Yeah, but if you're running 10psi through them, they will last (assuming second hand turbo is in good condition). Note the OP has standard ECU and wants a $400-500 bolt on solution to a blown turbo. How he got the turbo to blow in the first place? Either debris or spinning them past their design.
If OP decides to go with a high-flow, might as well do the ECU and get it tuned. Ebay turbos are a hit and miss (judging from what I've read and seen). You have to wonder how much engineering has gone into a cheap ebay turbo.
The Hypergear sounds good doesn't it?
