Audi 80 KE-Jetronic fuel system
 

Audi 80 1989 with a 1800cc 4 cylinder engine and a Bosch KE-Jetronic fuel system. The problem is getting spare parts for this fuel system is difficult in my region so, my question is how to change this mechanical fuel system into an electronic one. I was thinking of getting an electronic fuel system from an engine (may be a model or two after mine) with the same dimensions and installing it.
what do you suggest can be done ?
