Should R33 Standard Turbo Have Shaft Play?

[skiwhine]

hi been reading a few adds where people are selling turbos which state has normal minimal shaft play, now common sense 2 me says that it shouldnt have any as shaft play will just promote balance issues as it spools up,

however i have heard the argument that it should have a lil bit of play when off car as there is no oil in between the bearings, but i disagree as ive bolted a couple of cranks n cams in place n not that i checked but i dont remember any play in them....

so whats the verdict shoudl it have a little play or not? discuss....

every turbo will have shaft play, whether its brand new or 100k km old, its just depends how much play. The bearing type will affect the type of shaft play and generally you will find the non ball bearing type, "floating" bearings which are in the stock skyline turbos will have a bit of play. When there is no oil pressure there will be more play, and if you could check it with oil pressure you would find the play would pretty much go away, but thats impossible to check without losing a finger haha.

By play i mean only slight movement, almost barely noticeable, if you can move it a more than 1mm thats not good

Standard rotor shaft end play is 0.120 ~0.200 MM.
