the serpentine accessories would go on... but then, why not spend naother $500 and get the intake, stock passenger header, downpipe, and intercooler, and maybe $150 for a stock turbo if you dont want to clock your hotair turbo ;p
all you need to do is get the accessory brackets, a/c compressor, alternator, p/s pump, p/s reservior, crank pulley..
im not sure about the water pump, it may just need new pulley, and you might need a different pump altogether.
you also need the belt tensioner.
as far as going for the gold and intercooling it, you need:
'87 intake - $150-200
'87 Turbo -$150-200
'87 intercooler -$100-150ish
Caspers Mat Sensor harness - $50 or so
'87 ECM $100ish
you CAN use a stock maf..hell you can use the stock ecm but it could have trouble accounting for the denser/cooler air charge.
intercooler brackets, and piping $100-150
passenger side header $75-100
stock down pipe $100ish
intake and valley pan kit $20
copper triangle gasket $3
