will this work for forced induction?

I was wondering if by using a MAP sensor from a SVO,Turbo Coupe, or other positive induction For product, I could get away with using my speed density system. I may be wrong, but I thought the turbo 4s were not mass air cars, especially the earlier ones. I got this idea out of a turbo book that said it would work for GMs, just thought it may work for fords. THANKS
