v8 diff swap, parts.. and torque settings

[lind4hl]

found an torsen now and will swap them over soon, started to look on parts to order i understand that i need this:


1x N 905 144 01 flange gasket No more available! use tube sealant instead
1x B 016 409 399 B o-ring seal (right side driveshaft flange) right side 45x60x8
1x 017 525 400C o-ring seal (left side, bigger for v8 flange)
10x bolts that holds the crown wheel to the diff ( i dont know if these are nessesary, but i bought them anyhow, maybe some lock-paste on them, feels better with new anyways..)



also does anybody have some torque numbers on these parts??

[lind4hl]

no torque numbers are in that thread what i can see???

[lind4hl]

from the v8 i can find these o-ring seals:

B 014 409 400 AA
01E 409 400 40x52x9mm CBM/ CBN diff is this the one??

you do know that v8 rear diff, cant handle more than 450hp according to some people who tried it here on the forum, right?

[lind4hl]

yep, i will try it anyhow.. and no launch-control-banzai launches of course..

[lind4hl]

i ordered the parts today on V.A.G..

i will post up an how to and part numbers etc later..

but damn that o-ring seal from the v8 is expensive 50€

no-one have torque settings for these parts, i forgot to ask that..

I probably have the torques for ordinary rear diff - not V8 torsen specifically - but should be same... can you post a photo of exactly where you are talking about?

[lind4hl]

torque numbers where the crown wheel sits on the diff
torquw numbers on the bolt that goes thru the drive-shaft flange in to the diff
torque numbers on the scover on the right hand side.

i think that was all i need..

also the big o-ring (171x3,5) is not more available, and im not buying the tube sealant for 50€ from vag... so i will have to dig out an o.ring or some sealant on some other palce

If you have the sizes of the seals, just go to any bearing/seal place. Take an old one with you if you can, even of the incorrect size, it will help them find the correct type of seal for your application.

[lind4hl]

yeah i know, but since i want the parts when the diff comes i ordered it anyway, byt i will meausure it and put it up for other people

[lind4hl]

Paul: i would like to know the measurments on the backspacing (backslash?) on tje diff also, if you know what i mean..

[lind4hl]

did you find anything paul??

i should have done an write up today, but forgot the camera

Oem diff is out, only the crown-wheel to come loose.

I was going to open a new thread but I have thought that it would be better to ask it here as it has relationship.
I have also been searching the forum and haven't found the answer. I imagine it will not be possible to do, but I just want to make sure.
Is there any change to install the whole Audi V8 rear "bridge" (I do not know the technical word in english) in a Coupe? I mean, the V8 diff, subframe, driveshafts, hubs, discs, rear brakes, shock arms, etc. The thing would be to take all the rear part from the V8 and install it on a S2 Coupe.
Although I am sure that it will be wider, I just want to make sure if it is possible.
Thanks to everybody.
Cheers .
