What does the .80 A/R ratio mean for my turbo?

The .80 A/R (Area/Radius) ratio on this turbine housing influences how quickly your turbocharger spools up and where its peak power is made. A .80 A/R generally offers a good balance, providing decent responsiveness while still supporting strong top-end power.

Why is this housing water-cooled?

The water-cooled design helps dissipate heat from the internal wastegate actuator. This is important for maintaining consistent boost control and prolonging the life of the wastegate components under high-temperature conditions.

What material is this turbine housing made from?

This turbine housing is constructed from stainless steel. This material is chosen for its ability to withstand high exhaust gas temperatures and resist corrosion, ensuring durability and long-term performance.

Product Details

TiAL Sport is well-known for making robust turbocharger components that hold up to serious use. This GT30 turbine housing is a prime example, built from durable stainless steel for long-term performance. It features a .80 A/R (Area/Radius) ratio, which is a key measurement that helps determine how quickly the turbocharger spools up and where its power band sits. A smaller A/R generally means quicker spool, while a larger A/R tends to favor top-end power. This particular housing is designed for water-cooled internal wastegates (IWG), helping to manage heat effectively during operation.

The stainless steel construction means this housing is built to resist corrosion and withstand the high temperatures generated by exhaust gases. This is crucial for maintaining the integrity and performance of your turbo system over time. The .80 A/R is a popular choice for many setups, offering a good balance between responsiveness and peak power potential. It's designed to be a direct replacement for specific GT30-series turbochargers, making installation straightforward if you're rebuilding or upgrading your existing setup.

When installing this turbine housing, ensure you have the correct gaskets and hardware for a leak-free seal. Because this part is not CARB approved, it cannot be shipped to California. Always refer to your turbocharger manufacturer's specifications to confirm compatibility with your specific turbocharger model and application.
