Fellas,
Received my 67mm bb turbo from a reputable company the other day. I'm a virgin in the turbo territory... so I was wondering if it is normal for a new turbo to have some play with the turbine wheel? I mean you can grab a hold of the wheel and it will jiggle a bit...hmmmmm:1poke:

if the play is really noticeable there is something wrong. turbos have very tight clearances and should have very little shaft play at all.

A little bit (very little) up and down is normal, in and out is bad (at least with a plain bearing turbo, not sure about ball bearing)

A small amount is normal on a journal bearing style cartridge. Once there is oil the turbo the bearings "float"
