Well, aside that your sedan has a extra set of doors, the basic chassis is the same as the hatchback version.
A do have a link, but it is for a German forum (I don't know how your German is?) and a lot of the earlier pictures don't work anymore
(which is a shame because that was the really interesting part with a lot of the modifications they had to do to make everything fit)
There are some very knowledgable people on this forum. But not many people have do something this extensive.
So with all possible respect to everybody on this forum, I don't think you will get the detailed info you will seek during the conversion here.
I think you should look for someone who has done something like this before.
Some consider this to be the holy grail for AE92 modifications, and there are not a lot of people who have done it...
I know of 3 Corolla's that have undergone a similair build.
The German one, a guy in Russia has build a 4WD AE92 but not as clean as the German build and years ago someone in England did it, but I don't know much of the details of that build.
There might be more, but they didn't go public with it then
Here are some pictures of the Russian build:
This guy used a Corolla 4WD running gear and still uses the original 4A-FE engine.
