If I were to get one of these Kennedy conversation plates to link a Subaru engine to a VW transmission, I would most likely build an adapter in place of the throttle body so I could bolt a carb on it. I know that sounds sort of old school.

 

The thing I can figure out is the ignition. When did Subaru go away from distributors?

 

Say if I wanted to use a 2.2 liter. How could you control the ignition system without a computer since allot of cars today use a coil pack. Even if it did use a distributor how could you control the advance since once again the computer usually adjusts electronically.

A guy from Australia converted his EJ22 to a distributor-style ignition so that he could run propane instead of gasoline.

 

If it's ease of installation/servicing you're looking for, trust me when I say that the stock EJ22 fuel/ignition system is NOT hard to hook up.
