E-bay is filled with replicas that are not just cheap copies, they are totaly unusable! This turbo run for 2 minutes before glued compressor housing flew away. I don't believe anybody actually wants to purchase a turbocharger that is not working.
I've seen bad and less bad copies from china. As long as it has a Chinese trademark and is actually usable, it's up to customer to decide if it's worth the gamble.
But these are totally worthless artifacts made to look like "the real thing".
Only thing that saves them is hoards of big-eyed kids who buy these things and then keep them on the shelve dreaming about the car The Fast And The Furious. The moment someone finds out the way to actually bolt this paper weight on the car is the moment $hit hits the fan.
Thank you for your time,
