Speed-density was the design in 1987 from the factory the best I can find. No mass air flow sensor is even listed in the parts guide for either the 4 or the 6 cylinder engine (you don’t tell us which).

So it didn’t need conversion (who would bother to do that anyway?) because it was already speed-density.

Why are you asking this about a 33 year old car? Building a mini-stock/compact class race car are we?
