The Focus exhaust manifold is very different from the contour manifold. They do have the same bolt pattern so technically, you could use one, but I wouldn't. My dad has a Focus and I've seen both our gaskets and the Cougar/Contour gasket is 3 times thicker than his. It just looks more solid.

Also while you could bolt a turbo to a Focus manifold, I'd be tough because the Focus doesn't have a front engine mount near the radiator so getting the turbo inlet pipes to clear it would be tough. If you could get the Focus manifold to work, then I'd use that gasket. Otherwise stick with the gasket for your car.
