I know i read in one of the books rules to change to fully cybernetic if you nearly die. I can no longer find which book and what pages it is on. Can anyone point me in the correct dirrection?

You're probably thinking of the cybernetic reconstruction package on p87 of the Inquisitor's Handbook. It requires some XP and GM tinkering to work well, since you'll have to find a Magos willing to do such a thing. In my game, if your character is killed the GM allows the burning of a fate point to replace the fatally damaged area with a cybernetic (with quality dependent on what's available).

There is also the Rite of Setesh, Pg 140 Inquisitor's Handbook.
