Question regarding lsd compatibility

[MeCarTay]

My friend is parting his 79 733i (eurospec) and I'm wondering if the lsd would be compatible with my e30. I'm guessing it is, but would like to confirm it before I make him pull it off for me. Also if anyone knows the ratio that would be sweet too.

probably not.

[ethirtydavid]

verdier, you gotta actually make your e30 look like your sig.. hah

[MeCarTay]

Anyone else know for sure?

No. A 7 series (E23) uses a large case diff and that one is way before the suspension change. What you want is either a small case diff out of an E30 or a medium case diff out of a 5'er E28 ('82 - '88 ) or or 6'er E24 ('83 - '89 ) . Sorry.

Most e30's ran medium case diffs. Only the 316s, 318s and 320s ran small case diffs.

And those only in the early models, right?

yup

It will work if I remember correctly, just gotta have hte half shafts and case from the E30 to bolt it up right..
I've got an E28 diff in mine right now.

technically, no, i have a 91 318i with an m42 which had a small case. any 4cyl e30 that wasnt optioned to have limited slip had a small case.
