Former Moderator. RIP Icemark.
Well the 89 motor will bolt in just fine, BUT electrically they are nothing alike.
So that means either you change the front cover, MOP and use all the S4 intake parts and the S4 engine harness and ECU, or you do a custom harness and re-pin electrical plugs to make the S5 harness and ECU work in the S4 car.
Simple swap mechanically, pain in the *** swap electrically.
And there are countless changes between the two years you mention.
