Is super su and twrp rom specific or phone specific or not specific at all?
SuperSU is generic, same for all (most) devices, some specific devices or methods may require a specific version though. 

TWRP is very device specific, each build is customized for the intended device. http://twrp.me is the official site for TWRP which has a database searchable by device. 

CM13 is pre-rooted, you do not need SuperSU at all.
