TiAL Sport GT30 1.06 A/R Stainless Steel Turbine Housing

This TiAL Sport GT30 turbine housing features a 1.06 A/R ratio, which is a key measurement for controlling exhaust gas flow into the turbocharger's turbine wheel. A larger A/R like this one generally helps the turbo spool up a bit later but can support higher horsepower levels by allowing more exhaust flow at higher RPMs. It's constructed from stainless steel, a material chosen for its ability to withstand the high temperatures and corrosive exhaust gases found in forced induction systems.

The stainless steel construction means this housing is well-built to handle the demanding environment of a performance turbo setup. This specific housing is designed for the GT30 series of turbochargers, and the 1.06 A/R is a popular choice for builds looking for a balance between responsive spool and top-end power. Keep in mind that this part is not CARB approved and cannot be shipped to California.
