It has a little bit of shaft play, maybe 1mm side to side and a little less axial play.

Doesn't seem all that bad but I am not too familiar with the allowable limit. I have not taken it apart to see the bearing.

Odd boost noise following turbo install - cburke996 2017-06-20 10:25:59 (562 views)

  - almost sounds like air whistling past your diverter valve. - a4kquattro 2017-06-25 11:25:00 (332 views)
    - The new turbo has a build in recirc valve, don't have the old DV in anymore. - cburke996 2017-06-26 09:14:31 (330 views)
  - Thanks for the vid. If we have a situation where two completely different turbos are - rallyfreak202 2017-06-22 10:07:52 (406 views)
    - Could a tear in the wastegate diaphram cause a noise like this? - cburke996 2017-06-22 10:40:16 (312 views)
      - I would think if it is only during low boost that it isn't a boost leak but - drppedfikse 2017-06-22 12:11:03 (367 views)
    - Good point. Sounds like a boost leak test is in order. And probably a smoke test for vac leaks. - cburke996 2017-06-22 10:39:39 (358 views)
    - Yes. That is what I noticed on the video I posted as well. Either something is loose - drppedfikse 2017-06-22 10:29:59 (373 views)
- Is it similar to this? - drppedfikse 2017-06-20 12:27:49 (457 views)

    - What is the SN on the blue and silver plate on the turbo? Or post a photo? - UrS4boy 2017-06-20 12:14:17 (471 views)

        Post video and we can help troubleshoot. How does has the noise changed since turbo swap?   -  rallyfreak202  2017-06-21 09:26:27 (383 views)
        
        Do you know the history of your turbo? I expected 2004 GB RS2 clone but that looks like real RS2   -  UrS4boy  2017-06-20 13:04:26 (543 views)
        
        It was part of that group buy several years ago.  -  cburke996  2017-06-20 15:37:39 (374 views)
        
        Hmm... strange numbering for a GB turbo. Almost OE (which Borg Warner was trying to hide)   -  UrS4boy  2017-06-20 15:44:37 (366 views)
        
        Dave, mine was part of the '04GB and the tag looks like the pic you posted.   -  mtg  2017-06-20 19:11:39 (389 views)
        
        Thanks for the confirmation Marc. The GB turbos did not say "7200" anywhere (IIRC)   -  UrS4boy  2017-06-20 19:19:53 (371 views)
        
        Well I can certainly be mistaken...it could just be off a real RS2 then?   -  cburke996  2017-06-21 09:35:53 (356 views)
- Ball bearing turbos sound quite different than journal bearing turbos. Could be completely normal. - ThetaTau87 2017-06-20 10:58:01 (447 views)
- Wastegate is shut already. 2.2l can't spool turbo without load. Get a 2 step tune ;) - ringbearer 2017-06-20 10:29:33 (363 views)
