what are the 1.8 xr3i zetec engine out the escort?

same for the 2.0 mondeo zetec?

which one is better?

how much power for each, quite easily?

how much to buy a decent one?

how hard they to fit (mk4 escort)

also does anyone know what they are like on fuel?

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

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

would be great if someone could spare a few mins..

cheers
