I wouldnt be worried about turbo pieces going in your engine mate, most turbos fail at the exhaust side of the scope, I had a twin turbo engine previously and blew 6 turbos on it, never had any drams with engines, you see when one turbo fails the other turbo can not produce enough boost to even read 3 psi (read from gauge) , because pressure will always take the easiest option out, meaning that one turbo has failed and the other will just basically push air in to the other one because its closer (pressure follows path of least resistance) so i would imagine that as soon as the turbo fails there wouldnt be enough pressure to even push it through your FMIC etc . . correct me if im wrong just a thought!
