what diffs fit a w201?
Ive found a guy selling a w201 3.07 ASD with driveshafts, but he says it has a bit of play in it. Easy fix? Im guessing its going to be expensive...
Yes thanks. I know its possible to swap the rear cover or something and it will bolt straight in, but I think I will still require w201 ASD drive shafts.

You can buy a new, complete LSD carrier that will accommodate taller gears than 3.07 from the stealer for around 1000 USD, last I checked. Not bad if you ask me. If you're going to fit it to a W201 that's not a 16v, you'll need a lot of other stuff to make it work.
Check this .pdf. It should answer many of your questions. http://www.w124performance.com/docs/mb/W...trofit.pdf

And theres no way im paying that sort of money for a diff on a car like this!
Thanks Ray! Its a bit late now, ive already bought it lol. Im not sure where the play is until I receive it. Ive found its possible to get a 2.65 ASD diff for a 124 and im looking around for one but they seem a bit thin on the ground. I'll keep looking but in the meantime this one will have to do.

You could add a Quaiffe torque sensing center to a 201 diff:

09-27-2013, 09:34 AM #10Going for high speed? The w126 300sdl had 2.88 and the 560sel had a 2.47 they are very common over here but I bet they had a much larger diff

(09-27-2013, 01:06 PM)hooblah Well not high speed as such, but id like a bit more of a spread between the gears, rather than silly quick acceleration. I'd also like to cruise at 90-100 without the high revs.
Highest ratio of any 201 diff was the 190D turbo, which was 2.65:1, but no limited slip. I believe you would also need to swap half shafts, as there's a difference in the flanges.

(10-04-2013, 06:03 AM)Eric78 The ASD is the easiest & probably cheapest way to go, it's 30% limited slip even if you don't use the hydraulics.
saw a post long time ago that built in an ASD diff in his w201,
he made a manual hydralic lock, like three pumps with hand = full lock,
and press of a button released the pressure, damn sweet setup.
the welded diff isnt that nice to drive, prefere the LSD, which is the only option i have driving w123s
how common is the w124 300tdt and the w201 250dt where you (starter of thread) lives?
they are high geared and with ASD. to get a quaife or custom made diff fitted in the housing must be a heck lot more expensive, and more work to.

10-04-2013, 01:18 PM #20hmm, found out that the w201 turbodiesels never was relaesed with right hand drive form, hence no UK...
but a w124 300tdt?
or w124 300td om606?

To summarise;
2.65 diff can be found in:
- 300D Turbo
- 300TD Turbo
- 250D Turbo Automatic
- 190D 2.5 Turbo
2.87 diff can be found in:
- 250TD Turbo Automatic
- 250D Turbo Manual = 3,46
- 250TD Turbo Manual = 3,67
ASD or not depends on how the car was orderd. Either diff can be had with or without ASD. The 2.65 is rare, especially with ASD. As far as I know the ring gear is different on ASD differentials, ASD can not be retrofitted to a non-ASD Differential, unless a gearset is available (I would not mix gears after they have done many miles).
W126 gears don't fit the W124/W201 diff housing, as far as I'm aware.
To fit the 2.65 from a W124 the rear lid of a 'big' (1.1l oil filling) W201 differential is required. Plus the ASD drive shafts are shorter.
The hydraulics are easy, but wiring is associated with ABS. A manual ASD switch to operate the valve is probably the easyest way to retrofit ASD. And keep in mind that ASD was never meant for constant use, but merely as a predecessor of ASR. Resp. to aid take-off in slippery conditions. The ASD unit is quite smal and weak, compared to "proper" LSDs.
Any many, many 2nd hand ASD diffs have worn out clutch discs and don't offer 100% lock anymore.

10-07-2013, 04:07 AM #22Yes, OM603 Turbo or 606 n/a in the W124 chassis. 300TD is a n/a wagon, I prefere to stick to the factory designation; resp. 300TD Turbo or 300D Turbo. To avoid confusions.
To summarise;
2.65 diff can be found in:
- 300D Turbo
- 300TD Turbo
- 250D Turbo Automatic
- 190D 2.5 Turbo

- 250TD Turbo Automatic
