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

The A/R ratio (Area/Radius) of a turbine housing affects how the turbocharger performs. A lower A/R, like the 0.61 in this housing, generally leads to faster spool-up and better response at lower engine RPMs. A higher A/R typically provides more top-end power but can result in slower initial boost.

What does 'reverse rotation' mean for a turbocharger?

Reverse rotation refers to the direction the turbocharger's turbine wheel spins. Most turbos spin clockwise, but some applications, especially twin-turbo setups or specific engine designs, require a counter-clockwise (reverse) rotation. This housing is specifically made for those reverse rotation G35 turbos.

What are the benefits of V-band connections?

V-band connections use a clamp and a grooved flange to create a seal. They are known for being very secure, leak-resistant, and easier to install or remove than traditional bolted flanges. This makes maintenance and assembly of your turbo system more straightforward.

About this part

Product Details

This Garrett G35 Turbine Housing Kit gives you the specific housing needed for your G35 turbocharger, featuring an Open/V-Band inlet and V-Band outlet. It's designed for reverse rotation applications, meaning it's intended for setups where the turbo spins counter-clockwise. The housing has a 0.61 A/R ratio, which influences how quickly the turbo spools up and its efficiency at different engine speeds. A lower A/R like this generally leads to quicker boost response, making it suitable for smaller displacement engines or applications prioritizing low-end torque.

Garrett is well-known in the performance world for their turbochargers, and this housing is built to their standards. It's made from a durable cast iron material that can handle the high temperatures and pressures found in a turbo system. The V-band connections on both the inlet and outlet offer a secure and leak-free seal, and they also make installation and removal simpler compared to traditional flanged setups. This housing is a key component for anyone building or rebuilding a custom turbo system for their vehicle, especially when aiming for a specific performance profile that benefits from a responsive turbocharger.

Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to your specific turbocharger build plans and consult with a professional if you have questions about compatibility or installation. This housing is designed to work with the Garrett G35 series turbochargers.
