    OP is looking for a 3.73 lsd, diff price varies by lsd ratio and crustyness as Snap and Earl note.

    1990 325i racecar (ITS, former Spec E30); 2004 330i ZHP

      So I started looking on Craigslist and there's a guy in Chicago (kind of a drive but may worth it) that's parting out an e30 and he's selling a 3.91 lsd medium case diff for $250....thoughts?...only had one pick of it.84ee9c45988f52d2f8bff8a585d13bfe.jpg

        in Medium Case, the 3.91 ratio only came out of an E30 325ix which would be a VLSD/viscous coupling and has a [V] stamp on it. If it was an S3.91 clutch-type LSD from an E28 or something else then that would rock. It will have an stamp if its clutch type (sperrdiff) which is german for "lock diff" or something. Not to be confused with "sperdiff" which would be german for Sperm Diff.

        That pic does look like a small-case diff from a 318is though. I could be wrong though.

          He said it was a medium case so it's probably the vicious one then. That blows

            Have him take a picture of the cover to see what size case it is. Also see if he can take a picture of the tag on the diff.

                So, funny story. Started talking with a guy on Craigslist that was selling e30 parts and I told him I was looking for a lsd diff and he asked me about my car and we got to talking and I gave him the last 7 digits of my social security #, jk. The last 7 digits of my vin and I guess he was some fleet manager for car parts and he looked it up and I guess I have 4.10 lsd! It felt like a second Christmas when he said that. So sorry for waistin ur time guys, I guess I don't need a diff after all

                    better actually check. diffs can be swapped in a car's lifetime.

                      Why would u swap to an open diff?...and how can I double check?

                        1. post burnout vids

                        2. check to make sure the tag on the diff cover says S4,10 then post burnout vids for confirmation

                                That sucks. My compact came factory with an lsd but it was sold when the car was being parted
