they won't fit by any means mate.. there are loads of differrences, made all the more confusing by Ford badging some zetecs as duratec.
easy way to tell... duratecs are chain driven cams and the exaust exits on the same side as a cossie/pinto
zetecs are belt driven cams and the exhaust exits on the same side as a x-flow/bda

Proper Duratecs are great engines, some nicely tuned examples are found in the kitcar world, and yeah the Mazda MPS cars have the 2.3 Duratec with Turbos strapped on. My ST has a proper Duratec engine as well. (please no one try to contest that)
Duratecs have chain driven cams and compared to the Zetec, the exahaust and inlet manifolds have swapped sides (i.e the exhaust is round the back of my engine, compared to a zetec where it would be round the front)

depends on what you're after imo.. there are plenty of bits easily available in this country for building a zetec turbo and one could probably be done relatively cheaply.
I think turbocharging the duratec would probably cost a fair bit more due to one off bits and development, but I seem to remember people in the U.S. were already turboing these some time ago with very good results. speak to some engine builders you trust re this option imo.
as far as turbocharging a zetec goes, I'd say start with the ST170 engine and go from there. it has a much better head than the other zetecs
