As far as I am aware, Subaru has two general lines of CVT's.
There's the "regular" ones (used on non-turbo boxer-4 engines), then there's the "high-torque" ones used on turbocharged boxer-4 and naturally-aspirated boxer-6 engines.
I would believe that the architecture of the non-turbo boxer-4 engines between both models may share a lot of the same major things like the case, but may not share the same exact components due to differences in engine output. For example, the Outback CVT may have heavier and/or more-durable components than the one on the XV/Crosstrek as the XV/Crosstrek engine has less power output, assuming comparison done on USA market vehicles.
