I think you need to decide if you want clutch type or helical type,
one uses gears to transferr power (heilical)
the other uses clutches(clutch type)
I'm getting a KAAZ LSD put in my celica end of this month, it has 6 clutch plates opposed to the TRD USA 4 clutches, it also has about 15% bigger friction surface on the plates than the TRD USA, i dunno the spec on the JDM LSD, but its probably one in the same, I think other companys make the clutch type LSD.
