If ya want to know if your E series box is lsd.
# AW11 - use an E51, with the linkages facing forwards
# AE92/92 - use an E58 and E52. Quite rare to get an LSD though, if you do, it will 90% likely be a MAP sensor version.
# AE101 - use E58, and LSDs are far more common.
# E58-474 -> open centre
# E58-11C -> LSD
# E58-XX* -> where XX are two numbers, if * is odd, you have LSD.
# E58 LSD and NON-LSD CV shafts are non-interchangeable.
# E51 LSD and NON-LSD CV shafts ARE interchangable.

If you put an E series on a N/A engine you will have veru good fuel economy but it will take you 30 seconds to hit 100kph. as MYSTIK said.
