Probably easier to fix the 1991 than it is to fix up the 1989.They are the same generation cars and will have a lot of similarity, with the newer one having some upgrade differences.
Thanks for all the replys
No the 1991 is junk! The windshield is cracked and rusted out above so that it could not be replaced.
All the struts are junk, suspension worn out, transmission bad and many more issues.
I just replaced timing belt and water pump on 91 so the engine should have some life left in it.
As far as swapping the carb and manifold from the 89, I believe the injectors on 91 screw directly into the head don't they?
I am not interested in swapping the 89 head over, it might have issues and I am 60yo and would rather do more electrical instead of
If I swap the whole engine electrical harnness and the ECM from 91 to 89 will the firewall plugs be compatable?
What about fuel pumps? Are they in the tank? Is the FI pump in tank different?
Again thanks for helping me out guys.
