Later disco 1 autos are edc and need ecu ect to run, the change happened in 1996 power went from 111bhp to 120bhp, but doesnt feel like it!
You can fit std bosch ve inj pump in place of the ecu one so dont discount a late auto if you come across one.
whilst the above is correct, sort of, and I know I am splitting hairs, (sorry), but the EDC ( read pile of carp ) does not have any connection to the AT. I know you didn't say this,

just stating it for the avoidance of doubt!
The other problem with EDC is that parts, specifically ERR3337, number four injector with needle lift sensor are NLS = so, at the very least the EDC is scrap, potentially the vehicle itself is scrap as the MIL will be on, which is an MOT fail.
SO; an MOT failure EDC D1 ( which is an auto, it was not fitted to the MT ), could be a good buy for your conversion, providing its cheap, and also assuming you can source a standard pump ( and the injectors, (different pressures), though IIRC, these are only about £20 ish each, new ). It is a lot of work, but IMHO worth it. I don't do manuals either.
In terms of power, a full width intercooler, and the standard VE pump set up properly should give you around 145 hp, and this most definitely does feel like it. The economy you can achieve with careful driving ( I.E. drive like an old fart ) is impressive too. But, I am an old fart, so suits me sir
My own D1 auto had EDC, had as in past tense.. more noise than progress
if you ask me, and you didn't I know, but !!
