OBX Helical LSD

[matt]

the regular lsd works just fine

though i would love to learn how to service them

WR has one out of the case... haven't gotten around to messing with it yet. Probably this summer.

i'm ready and willing to experiment with this but I have a few hurdles,

1 - i have a 92 318ic and thus have the 4.27 open diff... i'm not sure they make one that works...

2 - if they do make something (or i somehow get my hands on a medium case 4.1 diff)... i would need someone with the proper tools to install it into the diff (i can install the actual diff itself into the car)

and then i can report back my findings... and trust me... i'll try and break it

OBX Is local to me. i have been to their shop a few times as my buddy buys wholesale from them. maybe i will hitch a ride with him next time and pick their brains about these units.

Do it. I asked a buddy of mine who is heavily into drag racing and said some guys do run them in fwd imports w/o trouble but couldn't get any more info... lame.

Hitch a ride to their warehouse and put one in your pocket. Report back.

Huh, I was looking at these tonight on the bay... Then I run across this thread.

Well if no one buys one anytime soon, I'd be up for the job, but that won't be for another 2 months or so.

You have to swap the whole differential. The inner part. The cases are the same.

[Mr Deagle]

ot, but can you put limited slip clutches in a non lsd case? like is there the provision for it?

[matt]

anybody have a reason why 325e's and 328i's supposedly have the same diff, yet it's different than e30 and e36 325i's.

I think I'm gonna guinee pig this but I want to make sure this company knows at least something about BMW fitment before I spend $400.

Huh? All 6 cylinder e30s and e36s (except euro M3) have the same diff *size* (different case, same LSD will fit, except e36 M3)

Why not just upgrade to a large case? Won't you be needing it with the turbo anyway?

yup....I was gonna get a 3.73lsd for $35 and it didn't work out lol

[CarsSuck]

hmmm...I wonder if its as strong

No. They may make another one that will though.

[matt]

so would that fit in a small diff case?

No. They may make another one that will though.
