Interesting.

Raj, what e36 differential are you using?

I do suggest using the Redline Shockproof (Blue) gear oil.

Hmm wonder which carrier he used last that worked & i wonder why the other ones didn't.

To be honest i have no clue. I just posted up on BF.C that i wanted an lsd pack from an e36 and some guy just pm'd me.

From what i know(or what i think i know), all the LSD for e36s are the same. It's just the ring gear that's different. somebody correct me if i'm wrong.

Just a bit of thought.... this OBX E36 LSD looks a bit shorter, so it might be able to fit easier, but it cost like $500.

The custom aftermarket diffs I'm familiar with aren't machining the carrier. They are using custom main barrels for the limited slip housing that the ring gear bolts to. This yields a shorter assembly which will fit inside an unmodified carrier. There's a good reason for the price tag on these aftermarket units - you can't build a quality LSD for the e46 by mixing and matching off the shelf BMW parts.

Did you mess with this any further?

MikeyV89 · 10-06-2009, 10:29 AM

Sorry to jump in here and ask my question...but I have an e36 differential, everything from case to gears, its fully assembled. I know for sure it is a 4.44 lsd gear ratio. Is it possible to take all the internal parts and switch them into my e46 330i diff? I don't want to open my e46 rear diff then have to replace seas and whatnot.

Because its a nice e36 rear diff, and I need something to do with it

aggieE46 · 10-06-2009, 10:34 AM

That's what we're trying to figure out.

Although, a 4.44 might not be best suited for you.

MikeyV89 · 10-06-2009, 11:06 AM

I know its LOW, but why do you think that?

4.44 is going to be hella aggressive. You'll be shifiting a lot and lose a good amount of topend speed.

aggieE46 · 10-06-2009, 11:10 AM

You'll no longer have a use for 1st gear

Not yet, i was busy the past few weeks prepping for a track day. now that that is over i can go back to working on this project.

aggieE46 · 10-06-2009, 02:18 PM

Good deal

Keep us informed!

n2Bimmer · 10-06-2009, 04:05 PM

Good luck, in for the results

MikeyV89 · 10-07-2009, 02:40 PM

Well I can always switch it back, just I want to see what it feels like! HAHA, plus depending on how much top end I lose, it prolly will be better for the 1/4 mile because you still aren't (well I am not) reacing speeds over 110 mph. But I am still in question about if the gears will fit into the e46 housing...

There has to be some information somewhere...

it's been done and can be done. the hosuing just needs to be modified to have them fit.

But are you talking external housing or having to hone out and modify the inside?

and I was on the phone for 30 minutes with BMW, and finally I found out that it is a euro-spec part, its not even from this country its from an e36 3 series touring. It is a 4.44 LSD and I was shocked when I heard how much it was to buy reman'ed so I am tempted to sell it, but want to install it, just not sure what mods have to be done.

SL Blak Soldier · 10-19-2009, 12:45 PM

Okayyy so i've been busy/lazy to update. but sunday of last week i took a grinder to the housing.

With the ring gear...

Gives you an idea of how much i grinded down.

The LSD without the ring gear.

So my over all thoughts;

I think that the thickness of the walls around the output shafts are thick enough to handle how much i've grinded down. I don't think there is going to be any issue with the structural integrity as long as you grind it down just enough to fit he core in there.

I went through 3 metal cutting pads so i got a bit tired and just stopped there. I think if i cut it down a bit more i can get it to fit.

Also the pack looks a bit long, but i think if i could get it in there it can be shimmed to work correctly.

That's all i could think of now. So now you guys are just going to have to wait until i feel like working on it again i guess. LOL.
