First you'd have to match all of the components to the kind of performance you want. My goal is a better truck engine than a stock 292, which is a good truck engine. For the first go around I won't use the turbo until I can see what the cam, higher compression , and TBI do. But yes I think with a basically stock 292 with some forged pistons a turbo and TBI would improve performance not sure about milage. Stuffing more air & fuel in it likely would not give better milage except you might not be working it very hard. Built for higher rpm who knows?
