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 1.0mm orifice will normally suffice, but you should always verify the oil pressure entering the turbo after the restrictor to ensure the components function 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.
- OIL LEAKAGE SHOULD NOT OCCUR ON A PROPERLY FUNCTIONING SYSTEM IF RESTRICTOR IS NOT USED UNLESS THE SYSTEM PRESSURE IS EXCESSIVELY HIGH.
There are many products to help you achieve the recommended oil pressure to your turbo. Oil restrictors are threaded into the oil inlet and slow the oil feed based on the diameter of the orifice
