3.63 Differential for E90/1/2/3 (not 335)

BIMMERPOST / Classifieds
Asking Price:
None

Item Interest
3.63 Differential - $600 Shipped



Open differential purchased new directly from BMW. Has 16K miles on it, like new (open diffs really dont wear out) Had input shaft modified to fit 325. Should fit E90/1/2 325/328/330 manual transmission cars. (your shop may have to swap input flanges with your stock diff) Gives the car some great pull in all gears, and makes 6th gear more useful.

I really need to get this thing out of the way.. its a great deal!

This is really a great deal guys. Of all the mods I have done, this one seems to have made the biggest difference in acceleration.

would this fit the 330i w/o any modification since you had to make modifications for the 325?

Yes, it would fit a 330 with no modification.

Again KS, thanks for the bump. Differential swaps are very popular on the E36 and E46, just something that hasnt caught on in the E90 (because there are so few used diffs available perhaps)

you guys want mods to make the e90 faster? This is one of the few things you can do to increase acceleration

BUMP.

How much of a pain of install is this (i.e. how much did it cost you)? This sounds like a very interesting mod for a manual tranny 325i or 330i.

Other than the faster acceleration advantage, are there any advantages with staying with an open diff as opposed to upgrading a 325i or 330i to a limited slip diff setup?

Sorry for the newb questions.

FWIW, this mod on my E46 made more of a difference than an intake, exhaust, pulleys combined.

They called this the poor man's supercharger on E46fanatics haha

Sounds like it...I'm very tempted...just want to know what the total price for a install would be...any ideas how long it would take?

Install should be about 3-4 hours labor (perhaps less) Whatever your local shops labor rate is will determine your total cost.

(sorry for the delay, went out-of-town and forgot my laptop charger)

I have also heard about great acceleration with the open differential, but it also eats more gas right?

I had it off my car for the last month of my lease, and, honestly, the gas mileage is about the same. These cars all have a 6th gear, so RPMs are still pretty low even on the highway. Of course, if this differential encourages you to drive more aggressively, your gas mileage would be affected

I'm open to offers...
