88 with a S5 conversion??????

Yo-
i run an 88 its car, want to put the S5 engine in mine. i am pretty sure this is a common deal, seems pretty easy. Anyone have a good list of parts i would need convert my engine. I know so far I would need a ecu, rotors, intakes(upper and lower), harness, counterweight (is there a front and rear?). Thanks for the help.

Work it-

Thats funny I'm doing the same exact thing to my '88. it's just a bolt in conversion. You don't need to change the ECU as long as you use your '88 injectors. There is some vacuum line work that you will have to do. The front housing on a S5 is different (electronic oil injection) use your S4 housing. You will have to put your S4 throttle piece on the S5 intake so the oil regulator rod will go on. other wise the rest is self explanatory. Any other questions just ask
