dumb question.... 86 4cyl's

I was hoping they wouldnt be carbed............

I found a nice(atleast in the pictures) black 86 4cyl notch not too far from me. I wanted efi though. :/

How hard would it be to convert the car to efi? I have an entire efi car that I can use. Im assuming just punching a hole for the main harness, and a few wires under the dash??
 
My '86 coupe started life as a 4 banger (it was carbed.) It's a good idea to have a donor car for a v8 efi swap. Your best bet is finding a wrecked '86 5.0 for a donor, later year cars can be used but it's a little easier this way.
