I'm assuming this is the auction you're looking at.

As good of a price as that seems, and the fact that the guy has 100% feedback, I'd still be weary of buying the kit. If you notice, the intercooler piping is not built to fit the sr20, it's a universal piping kit. The intercooler looks ok. I personally would not buy a turbo from a nonspecific seller. Nonspecific meaning he doesnt tell you who built the turbo. From personal experience, I would only buy a turbo from Garrett, Precision, Innovative etc. bc of the quality control and materials that go into their turbo's.
The wastegate and bov are also generic replica's, not saying that they dont work equally as well, just pointing out why the kit is so inexpensive.
