Sump wise house is correct with the CVH 1.8 sumps. Thats if you a can find one as just about everyone doing Zetec rwd convertions have been using these for years now so they are getting harder to find and more expensive.
You may still need to cut it back and big wing it but that doesn't take much.
You'll need a water rail to give you room at the back between the head and the bulk head, unless you don't want to keep your heater unit then you can just chop the bulk head back to make room. These are a little over £100 to buy but I have seen home made jobs that cost next to nothing and are quite simple to make.
Rather than using a dissy I would look at megajolt units if you going to use carbs or megasquirt if using injection.
Use a Ford type 9 gearbox as this is much simpler to fit that the MT75 gearbox unless you want a really strong gearbox then the MT75 is the one to go for.
Other than your mounts and wiring its all pretty streight forward (or should be
).
