I have a bunch of parts lying around after I rebuilt the head on my B6. Below is a list of what I have. I will try to get pictures if you need them. I don't really know what the going rate of each one is at so throw out an offer and I'll work with you on what I think they are worth. If there is something you need like a connector or misc line, ask me because I might have it but didn't list it below.

RP Turbo K04 ~15-25K on it. No issues at all.
Racetec FMIC
Oil cooler lines from oil cooler to turbo
turbo coolant lines
radiator (no issues only changed to clean up engine bay)
radiator upper and lower hoses
ignition coils (r revision I believe)
APR red throttle body hose
Hood bra (carbon Fiber look a like) will fit over USP front and S4 w/ cupra lip
