Here are the difficulties you will have:
S13: 89-93 - Wiring Harness, Heater Hose locations. If you're using the KA radiator, then you'll have to get a special hose.
S13: 89-90 - Power Steering Pump and lines have to be moved to Driver Strut Tower. Tachometer will not work. MAFS will work if needed.
S13: 91-93 - power steering pump is in the right place. Tachometer will work, MAFS will not work.
EDIT: Driver not Passenger, man I am slow sometimes.
