Default GT28RS: What amounts of PSi can it push, how do you control the internal wastegate?

I really hate even ask this, but I have been looking alot. I have a 95 coupe with an LS swap with a Turbonetics T3/T4 currently. I would really like to get the disco potato, just due to the great streetability it seems to bring.

Any links or help from gurus will be greatly appreciated.

If you're running a t3/t4, i'd opt for the atpturbo.com gt28rs "t3/t4" drop-in option. That is unless you plan to swap manifolds & downpipes. You could block of your external gate and run the internal. An internal gate is no more complicated than an external being that it needs a vaccuum source to open up. You'd need to ask which size spring your internal gate is though.

the only worry i have with an internal wg on the gt28rs is, you cannot clock the turbo without affect the internal wg positioning.
