No i dont have a oil pressure gauge fitted to the car but i do have one on my cossie that is off the road i could grab it off??
its worth checking as if your running a small restrictor and your oil pressure is on the low side it could be starving it, ive just fitted a 1.5mm restrictor in my r33 as the turbo feed was seeing 90 psi
lol
if a 1.5mm restrictor still doesnt supply 40+ psi then the oil pressure is well down ime.
most people fit 0.6mm restrictors in the paranoia of overflowing it with oil and can end up under doing it and screwing the turbo up anyways.
