GTX2867R Ball Bearing Turbo T2 flange billet wheel

*We recommend oil pressure of the ball bearing is 40 – 45 psi at maximum engine speed to prevent damage to the turbocharger’s internals. To achieve this pressure, a restrictor with a 1.0 mm~1.5 mm orifice will normally suffice. But you should always verify the oil pressure entering the turbo after the restrictor to ensure the components function properly
