Gm 6.5L diesel turbo specs?

I have a few friends who are diesel mechanics, so i have access to some pretty big turbos, and I'm looking for info on this turbo. Its called the GM4 and comes in 94-95 6.5 diesels. I cant seem to find flow numbers or a/r sizes or anything, but maybe im just dumb. Maybe someone can help me out.
