I've heard of people using the CT26 as a good upgrade, from what i've heard its a bolt on apart from a couple of oil lines. The twin entry model off the mr2's need a new manifold made, but the single entrys are the bolt on. I'm just going on what i've heard but, you know my 3TGTE is sitting on the garage floor atm 
This is probably the cheapest upgrade i can think of, then you start going into custom manifolds and big ni$$an motherf***ers  .
EDIT: should really read what your asking before i reply hey. The 3TGTE computer should be able to handle more boost (<15psi), but then you run the risk of leaning out with the injectors. by upgrading the injectors you will have the same duty cycle but more flow, hence a much richer mixture over all RPM range, like i think simon mezz found out with his 400+cc/min injectors (the oxy sensor is too refined to selftune). Once you've upgraded turbo-->injectors-->computer your stock pistons may not be able to handle it. the cheap option would be to go with a high-flow CT20 or CT26, leave injectors, intercool, tune and not worry about custom manifolds or aftermarket injection. The powerful option would be something like 2L gemini hepatite pistons or forgies, aftermarket computer, W58 box, hilux diff, upgrade fuel lines, surge tank and garret turbos.
