What does the A/R ratio mean on a turbine housing?

The A/R ratio, in this case 0.50, refers to the area of the turbine housing divided by the radius. A smaller A/R like 0.50 generally leads to quicker turbocharger spool-up, meaning the engine reaches full boost sooner.

What is the benefit of an integrated wastegate assembly?

An integrated wastegate assembly combines the wastegate function directly with the turbine housing. This simplifies the plumbing and installation process compared to external wastegates, and ensures precise control over boost pressure.

Can this part be shipped to California?

No, this part is not CARB approved and cannot be shipped to California due to emissions regulations.
