Diff ratio

Recommended Posts

Does anyone know the diff ratio on a E30 325i auto?

Were there several different ones? Most common? And did it change on an LSD?

Cheers.

3.73 for both auto & manual from what i've seen. Not seen many 325i's but from memory they have been the same

I have a M325i, it’s 3.64. 3.73 is close though, thanks.

Is it easy to have the ratios swapped? Sorry for the uninformed question.

M version may well have come with 3.64. Have had a couple in the workshop in the last couple of months but not looked at the ratios on them.

What are you wanting to achieve?

Looking at picking up a second hand diff from a 325i auto, wasn’t sure what ratio was likely to be in it. And it should be LSD.

Typically the Euro 325i is not LSD, unlike M. Most SA 325's had LSD

I’ll update it when I know or have it in my hands.
