The 08+ Sti is using the 11 mm pump because it has one more AVCS than you and needs to keep hydraulic pressure for that.

The twin turbo legacy is using the 12 mm pump because it has to support the sleeve bearings of two turbos. I would not at all jump to the conclusion that the twin turbo legacy holds the same amount of oil in the sump as you.
The gc8 engines that used oil jets for cooling did not come with anything more than a 10mm pump.
