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

The .62 A/R ratio refers to the turbine housing's flow characteristics. A smaller A/R like .62 generally helps the turbocharger spool up faster at lower RPMs, providing quicker throttle response. It's a common choice for a balanced setup that doesn't sacrifice too much top-end power.

Why is water cooling important for the wastegate?

Water cooling helps to dissipate heat from the internal wastegate actuator. This can lead to more consistent boost control over time, as extreme temperatures can affect the performance and longevity of the wastegate components.

What materials is this turbine housing made from?

This turbine housing is constructed from stainless steel. This material is chosen for its ability to withstand the high temperatures and corrosive environment of exhaust gases found in forced induction applications.

Product Details

This stainless steel turbine housing from TiAL Sport is built with a .62 A/R ratio and features water cooling for its internal wastegate (IWG). The A/R ratio, which is the area of the turbine outlet divided by the radius to the center of the volute, directly impacts how quickly the turbocharger spools up and how much boost it can produce at higher RPMs. A .62 A/R is a popular choice for a balanced performance profile, offering a good compromise between low-end response and top-end power for many GT35-based turbocharger setups.

Constructed from durable stainless steel, this housing is designed to withstand the high temperatures and pressures generated by exhaust gases. The water-cooling feature for the internal wastegate helps to regulate temperature, which can improve the longevity of the wastegate actuator and ensure more consistent boost control. This housing is specifically designed to mate with GT35-style turbocharger wheels, making it a key component for building or upgrading a forced induction system where precise control and robust materials are important.

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 refer to the manufacturer's installation instructions for specific details regarding fitment and assembly.
