What is Ni-Resist cast iron and why is it used for this housing?

Ni-Resist is a high-nickel cast iron alloy chosen for its superior thermal stability and resistance to heat checking and cracking. This is crucial for turbine housings that experience extreme exhaust gas temperatures.

What does the 1.01 A/R ratio mean for performance?

The A/R ratio (Area/Bypass ratio) indicates the size of the turbine housing's internal passages. A larger A/R like 1.01 generally allows for better exhaust gas flow at higher RPMs, which can help the turbocharger sustain boost and produce more peak horsepower.

What are the advantages of V-band connections?

V-band connections use a clamp to secure two flanged ends together, creating a strong, leak-free seal. They are often preferred for their ease of installation and removal compared to traditional bolted flanges, and they can handle higher pressures and temperatures.

About this part

Product Details

If you're building a custom turbo system or looking to fine-tune your existing setup for more top-end power, this Garrett GTX3017R Gen II reverse turbine housing is a key component. It's designed to work with the GTX3017R Gen II turbocharger, allowing you to tailor the exhaust flow characteristics to your specific engine and performance goals. The reverse rotation design is often used in twin-turbo applications or where packaging constraints require a specific compressor and turbine orientation.

This housing is cast from Ni-Resist, a high-nickel cast iron alloy known for its excellent thermal stability and resistance to heat checking and cracking, even under extreme exhaust temperatures. The 1.01 A/R (Area/Bypass ratio) is on the larger side, which generally helps improve exhaust gas flow at higher RPMs, allowing the turbo to spool more efficiently and sustain boost levels further into the powerband. This makes it a good choice for builds focused on maximizing horsepower, especially in applications where the engine can effectively utilize the increased flow. The V-band inlet and outlet connections offer a strong, leak-free seal and simplify installation and removal compared to traditional flanged connections.

This kit includes the reverse turbine housing and is designed for direct fitment onto the Garrett GTX3017R Gen II turbocharger. Please note that this part is not CARB approved and cannot be shipped to California. Always consult your turbocharger manufacturer's installation guide for specific fitment and assembly instructions.
