It also doesn't have the built in pump, so if you want to run a trans cooler you will need an external pump too.
I have a JDM Legacy Spec B 6 speed and it does have the internal pump. I think it goes by the year, 2007 and earlier 6 speeds usually have the internal pump and the newer units do not have them.

I track my 818R with 250hp and no LSD with no issues. A lot depends on your suspension setup and the types of tracks you drive. Autocross and slow tight turns are where the LSD really shines.
