What is the A/R ratio and why does it matter?

The A/R ratio (Area/Radius) on a turbine housing determines the flow rate of exhaust gases into the turbine wheel. A 0.82 A/R, like in this housing, offers a good compromise, allowing for relatively quick spool-up while still supporting higher horsepower levels.

What material is this turbine housing made from?

This turbine housing is made from high-silicon cast iron, often called 'Hi Sil'. This material is well-suited for the high temperatures and pressures of exhaust gases, providing good durability for forced induction applications.

What type of exhaust connection does this housing use?

This turbine housing uses a V-band clamp system for its exhaust outlet. This provides a strong, leak-resistant seal and makes installation and removal simpler compared to traditional flange and bolt setups.

Product Details

This kit includes the Garrett GT35R turbine housing, designed for T4 divided entry with a V-band outlet. It features a 0.82 A/R ratio and is constructed from high-silicon cast iron, often referred to as 'Hi Sil'. This housing is a key component for building or upgrading a turbocharger system, controlling exhaust gas flow into the turbine wheel to influence boost response and power characteristics.

The 0.82 A/R (Area/Radius) ratio is a moderate size, offering a good balance between quick spool-up for faster response and the ability to sustain higher power levels. The high-silicon cast iron material is chosen for its durability and ability to withstand the high temperatures and pressures found in exhaust systems. This housing is intended for use with Garrett GT35R turbochargers and requires a V-band clamp for exhaust connection.

Please note that this part is not CARB approved and cannot be shipped to California. Always consult your turbocharger manufacturer's specifications and a qualified professional when selecting and installing turbine housings to ensure proper fitment and performance for your specific application.
