Engine Question

[JimFestiva]

All of my Festivas are 1990 or newer. I just purchased a 1989 FI Festiva engine and noticed it has a vacuum advance on the distributor. Are there any other differences between the 89 and 90 engines? Also, can I convert it over to being the same as my other Festivas? If so, what do I need to do?

think you just use your efi intake but I'm sure someone will buzz in that knows if their is something else you have to swap
