Fitting the audi 200 v8 torsen diff into our rear diff

[killerkali]

Have to pull my rear diff as it is leaking from the center of the case where it joins together. Already did axle seals and drain plug thinking it was either but no. I have a rear diff from the audi 200 v8, torsen style and have read of people fitting these into our cars. Anyone have any more usable info on this, I couldnt find concrete answers. I cant imagine the diff internals would just bolt into our case, but i could be wrong. Any help is appreciated !
Also, I understand this diff is weaker and may not stand up to street abuse, still want to try it out.

Is it 4:11 gear ratio?

It is, as a lot of the older Urs and s2 diffs were all 4.11

you need to swap your crownwheel to the v8 diff, turn down one side from 45mm to 41mm to accept stock bearing and use the v8 driveshaft flanges and bolt as they are longer.
