you would need a 7A flywheel or the NG flywheel and machine the crankshaftpin for the ECU.. i think that would be it.. clutch fits on both..

I *think* it most probably will bolt on easily enough, how the ratios compare and how it will drive I'm not so sure.
Forum member Caterpillar from Norway will should be able to give you a comprehensive answer as he has a lot of knowledge on the subject. Try sending him a private message and direct him to this project thread.

You need clutch/fylwheel from 7a or 3b. That's all.
In my opinion NG Gearbox is too short. I use the 7a Gearbox from Audi 90. Because of the smaller tires from A90 to Audi Coupe its perfect.Audi Coupe Typ89 10V Turbo - VEMS - Billet K26 - Deka 630 - E85 - 3" Exhaust

I'm either to stupid or something is not right here.
Take connector "T2" for exampel, in the description it says that It's placed under the rear seat. And I don't have a single connector under there.
It's a similar story with the T8 and T5, I can't find a connector where the number of pins and the color is correct?
Could someone try to describe where I'm suppose to find these?
Just check out fat green/yell wire - it is pump feeding.
I could find out for sure when I'm in my garage, but you will likely find that quicker.
T5:
T8: it's probably some sort of coding plug under dash panel from the right: near Jetronic ECU and VEZ ignition ECU. What for do you need it? I could not find anything It affects.

I'll get back to this later, because I'm in kinda a hurry, but I found the signal wire from the ECU, and it doesn't line up with any wiring diagram I've seen so far.
Not a single connector or wire color seem to be correct except the pump main feed, which in fact is Green/Yellow.
But as stated, I'll share my knowledge when I get back home

Fuel!
So, what I ended up doing to straighten things out was to just measure my way through it with my multimeter.
I used a backup relay-box I had laying around and just checked where each pin on the fuelrelay came out on the other side until I found something odd. And at the last pin! I found a wire that didn't give power, and didn't ground, so I followed it and sure enough, it lead straight to the old ECU.
The ECU signal wire is GREEN with a VIOLET STRIPE and sits here;

So a couple of questions to you that seems to have some experience.
I basicly have 2 major problems with the MC-box...
1. It's off center even more in comparison to the NG-box. Which results in one driveshaft being too long, and the other side too short. Can I use the 7A-box with the stock NG driveshafts?
2. The gear linkage is working in the opposite direction. On the NG, there's just a shaft that goes in on the right side of the box, but on the MC there's a ball joint on top. Does the 7A hook up to the stock shifter linkage?
I'm gonna assume that number 2 isn't a problem, because the 7A was avalible in the Coupé. But I guess number 1 could differ, and if they do, I guess I just have to find some 7A driveshafts to go with?
