you should not use and oil restrictor on a Garret ;) according to the one who reconstructed my GT30 an oil restrictor was the cause of the turbine failure. This turbines have and internal oil restrictor

But supposedly the Ball bearing need a restrictor :
"Ball Bearing Turbo

Ball Bearing Turbo An oil restrictor is recommended for optimal performance with ball bearing turbochargers. Oil pressure of 40 - 45 psi at maximum engine speed is recommended to prevent damage to the turbocharger's internals. In order to achieve this pressure, a restrictor with a 0.040' orifice will normally suffice, but you should always verify the oil pressure entering the turbo after the restrictor in insure that the components are functioning properly.
Recommended oil feed is -3AN or -4AN line or hose/tubing with a similar ID. As always, use an oil filter that meets or exceeds the OEM specifications"
