FYI, there's no more than the normal amount of shaft play.

Yeah... That's not right... Sounds like the compressor wheel is all over the inlet. Any marks?

Sounds like a rebuild in your immediate future.

Have anything to do with this ad?https://www.miataturbo.net/forum/t31387/ It got jealous becuase it heard you were trying to step out on it so it threw a fit.

Have you checked the backside of the turbo to see what it looks like?

A bearing doesn't really have to have play to be worn out, or damaged. Sounds like rebuild time, or a new turbo.

Supposedly this shop in Miami rebuilds them, but for $250-300 I'm not sure it's even worth it.

I dunno, I figured they could be. Seems like Ive seen them rebuilt. Surely the BB assembly is removable from the CHRA somehow... isnt it just a cartridge pressed in or something? Cant say Ive seen a BB turbo apart, plenty of sleeves though.
