What is the purpose of the .80 A/R ratio on this turbine housing?

The .80 A/R ratio refers to the area-to-radius ratio of the turbine housing's volute. A lower A/R like .80 generally helps the turbocharger spool up faster, improving throttle response and low-end power delivery. It balances this with the ability to still support significant top-end power.

Why is the water-cooled feature important for this turbine housing?

The water-cooling feature helps dissipate heat from the area around the internal wastegate actuator. This can lead to more stable and consistent boost pressure control, especially during prolonged high-load operation, and may contribute to the longevity of the wastegate components.

What does 'Not CARB approved' mean for this product?

This means the turbine housing does not meet the emissions standards set by the California Air Resources Board (CARB). As a result, it cannot be legally sold or shipped to California for use on emissions-controlled vehicles in that state.

Product Details

This is the TiAL Sport GT35 stainless steel turbine housing, specifically the .80 A/R version with a water-cooled internal wastegate (IWG) setup. It's designed to be a direct replacement or upgrade for turbochargers using the GT35 footprint, allowing you to fine-tune your turbo system's performance characteristics. The A/R ratio, or area-to-radius ratio, of .80 influences how the exhaust gases flow through the turbine wheel. A lower A/R like this one generally helps the turbo spool up faster, improving low-end response, while still supporting good top-end power.

Constructed from durable stainless steel, this housing is built to withstand the high temperatures and pressures found in the exhaust stream. The water-cooling feature helps manage heat around the wastegate actuator, which can lead to more consistent boost control and potentially extend the life of the wastegate components. This housing is intended for use with GT35-style turbochargers and is a popular choice for those looking to build or refine a custom forced induction system where precise control and reliable operation are key. It's important to note that this part is not CARB approved and cannot be shipped to California.

When installing this turbine housing, ensure you have the correct mating flange for your specific turbocharger and exhaust manifold. Proper sealing is critical to prevent exhaust leaks. It's also recommended to use new hardware and gaskets to ensure a solid connection. This housing is designed to work with the GT35 turbine wheel size and requires appropriate exhaust manifold and downpipe connections.
