    E34 Differential Gear Ratios

    I have gotten my first e34 and have begun working on it. I have tried to do allot of research on these cars and it seems like there's allot of information about these, but there's so many different variations. I am looking at a parts car and i'm highly interested in the rear differential depending on the gear ratio. I know it's really easy to crawl under the car and scrap the tag to find out or put the vin in realoem, but is there a master list anywhere of what people have found in what cars?

    The car i'm looking at is a 95 525i with a 5 speed transmission

    If we could make a master list of what ratios people have found in what e34s it could possibly be helpful for someone researching?

    92 BMW 525I Touring Auto S4.10
    95 BMW 525i Manual 3.23


    if anyone wants to add what their car has, i'll add it to the list. Also if someone has any idea what ratio the 95 would have, i would greatly appreciate that as well.

    way too many
    Here's the link to Vine's former site with more diff ratios via the wayback machine. Their current website is broken.

    Numerous e31 and e32 diff's will swap directly with an e34. Need to verify whether medium or large case diff, apples to apples, medium-to-large, large-to-medium won't swap without a lot of extra mods.

    E32 yes, E31 sort of. See here, post 51 for E31 info.
