Fitting a 1600 Zetec-E is a waste of money. The bigger ones (1.8 and 2.0) in the Mondeo MK1/2 should be fitted with a MTX gearbox, they must be converted to make the BC box fit. And Moneos camw with different oil sumps that won't fit a Fiesta or Escort. Go for a Zetec 1.8 out of an Escort or Fiesta (as mentionend above) or better: keep the CVH. A 1,6 MFI N/A is one of the most reliable engines made for the Escort.
