i just picked up a 97 impreza for $600 it is still pure stock and i have read up on running e85 infact dabbled with it in my 06 wrx. what i am looking for is a start for an ej22 build to run e85. would the 22 be a worthy build or should i be looking for a 20 or 25 swap. or even go outragous with a eg33 swap. just asking for opinions on it i know it doesn't fit here really but i really want to go e85 so asking people already doing it is a good place to start.
