what are the 1.8 xr3i zetec engine out the escort?

105 and 130 bhp models, obviously 130 is the one you want

same for the 2.0 mondeo zetec?

dont know other than the extra capacity and the aternators at the back

which one is better?

doesnt matter both same power and same to fit, 2.0 just needs a few things swapping

how much power for each, quite easily?

as above

how much to buy a decent one?

proberbly around 100 - 150

how hard they to fit (mk4 escort)

the 105 will fit directly on your gearbox and just need to modify engine mount

the 130s require a cvh efi flywheel and clucth, the holes need srilling out bigger slightly to fit on zetec, need to have a modifed exhaust

also does anyone know what they are like on fuel?

as anything all depends on how you drive them, but they dont have any fuel adjustment on them its all ecu controlled and closed loop

ive got a 1.6 cvh fitted now with a few mods (4 branch and exhaust)
would there be much difference in power?

yes, the zetec will proved more took and by fitting it you will have already gained around 30bhp


does anyone know that the mpg are on the 1.6 cvh?

no
