To repeat: There are about 60 different versions of the T3/T4. It's just a standard classification for a whole family of turbos, not a particular model.

The Drag and RevHard kits both have some kind of T3/T4 turbo in them, which one in particular I don't remember off the top of my head. They also both come with an intercooler.

Don't worry about a boost controller until after you get the rest of the setup including your fuel delivery taken care of. The wastegate is perfectly capable of limiting boost.
