no point, they use the same kit in their turbos already

just get one... take it apart and it put it back together... Their problem isn't mainly the quality of the parts (some of them use air research center sections, etc scrap random parts) Its just the fact that they're probably assembled by some midget chinese children at a sweatshop for 19cents a week. I've ran one on my car and have friends who've ran them. Just take it apart.... make sure the snap rings are in right (tapered side should be facing outwards). and make sure the turbine seal still has spring to it.. put it back together, torque everything til its super tight (don't know the torque specs but i heard "if its not too tight, its not tight enough, if it broke, its too tight" )

Make sure you align the center wheel and turbine shaft right (the ebay ones somehow come balanced) Theres a site that took one apart and dissected it showing everything about it... The newer "ebay turbos" aren't soooo bad.
