hi im swapping my 1.6 zetec from my escort to either a 1.8 OR 2 litre

Ive got the chance to buy an ''escort ready'' 2 litre ie with the sump,pickup pipe and water pump off escort OR a 1.8 zetec.

Not sure which to go for, will the 1.8 be easier to install? despite all the right changes made to mondeo engine im wondering if it will be any more difficult?

Im keeping my flywheel, clutch and gear box off the 1.6

Any opinions much appreciated

cheers
