What are the frontal areas of the Mazda MX-3 and the Toyota Supra?

I am doing a lot of research and number crunching for my '93 Mazda MX-3 GS Special Edition and want to do some mathematical comparisons with any turbo Toyota Supra that is early 90's or newer. I was able to find the aerodynamic drag coefficients without too much trouble, but, I'm having a hard time finding the frontal areas of them. Bically, I can drop in a fully built KL-ZE 2.5L V6 from Japan and tune/turbo it to 1000hp+ and, given the proper gearing, I want to find the maximum speed possible based of calm conditions and a flat surface. For that, I need the frontal area...
