S I have gone to stage 3 with a set of K04 turbos. My K03's are still good, not blown, not leaking and not cracked. I can provide pictures upon request, im just cleaning them up at the moment. I ran them with stock settings for their whole lives until 2 days before the Motor pull where i flashed NVR's stage 2 file and hit 20psi consistently without any issues. Thats the most abuse they have had.

Not really sure what to ask for them,  but they have to be good to somebody, just shoot me a reasonable offer.
