Re: FP releases 3082, thats right.

A standard GT35R is a 3582. 61mm inducer 82mm exducer.

Garrett switched to naming compressor wheels after the bigger exducer size versus the inducer size, so all these 82, 86, 88, etc GT turbos are not that big. The inducer is the main factor in how much air the turbo can flow, since it all has to come through. Better wheel designs will make one turbo with the same same inducer as other be able to flow more air though. Generally a turbo with a bigger compressor exducer than another with the same size inducer as it will be more efficient at higher boost levels.
