Have a garrett gtx 3071r they sent a restrictor in the oil intake being this a ball bearing turbo they do not need lots of oil but continuous. Question is if you run a 10-14psi pump can the restrictor be taken out. On garretts web sit they say use the restrictor when oiling 30psi.

I use no restrictor with the oem injection pump . no idea on the electric units.

Is there such thing as too much oil?
It just re-cycles.

I just ment more than you need, if you cycle the oil 20 times more than needed you will also raise the oil temp. Its like using a 3" fire hose to fill a pop bottle, not needed.
Well using the restrictor a inline filter should be used then and then there is no way to tell if the turbo is getting oil other than a pressure gauge on the outlet of the pump or some sort of flow switch.
Ball turbos should have no pressure at the outlet,,zero.
so far so good,, I get scared of the restrictor in winter as well as the sled environment itself..
Useing clear line allows me to see the oil is there,,, moving not so easy to see, but there..lol
also use straight 5 wt ,, again so far so good.

I have a see through filter before the pump and I spliced in a clear piece of hose right before the inlet. This way I know That I
Don't have a blockage anywhere in the line
All good points turbo mount, small tank,filter, pump,outlet, pressure switch with light, inlet to turbo with egt probe maybe have a spare point on my system. For cooling the turbo going to feed outlet of i/c thru turbo and back to exchanger this way i can have a post cooling on it when the motor is turned off.
I see what you mean but by recirculating it more it is also cooling faster and there is more oil to do the job. So it gets more passes at the hot parts but it is also getting more passes to cool as well.
Lack of flow will kill the bearings, too much flow certainly won't hurt.
Anyone ever tested how long a ball bearing turbo will live if the oil pump quits, or the line get plugged? everyone says they don't need much oil, but how long will last? a couple minutes, a couple hours ?? 
Actually yes, there is only a split ring that seals the turbine shaft from the outlet. Its possible to push it out the exhaust and also into the intake track.
At an idle that might be an issue, but under load highly unlikely you will have that much flow.
Most turbo's will leak a little oil at an idle because there is not much pressure holding that seal shut.
I've never seen a failure from too much oil, seen several from not enough.
Depends on your oil pump and drain size. I've had this very problem myself. Your right, you won't have a failure from too much just makes a mess.
