Any babbit style bearing will need to have some amount of "endplay". I don't think it is likely a problem. Unless this is a ball bearing turbo. If there were no endplay, it would bind up when hot. Some babbit bearing applications call for as much (or more) as .100" which is nearly 1/8". I am sure they will be able to tell you if it's a problem, but if they tell you it is not, I would believe them.
The measurement to worry about is not end play, but deflection. And you will need a dial indicator to check that. I would be worried if it were more than .003" deflection. That's just off the top of my head, though. Keep in mind that the turbocharger shaft/turbines will be pushed to one side always when operating which will make the shaft endplay disappear completely for practical applications. So the endplay is kind of irrelevant.
