I put a 1.8 zetec later silver top in my escort this is the easiest route to go you dont have to change the sump, pick up, and water pump also dont need to change the flywheel either. You even use the cvh engine mount, the best gear box to go for would be the s1 turbo box again bolt straight up. You need to use the zetec loom, i used one from a fiesta si. With the proper tools and parts this can be done over a weekend.
