    So how much more power can this handle compared to the standard e21 LSD differential? Or is it just less expensive to acquire?

    This carrier unit can handle 300hp easily when it is upgraded to Stage 3 pack. Much more than oem e21 unit.

    Have you ever tried with e34 differential lsd?

    E34 has 188mm LSD unit, or 210mm. Those wont fit in small case E21 diff.

    You will need axles and the rear end of prop shaft.

    Was the e21 housing from an e21 open diff or was it an lsd originally

    You don't seem to use the original paper gasket on the housing. I used it last time and it leaked. Do you use only the sealant and tighten immediately to 50Nm?

    That's right. All BMW diffs after year 2000 use this system from the factory. Never leaked.
