed for the GT28R turbocharger, featuring a 0.57 A/R ratio. The A/R (Area/Radius) ratio is crucial because it dictates the airflow characteristics of the turbine housing; a 0.57 A/R generally offers a good balance between quick spool-up and top-end power for many applications.

What sets this housing apart is its construction from Ni-Resist, a type of ductile iron alloy known for its excellent high-temperature strength and resistance to thermal fatigue. This material is vital for turbocharger components that endure extreme heat cycles. The housing utilizes V-band connections for both the inlet and outlet, which provides a strong, leak-free seal and simplifies installation compared to traditional flanged connections. This kit is intended for enthusiasts looking to fine-tune their turbocharger's performance characteristics or replace a worn housing on their existing GT28R unit.

When installing this turbine housing, ensure you have the appropriate V-band clamps and gaskets to achieve a proper seal. Because this part is not CARB approved, it cannot be shipped to California. Always refer to your turbocharger's specific service manual for detailed installation procedures and torque specifications.
