My journal bearing does the same thing. It may be spinning and it may not be. I have a .63 hot side and have no leaks anywhere.
I worried for 2 seconds before I took it to the tuner the first time. When we made normal power i realized it was just fine.

What does timing have to do with exhaust volume at idle?
really bro?.....
umm lets see: the more advanced the timing the less exhaust gas, the more retarded, the more exhaust gas.

everyone needs to stop comparing BB units to his JB unit, BB's will alomost ALWAYS spin at idle because of the bearing system, BB's aid in helping the shaft spin with less effort, but its the compressor and turbine wheel aerodynamics that account for the majority of a specific turbochargers ability to spool, take a "T" series JB Garrett and change nothing but the bearing system to a BB, you might see minimal gains at best, because the aerodynamics havent changed, you have just removed drag from the shaft.....

Greddy kits are JB units.

i like how none of those pics show the housing..... "clean engine bays!" ~ is that what you were hoping for in a response?

anyway, the greddy had a tiny housing, and the GT35 explains why it spun fine with an .82.

changes in timing also effect that like i was trying to get across to spectacle.

Not at all but all three spin at idle, that was my point.

Some people just say what they think and not what they know.

I'm not an expert, but the OP's turbo should spin at idle. If it isn't, something is causing it not to (Timing, Exhaust Leak, Poor lubrication, or Faulty Bearings)...

If he doesn't check everything over again, I'm sure we'll hear about his turbo woes' within a few weeks.

^anyway,

heres the deal: if he revs the engine, and then stops. the turbo should spin up, then slow down, and possibly come to a smooth stop if the housing is just to large for the compressor at idle.

nothing more, nothing less.

if it doesnt spin on the rev, or comes to a abrupt stop upon decel, something is up.

thats all.
