GT series turbos are made by Garret, Turbonectics does not use the GT series design.
I deal with the 35R's on a daily basis, as well as the 30, 37, and 42.
Unless you are going to use the full potential of the turbo, you can always step down a size.
930gt-40r, what type of power are you looking to put down, and I'm guessing that you want to spool around 3krpm? also what boost level will you be running?
