Turbo drama
For the record, I searched.
I just bought a new Godspeed T3 turbo, put it on, primed it, and started it. Drove for about 50 miles while not boosting. Then I boost once to 3 psi, and all of a sudden no boost. Drive back home and discover it has shaft play on the compressor side. Radial and axial. Never took it off to check the turbine side. Enough to barely scrape the housing and would obviously cause the no boost problem. What happened? I never touched the unit at all. Just put it in. Manufacturer defect?

Is the turbo water cooled and are you utilizing it? How was the shaft play before? Check your wastegate to see if they're holes in the boost signal or your wastegate is loose or disconnected.

Does it sound absolutely horrible even when not in boost (grinding sound)? My ball bearing OBX turbo totally died after about 5 minutes of driving but the shaft actually bent a bit. If the turbo is still quiet and you can see it spinning freely then it could just be something as simple as a coupling that has blown off.

Damn, this sucks. A leaky hose to your WG would cause more boost not less. I am calling defect, since the wheel is touching the housing. Or you screwed up hooking your oil supply up. That would be the first thing I asked as a seller. It would take a special kind of idiot to screw a turbo up enough on installation to cause this.

other then warranty purposes, why else do you really need to prime the turbo with oil?
If I am correct, the turbo doesnt see any sort of real load at all at idle? Just something like a slow rotational speed of like a ceiling fan or so? No real load or stress, I wouldnt think enough to cause it to damage before the car builds oil pressure...which takes how many seconds from firing to running?

You still might not have had oil in the feed line. I'd recommend in the future pulling your ignition cable, removing the oil feed line, and putting the oil feed line into a clear plastic bottle. Crank until oil comes out at a steady rate. Took a really long time for oil to finally prime through my -4an line.
