4.1 lsd slowed 325e down
just put a 4. lsd in a 325e and a major speed difference, slowed me down alot, 5th at 4000rpm id say maye only like 80 or 90 mph
can i take the guts from the 4.1 and turn the stock differential from the 325e into a lsd?
or is there another way to get my rpms back, maybe a e30 m3 tranny, will that work?

A 4.10 is WAY too short for a mostly stock 325e. A 3.46 is about the max that you want. Sell that diff and get something else...

It may have felt faster, but you really lost a lot of the powerband.

When the speedo is showing 190+Km/h, and we consider its not 100% accurate, so lets say it was 180...thats still VERY good for a car with over 400000 original Km, and a 3:91 repalcing the stock 2:73....

I'm pretty sure i got a stock diff in the back but mine has posi already. Creating an LSD is just a matter of welding the the trow out gears together. But then it's constant. is a new diff a huge gain, i'm pretty impressed with the stock one. I have done alot of work to the motor and it plays the powerband nicely.

A chip will bring an ETA up to 200lb/t, those engines are highly underated.
