I was gonna suggest that, drill a hole through the nut+stud or bolt or whatever when it' torqued down, then run a piece of wire that is fairly snug through the hole. Unless whatever force is causing your turbo to become loose in the first place is strong enough to break the wire, it won't move.

 

Yea. Good idea. Like a carter pin or something. You still have to be worried about the seal and you don't have an exhaust leak though through the whole process.
