In this process of learning more about turbos and the the turbo swap into a 240.I pickedup a 81zxt setup Exhaust man.
turbo,The compressor end "wheel" spins very freely but there is a little end play.Is this normal?If so is that space that oil takes up to make the "fluid bearing" Sorry if this a dumb question just woundering if this a unit i could use for my 72.Any info or sites that relate to turbo swap in 240 much appreciated!


Thanks Mark

Mark-
this is what it says right out of a factory 83 manual.

end play in axial direction- 0.013 - 0.091 mm or 0.0005 - 0.0036 in.
they show the measurement being taken at the hot section end with a dial indicator.
NOTE do not let the wheels turn while taking the measurement.
