tallest/longest diff that fits the E30?

[884door]

Your mileage will be worse around town with 2.79s. Why? Because you have to mash the pedal to go anywhere.

with the getrag 240 rpms will be stupid low...

[SLOWER]

I have a 2.93 and 80mph is @2600rpms

Thats what I'm talking about. What size tires you running? Engine and gas mileage?

I'm actually considering swapping my 4.10 out before taking a road trip to Texas...

So, any 84-85 eta then? (I know how to check the tags and such).

And I did the math real quick, 2.79 @ 80mph = ~2500rpm, 4.10 @ 80mph = ~3750 rpm.

Probably worth the afternoon spent swapping the diffs out for a 3,000 mile-ish trip.

No they don't. '84-8/85 production etas had 2.79's-- regardless of the transmission. Beginning in 9/85 (first month of '86 model year production) all eta's recieved 2.93 diffs, again regardless of the transmission, to cancel out the taller tires that they recieved compared to earlier cars. This information applies to State-side eta's. In Europe the diffs were optional and anything and everything could be installed.

thats what i meant i just crossed the 7 an 9's:zzz:

eta's with autotragic's run 2.97's

Im working on the most ultimate gasoline saving utilitarian e30 i can make, and so I want to throw the tallest diff in there I can. Ive heard numerous 5 series may have what I am looking for but I have little as far as specific info.

pretty much, its gonna be the slowest thing on earth. but thats what I need. im planning on doing suspension. itll still be fun in the twisties and save me some waffleswaffleswaffles at the same time.

s52-330i 6-speed-2.93diff. Lots of power.

S52???? are you suffering brain damage too? he has a 85 318 that he is tryin to save as much gas as possible, read the fuckin post

[Wh33lhop]

Seriously? Just get a civic hx.

[SpecM]

I'm pretty sure its the 2.79 from 84-86 etas
