Intercolled is best but not really important for you power level.
You will need the stock computer it is boost reference and will add fuel and retard timing as boost comes up. Works very well so no need to rebuild the wireing or use megasquirt its just too much to build for a car that does it from the factory with similair performance. Use the factory wiring harness as well. Then simply bolt it up and wire it up. Plug it in. Not easy but not reall difficult either the hard part the efi setup is done and turbo ready every thing else is plumbing and welding.
Be sure the fuel system will support the efi motor.
Keep the motor completely stock for 170 hp And plenty of tq. But very tame and easy to use and easy on the car. Also hook up the low octane fuel switch. Retards ten degrees so it will run on any swell you end up with in the tank. For the most part stock boost will run on. Good 87 and any super. Not like some turbo cars that are real fuel snobs these run on just about anything.
Not that you need it but the car will run much better and will be much easier to tune with an MS1 setup, which are dirt cheap. Not only will you be able to make more power but you can also do mods for better durability and mileage.
Also, something to consider even with an otherwise stock system is a turbo header and a free flowing exhaust, really makes any turbo engine come alive.
