hmmmmmmm, OPEN DIFF, whats that mean sorry, thats the OPPOSITE of a LIMITED SLIMP correct!

mrbobolina 06-02-2003 11:14 PM

Yes Open Diff means non LSD

SickFinga 07-03-2003 08:13 PM

m3 never came with open diffs

Soldo 07-03-2003 08:20 PM

so what then its a LTD SLIP?!?!
if so, PM me i'd be interested!

mrbobolina 07-03-2003 08:25 PM

Well I am not gonna argue beyond what I know. I have a 3.91 diff on now and that is LSD, it locks up hard core. SO maybe it is LSD, with a less lockup.

Soldo 07-03-2003 09:11 PM

alright people help me out here, is there such thing as a 3.15 BMW open diff. m3 or not?!

SickFinga 07-03-2003 09:30 PM

there is 3.15 LSD diff from 95 M3 also there is 3.15 non-LSD diff that came on standard 325i(s)
So if it came off his car it is non-LSD

Soldo 07-03-2003 10:11 PM

i see, so what, is the diff on my car 3.15 as well i have a 95 325i

SickFinga 07-03-2003 11:18 PM

if it's 5 spd - yes

98323IS 07-04-2003 06:47 PM

So I'm confused, is this LSD or no?? I just want both my tires to spin!!!!

mrbobolina 07-11-2003 07:34 PM

alrighty guys. The diff is 3.15. It is an open diff, it may have 5-10% lockup, but it does spin inependantly.

Sickfinga - sorry man you are wrong. And open diff did not come standard on the 325.

my 325 had a 3.15 LSD on it before I replaced it with a 3.91.

This diff is an open diff, from an e36 m3.

all e36 diff's are transferable. The M3 has bigger anxle flanges tothe diff, however they can be swapped out.

If anyone out there needs a diff, here it is for ya...

I hope this clarifies things for some people?

SickFinga 07-11-2003 08:46 PM

mrbobolina, ok lets rephrase that to LSD and non-LSD diffs.
1. E36 M3 never came with non-LSD diffs. E36 m3s came with 3.15 on 5spd and 3.23 on 5spd auto in 1995. In 1996-1999 they came with 3.23 on 5spd and 3.38 on 5spd auto. All those diffs are LSD.
2. E36 325 5 spd came with non-LSD 3.15 diffs as standard, e36 325/328 with AUTO gearbox came with 3.91 LSD diffs.

It is true all E36 diffs are transferable EXCEPT ti's.

mrbobolina 07-11-2003 09:07 PM

With that said... This diff is an open diff. it came off of an e36 m3. so it has the oversized m3 flanges for the axles. The gear ratio is 3.15.

SickFinga 07-11-2003 09:15 PM

How can it be from e36 m3 if it never came on m3????
Unless owner of e36 m3 changed his LSD on non-LSD diff.
