Is there anyone that can tell me what are the main differences between the zetec and duratec engines (2.0L)?

I have noticed that Ford use the Duratec engine when wanting an engine for higher performance cars (Eg. ST170, RS, etc). Why is this- Is it a better base to work from to get more power?

In fact why do both the zetec and duratec engines exist? I know Mazda now look after 4 cylinder engine development (MZR series) but wouldnt ford have been better of in the past just developing the one engine?

Im probably wrong, but what Ive noticed so far is that the duratec seems to be mazda sourced or mazda developed engines, zetec seems to be ford europes own.

Thats just a guess- Im curious too - Bump!

It also perceive the Duratec to be a better engine. I think i would rather the SR2 2.0L engine than the Focus 2.0l Zetec engine

Actually Im pretty sure im right - I keep on reading articles on different duratec cars with "engines sourced from mazda", likewise mazdas with "improved duratec engines".

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.

zetec is a iron block i4. the Duratec is a alloy i4, share little in the way of parts. Duratec is from cosworth and mazda?

about the confusion, it extends to ford itself... about the rally car
"The engines have to be based on a production unit within the Ford range, and the Zetec engine is the one chosen for the Focus rally car. Cosworth admits that nothing else on their rally engines are standard production car items! Curiously, although the engine really is based on the Zetec (unlike the predecessor of the current CR-3 Formula One engine which simply used the Zetec name) Ford insist the rally engine is in fact called the Duratec engine, not Zetec!"
