325i diff in a 320i?

[Cyril]

I got a lsd from a 325i for our 320i thinking it would be a direct swap but it won't fit.
What diff would fit a 320i? - does it have to be the smaller size?
Thanks
Cyril

325i diff will fit straight into a 320i. What's the problem (apart from being out dragged by Nissan Micras).

LOL - it's not too quick granted
Ok so it should fit, we'll give it another go then - the problem was the bolt holes don't seem to match up in the right places.
Thanks

bolt holes on diffs are usualy a pain to get lined up

persevere and she will go

Here's a guide to swapping diffs:

It'll be slower still, pulling a 325 diff ratio.

Yes, reckon it'll be slower off the line but not really bothered too much as it's just for a bit of fun, certainly won't be competing in anything!
Thanks for the info folks
