I had a '76 Volare wagon with a four speed and read up on them. I recall an article in Hot Rod in the '80s about adapting a turbo from one of the aluminum Olds-Pontiac-Buick aluminum 215s and the guy running it was winning his class with the turboed /6, which is supposed to have a stout bottom end. If you can find one of those old aluminum v8s with the turbo the match seems to be good with the turbo set up for a displacement a little smaller than the engine size so it will rev up fast. However, it may be easier to find a turbo from one of the Ford 2300 (122 cu in) engines, although that is not necessarily a good match for overall displacement. Mainly what I am saying is that if you adapt a turbo from another engine it would be a good idea to find one from an engine with a displacement a little smaller than the 225 size rather than larger. If the turbo is from a larger engine there will be a lot of "lag" and maybe you will never generate enough exhaust gas to rev the turbo.
