What does the .62 A/R rating mean for performance?

The .62 A/R (area-to-radius ratio) rating on this turbine housing indicates the size of the exhaust gas passage. A smaller A/R like .62 generally helps the turbocharger spool up faster, improving throttle response at lower RPMs, while still allowing for good airflow at higher engine speeds.

What is the benefit of an internal wastegate (IWG)?

An internal wastegate is built directly into the turbine housing. This simplifies the plumbing and installation compared to external wastegates, as it manages boost pressure internally without requiring separate components and external plumbing.

Can this turbine housing be shipped to California?

No, this turbine housing is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

TiAL Sport is well-known for making high-performance turbocharger components, and this GT35 stainless steel turbine housing is a prime example of their work. This housing is designed for the GT35-style turbocharger and features a .62 A/R (area-to-radius ratio) which helps to optimize airflow for a balance of quick spool and top-end power. The integrated internal wastegate (IWG) simplifies setup by controlling boost pressure directly within the housing.

Constructed from durable stainless steel, this turbine housing is built to withstand the extreme temperatures and pressures found in high-performance forced induction systems. The .62 A/R is a popular choice for many applications looking for improved throttle response over larger A/R housings, while still allowing for significant airflow at higher RPMs. This housing is a direct replacement for GT35-style turbos and is designed to bolt up with minimal modification, assuming the rest of your turbo system is configured correctly.

When installing this turbine housing, ensure you have the appropriate gaskets and hardware for a leak-free seal. Because this part is not CARB approved, it cannot be shipped to California. Always consult your turbo manufacturer's specifications and local emissions regulations before installation.
