What is an A/R ratio and why does it matter for a turbine housing?

The A/R ratio (Area/Radius) on a turbine housing describes the size of the exhaust gas passage relative to its radius. A lower A/R, like 1.02 in this case, generally helps the turbocharger spool up faster, improving low-end response. A higher A/R can help increase top-end power by allowing more exhaust flow.

What material is this turbine housing made from and what are its benefits?

This turbine housing is made from stainless steel. This material is chosen for its excellent resistance to corrosion and its ability to withstand the high temperatures and pressures generated by exhaust gases in a turbocharger system.

What does it mean that this part is not CARB approved?

CARB approval (California Air Resources Board) means a part meets specific emissions standards for use in California. If a part is not CARB approved, it cannot be legally installed on a vehicle registered in California, and it cannot be shipped to that state.

Product Details

TiAL Sport is well-known for making high-performance turbocharger components, and this EFR 80mm stainless steel turbine housing is a prime example of their work. This housing is designed to be a direct replacement for specific EFR turbochargers, allowing you to rebuild or upgrade your existing setup. It's built to handle the demands of serious performance applications, ensuring reliable operation under high heat and pressure.

Crafted from durable stainless steel, this turbine housing offers excellent resistance to corrosion and thermal stress. The 80mm A/R 1.02 specification is a key factor in determining how quickly your turbo spools up and where its power band sits. A lower A/R generally means quicker spool, while a higher A/R can help with top-end power. This particular housing is designed to work with EFR (Extended Flow Range) turbos, which are known for their advanced design and efficiency. When installing, ensure you use the correct gaskets and hardware to maintain a proper seal, as this is critical for turbocharger performance and longevity. Refer to the manufacturer's installation instructions for specific details.

This turbine housing is a critical component for anyone looking to fine-tune their turbo system's response and power delivery. Because it's a direct replacement part, installation should be straightforward for those familiar with turbocharger work. Please note that this part is not CARB approved and cannot be shipped to California.
