From what I've gathered over the years about turbo's, is that they usually 'take out' and cost you some pistons or a complete engine, until you learn to tune it correctly and stop trying to find the limits.
that isnt the turbos fault. thats the tuner or owners fault. learning to tune a turbo? didnt know there was anything other than dont be stupid and blow your stuff up as a precaution.
when ya buy chinese knockoffs ya have to be prepared to pay the piper for being cheap. and that over boosting is a 50yr ago issue long gone today. all but a myth at this point.
