I don't think doing a port injection wouldn't be that big of a deal anyways. All you'd need to do is put injector bungs on the manifold which shouln't be too hard...
one of the things that intrigues me the most aboutr efi, is that you could potentially have a switch to change from power mode, to economy mode, to emmisions mode.. and drive around with whatever setting is convienient at the moment...
imagine being able to dirve around with low fuel consumption but instantly turning up the fuel for power..
kind of interesting don't you guys think?
