Diff problems

[stulane]

Hi Guys, need some help...

I took an e36 325i LSD and put it into the casing of an e30 diff. When i tried to drive, it behaved like a locked diff and didnt give any slip to the inside wheel, making inside the wheel spin when you went round a corner.
Took it apart but cant get the actual LSD workings apart so dont know whats wrong.

Other problem...

Wacked a random open diff on the car that i had kicking about just for temp. The plate on the back says its a 4.1:1 - as you would expect.

Problem is that the diff is only working as a 2:1 tested by spinning the prop and watching the wheel, prop has to spin 2 times wheel to spin once.
Top end is 100MPH max and 70MPH is @ 4000rpm on a 2.5 M50 engine.

Help, Any advice would be good!!

Thanks
