No your 89 4 banger was not carbed from factory........ And I assumed the OP just wanted to swap the long block parts not the tbi too.
Blocks are the same. Oil pan will have to be swapped and maybe the pump pickup. I have examined nearly every year model 2.5 and there just in no differences in the long blocks for installing purposes. Some gaskets and bearings are different between years.
