What Transaxle Do I Have?

[MDAY69]

I'm hoping you guys can help me identify the transaxle I have. I don't have the car it came out of, only the transaxle (bought it on ebay for a project I'm working on). All I can tell you for certain is that it was sold to me as a "2000 Porsche Boxster 5 speed Manual". I've looked all over the transaxle and find a lot of "cast in" numbers which I assume are part numbers of the individual casings, etc. The only "stamped" number I can find is located on a machined area on the top side of the bellhousing. That number is EFD10020. What I'm trying to determine is if this transaxle has LSD or not so I'll know what oil to use. Any help is greatly appreciated.
