You have covered the 2 main areas of difference, by using your pulley mounted sensor, and the conversion plate for the EFI manifold. The charge carrier pipe will line up, its up to you what turbo you use a Fiesta one (T2) will spool up a lot lower down, where as an Escort item (T3) will give you a lot more power, but obviously with the lag.

As for wiring, either of the XR2i or EFI XR3i looms will do the job, IMHO if you want to do a mint job on it then i would fit an EFI XR3i loom, there is literally a couple of wire changes to make, nothing major, and it will look a whole neater and Genuine, fitting an XR2i loom will mean discarding part of your loom, joining the XR2i one into it, and then also doing some mods to the wiring behond the dash aswell.
