I have ball bearing turbos right? :s

[BlackBox]

Hey guys,

I've just been hit with confusion over whether or not my turbos are ball or bush bearing.

The 3 turbos in question are

HTA Forced Performance 3076

Garrett gt3071

Stock fg xr6 turbo

I was just working on my xr6t and noticed when I spin it the wheel spins for AGES (it is installed on the car)

Then I get my Gt3071 and it only spins for a few seconds, I also don't think it had an oil restrictor when it was onstalled so it looks like it is bush bearing, but then the plate on the turbo says 'Garrett 700177-5023' when I look this up it looks to be ball bearing..

My new turbo is a Forced Performance 3076 and the plate on it says 'Garrett 700177-5022s' i thought this would definitely be a ball bearing turbo but it still doesn't spin near as long as the xr6 turbo..

The 3071 and HTA3076 both aren't installed on the car so could this be a reason they are not spinning as freely as the xr6 turbo?

Squirt some oil into the oil inlet or outlet of the off car turbos and try again.

After watching this video

It would appear they are ball bearing, putting oil in helped a little but still didn't spin as long as my xr6t, maybe it is something to do with it being installed on the car and it was still hot...

The bigger wheeled GT35 will probably have more momentum, too....
