If you're talking about a genuine NOS ceramic-impeller-equipped GNX turbocharger assembly, it certainly would be quite valuable. However, a good chunk of that value would depend on the serial number stamped on the rectangular Garrett plaque on the compressor side; this will prove authenticity and either tie it to a particular car or confirm that it was an uninstalled unit (and not stolen, or parted from a stolen X). If big bucks are being considered, then deduct $2,000 from the prices being postulated if that Garrett plaque is defaced or missing-- e.g. $5k becomes $3k. Don't laugh-- have seen this happen. Crazy, but that's the reality.
