Is shaft play normal on a new 35r?
So I just bought a new gt35r.
The shaft does not play in and out, but does wiggle side to side enough and hit the housings.
Any thoughts?

The wheels (both sides) easily hit the housings. They will wiggle back and forth hitting the sides.."tink tink tink". I'm not pushing hard, I just grab the wheel and push a little and it immediately hits the side. When I'm back in town, I'm going to swing by my shop and have them take a look.
Obviously, when the compressor wheel hits the side, the exhaust wheel hits the other side, since they are connected via the shaft.
The play on this new turbo is greater than I've seen on old stock turbo's I've pulled from MR2s. This is my concern...
When people talk about "shaft play" are they specifically referring to side-to-side play, in-and-out play, or both?
Thanks,
Ian

Usually, people don't specify which direction the play they're talking about is. But side to side play (enough to contact the housing) is bad. Something's wrong. A little in/out play on a new BB turbo is something I've seen before and "normal" for the most part. But side to side is no good.

I was told by the vendor that what I'm experiencing is normal on BB turbos that have not yet had oil run through them.. So I take it you guys totally disagree? Does anyone agree that side to side contact is acceptable on a new turbo?
Maybe I could post a video of the shaft play. I've never uploaded a video, what site should I use?

Well, I can't even do that until Friday when I'm back in town. I'll Youtube it friday night.
The shaft play feels loose enough that it would go further if the housings weren't in the way.

So now we have split opinions, Haha:
2 people (enzo, and vendor) are saying it just needs oil.
2 other members say it should not be hitting the housings (period).

They all have some play I would say around .5mm off centre isn't uncommon but I wouldn't want much more. Try spinning it with little force applied to the shaft laterally, with the turbo in proper orientation, if it seems to spin without hitting the housings, it should be fine.

It definitely hits the housings. I'm not pushing that hard and it is rubbing the housing. But if I spin it it seems to stay centered just fine.
I will remove the housings and see how far it moves laterally, without too much force.
