What constitutes a rebuild on a turbo ??

I have a pair of R34 turbos gathering dust, waiting to be installed.
I bought them off a chap who said they have no shaft play etc, which seemed true as when I got them I tried moving the shaft and there was no play. Is this the correct way of determining shaft play, as I was cleaning them up the other day to find that they both have about 1-2mm movement.

Your thoughts please

Should roller bearing turbos have any play at all???

I shouldn't think so.

Yep rollers have more play than plain bearings.......but 1-2mm is to much...

I've been told that because they've been sat for a while the oil that's in the bearings may have drained ? I'm not sure as I dont know the signs of failure.
could this be true ?

Put some oil in the oil feed and spin them over they do dry out.

cheers - can the lack of oil make them a bit "Wobbly" then ?

Not 2mm wobbly but it does improve play

If I wanted to replace my turbo's, but keeping with the twins; is it a difficult job ??
