I'm pretty sure the gt35r, gt3540r and 3582r are all the same thing and the 3574 is a non bb model with a slighty different comp wheel. Don't quote me on that tho.

Uncle henry has done his homework
Comp wheel is the same on all of them though. They all use a 3582 compressor wheel, the turbine is larger on the 3574. 74mm versus 68mm.
