I did look into using duratec into my mk6 escort but it was the problem of the inlet being on front which started my change of plan back to a zetec. Looking at the exhaust manifold for the duratec I was pretty sure it wouldn't clear the subframe and then getting a gearbox to match as well as the zetec has the starter on the back as upposed the duratec on the front matched with the cable clutch aswell
