What is the benefit of Ni-Resist material for a turbine housing?

Ni-Resist is a high-nickel cast iron alloy that offers superior resistance to the extreme heat and thermal cycling found in the turbine housing. This durability helps prevent cracking and ensures consistent performance over time.

What does the 0.61 A/R ratio mean for performance?

The A/R ratio influences how quickly the turbocharger spools up. A 0.61 A/R generally promotes faster spooling, which can lead to improved low-end torque and quicker throttle response compared to housings with a higher A/R.

What is a reverse rotation housing and why would I need one?

A reverse rotation housing is designed for turbochargers that spin in the opposite direction of a standard unit. This is typically used in specific twin-turbo setups or custom engine builds where exhaust manifold and plumbing routing necessitates this configuration.

About this part

Product Details

Garrett is well-known for its high-performance turbochargers and components. This GTX3071R Gen II Reverse Turbine Housing Kit is a prime example of their commitment to pushing the boundaries of forced induction technology. It's designed to be a direct replacement or upgrade for specific Garrett turbochargers, allowing you to fine-tune your engine's power delivery and response.

This housing features a 0.61 A/R (Area/Radius) ratio, which is a key factor in determining how quickly the turbocharger spools up and where its power band sits. A lower A/R like this one generally promotes faster spooling, meaning your engine reaches peak boost pressure sooner, which is great for improving low-end torque and throttle response. The Ni-Resist material used in its construction is a type of cast iron known for its excellent resistance to high temperatures and thermal shock, making it ideal for the demanding environment inside a turbine housing. This helps ensure durability and consistent performance even under heavy use.

The kit includes V-band connections for both the turbine inlet and outlet. V-band clamps offer a secure, leak-free seal and make installation and removal simpler compared to traditional bolted flanges. This specific housing is configured for a reverse rotation setup, which is important for certain twin-turbo applications or custom builds where exhaust manifold routing requires it. Please note that this part is not CARB approved and cannot be shipped to California.
