What diff Fits E30?

[65Matt]

Do E36 diffs work? What all is involved?

There is also a 3.43 from an E28, i think.

correct, its actually a 3.46lsd. ive got that in my s52e30 w/ the zf trans. (80mph=4krpm in 5th.) i also have the 3.25lsd in the e30m50 w/ e36 getrag trans. i personally like the 3.25.....i must be getting old and soft. cheers,jason

Yeah... i have a 3.46 LSD sitting right next to me!...it has the factory rebuilt tag on it! Off an auto E30 from South Africa!

If u had a 4.10 LSD in good enough condition id swap you!

E24 diffs will work too, but like Jordan said you'll have to play with flanges and covers to get it in.

Z3 diffs ar a direct bolt in.

E32/34 diffs will not work.

What ratios can I get with a Z3 diff? I'm matching it to an S50 with the E36 M3 tranny, and I want something for a daily driver.

Why won't e32 diffs work? The e28 m5 has a the same large case diff as e32s have so it seems to me it would work since you can bolt large case diffs up to an e28, and you can bolt a e28 diff up to an e30. Maybe you could use the larger diff to offset the extra weight of an s50.

E32/E34 diffs use a different mounting that is not compatible with the E30.

The E28 M5 and E24 M6 have a different diff all together, not the same as the E32.
