330i Rear Diff Swap with AT 3.64 diff questions (Updated video)

neoduffer · 04-07-2016, 12:59 AM

I just completed the swap. The change is very noticeable and I seem to run out of revs pretty quickly now. Overall it was a great way to liven up the car and make it way more responsive on throttle.

Did the same diff swap MT->AT (ie. 3.15->3.64 , in my case multiplied by factor of two, because of xDrive

) few months back. Now it runs simply WONDERFUL.

Yes, the mileage decreased proportinally, but.... who cares?

I also have a 330xi 6mt, was the fitment from the automatic bolt on ? im sure you had to change both front and rear diff, any other auto diff is bolt on ?

Yap, the swap was straight PnP.

Still have an auto diff from a 328 sitting in my garage if anyone is interested in it

Has anyone dyno'd the before and after Diff install?

Won't make much of a difference. At least, it shouldn't. This is a torque manipulator, not increaser.

did anyone ever consider a 6th gear rebuild after they installed a higher final drive ratio?
Since 6th gear is an overdrive anyway, this seems the way to keep the revs down during highway cruising. A big hassle though...

Already did a video, no speedo footage though. When it warms up I'd love to, we've got a good "Mexico" road just North of where I'm at

Sounds epic at WOT but that burble would drive me mental after 10 mins.

Did you mount the mic near the exhaust, and do a "voice over" for the footage?

I have a 2007 335i I'm trying to find out if it's compatible with the rear cv axle on a 2004 330 x.I

no.

different generation

even e90 330i and 335i have different cv axles.

Also my Diff Swap Impressions. Do it. Worth It.
