Lately I have been looking at turbos and trying to get a better understanding of things because I have never fully understood everything about turbos.

Thing is im getting mixed up on what is what on wheel sizes. what do most people classify the turbo compressor wheels by, inducer or exducer? In the past I just looked at it like thats a what ever mm wheel. Looking at the garret stuff is what has me mixed up. For example, is a GT3582R a 82mm or 61mm turbo?
