I'm guessing here guys but I thought the DURATEC engines were from the US & ZETEC from Europe.
I know the DURATEC designation was given to V6 engines used in the Cougar, Taurus & Mondeo. In the Probe, TX5, Telstar the V6's were Mazda K series were used & replaced with DURATEC's. Its also a DURATEC V6 engine in the Mazda MPV & Kia people mover, as I understand. Don't recall ever having seen DURATEC used on a 4.
I also understand that Mazda have been charged with developing new 4 cylinder engines for the Ford group, including PAG.
This may expalin some of the confusion/lack of answers.
