ipd has the cam. It is good enough for your motor and power level. they also have gears.

Exhaust is custom local, or talk with thelostartof on turbobricks. he sells custom 3" turbo back exhaust for a decent price...

There are also the OBX cat back system (amazon, ebay). not a bad deal. It's only cat back and 2.5 inch.

I prefer the 3" turbo back as it really helps the turbo.

You don't want to do too much to that car. 89 is still a skinny rod year I believe. so no more than 1 bar of boost. the turbo plus should be plenty.
