I don't know, I think if I were going to go through the trouble to do a turbo setup, I'd do it on a 302. Although it would be fun/funny to have a stout 4 banger. Imagine blowing the doors off some Mustang... In a Maverick... with a 4 cylinder.
I found a fairly complete turbo powered Pinto cruising wagon (77?) at a junkyard someone who knows there stuff should look into restoring I tried to post pic but forgot how.
