What is the A/R ratio and why does it matter?

The A/R ratio, or area-to-radius ratio, on a turbine housing describes the size of the exhaust housing. A 0.83 A/R ratio indicates a moderate-sized housing that balances exhaust flow and turbine wheel speed, affecting boost response and peak power potential.

What does 'reverse rotation' mean for a turbocharger?

Reverse rotation refers to the direction the turbocharger's turbine wheel spins. This housing is specifically designed to work with a G30 turbocharger core that spins in the reverse direction, which is important for certain twin-turbo setups or specialized applications.

What are the benefits of a V-band connection?

V-band connections use a clamp to secure two flanged pieces together, creating a strong and leak-free seal. They are often preferred over traditional bolt-on flanges because they are easier to install and remove, and they can accommodate slight thermal expansion and contraction.

Product Details

Garrett is well-known for their high-performance turbochargers, and this G30 Turbine Housing Kit is a prime example of their commitment to forced induction technology. This specific kit is designed for reverse rotation applications, featuring a V-band inlet and outlet for a secure and leak-free seal. The 0.83 A/R (area-to-radius) ratio is carefully chosen to balance exhaust gas flow with turbine speed, helping to optimize boost response and overall power delivery for your performance build.

This housing is constructed from durable cast iron, a material chosen for its ability to withstand the high temperatures and pressures found in exhaust systems. The V-band connections simplify installation and removal compared to traditional flanged setups, making it easier to work on your turbo system. This kit is intended for enthusiasts looking to fine-tune their turbocharger's performance characteristics, offering a specific A/R ratio that works well for a wide range of engine displacements and power goals when paired with the appropriate G30 turbocharger core.

When considering this turbine housing, remember that it is not CARB approved and cannot be shipped to California. It's essential to ensure this component aligns with your specific turbocharger model and overall engine build strategy to achieve the desired performance outcomes. Proper installation and tuning are critical for maximizing the benefits of this high-performance component.
