What is the A/R ratio, and what does 0.61 mean for my turbo?

The A/R ratio (Area/Radius) on a turbine housing measures the cross-sectional area of the housing relative to the radius to the center of the housing. A lower A/R ratio, like 0.61, generally means the housing is smaller, which helps the turbocharger spool up faster and provides better boost response at lower engine RPMs.

What are the benefits of V-Band connections?

V-Band connections use a clamp system to secure the housing, offering a strong, leak-free seal that is often more reliable than traditional bolted flanges. They also make installation and removal simpler, as you don't need to deal with gaskets or torque sequences in the same way.

Is this turbine housing compatible with all Garrett turbochargers?

This specific turbine housing is designed for the Garrett G30 series turbochargers. It is important to verify that your existing G30 turbocharger uses O/V V-Band connections and is intended to be paired with a 0.61 A/R housing for optimal performance.

Product Details

This kit includes the Garrett G30 Turbine Housing, designed for O/V V-Band connections with a 0.61 A/R ratio and standard rotation. This component is crucial for managing exhaust gas flow into the turbocharger's turbine wheel, directly impacting boost response and overall engine performance. It's a well-built piece from Garrett, a name known for reliable forced induction components.

The 0.61 A/R (Area/Radius) ratio is a key specification that influences how quickly the turbocharger spools up. A smaller A/R like this one generally leads to quicker spool and improved low-end response, making it suitable for applications where rapid boost delivery is desired. The V-Band connections offer a strong, leak-free seal and simplify installation and removal compared to traditional flanged setups. This housing is intended for use with Garrett's G30 series turbochargers, ensuring proper fitment and performance integration within that system.

When considering a turbine housing upgrade or replacement, it's important to match the A/R ratio and connection type to your specific engine build and performance goals. This Garrett housing is a solid option for those looking to fine-tune their turbo system's characteristics. Please note that this part is not CARB approved and cannot be shipped to California.
