I drive a 2003 si. The motor was swapped with a k24a4 with intent to do an all motor build. I recently found a guy selling a used cyber nation kit for 2000 bucks. My question is should I even go that route without swapping internals? And if it will reliably run without doing so what should I beware of when buying a used turbo? Keep in mind the guy live far away from me so I can't see the kit in person.
