Yes those cheap ebay turbos are garbage. I saw one first hand last November. A customer came to me after being his NAD'S kit from me and had issues tuning it. I told him to bring it around and I'll do it for him. (His intercooler was like a strainer, lol). Anyhow I saw the new turbo and for some reason I put my hand on the outlet pipe of the turbo to give the hose a good move to see if it was on tight. The inlet half of the turbo was moving against the outlet half. Like the to halves weren't held together. It was quite bizarre.
