I think the diffs have different ratios, i.e. 3.0 engines have 4.1 diffs, while 4.4 engines had 3.64 diffs or some similar ratio.
I'd delete ews all together on a swap like this.
The 8 speed transmission has already been done, and there's information and kits available online, so that part doesn't scare me too much

I'm thinking about that as well, upgrade tranny to ZF 8HP and then get SC kit for M54.
Haven't decided which route to go. If there's a simple way to upgrade to M62/N62, that'd be cheaper.
I can find a used running X5 4.4 or 4.6 for 2K canadian, and swap out all the needed components.
I can grab engine/tranny, front subframe, front diff, rear diff, both driveshafts etc. I just want to know the specifics based on someone who's done it before.
SC kits start at 5K USD, which after all said and done will come out to 10K CAD lol!
I was also thinking of M57 option, but don't see it for sale anywhere in Canada.
