I'll refrain from posting in "l33t speek" on this 1.
oil: Amsoil 5W-30
oil filter: Napa gold / Wix 57356XP
oil cooler: Nissan Motorsports
gauge: Defi-Link meter BF oil pressure
sensor location: where the oil switch use to screw into the "oil pan upper"
My oil idiot switch is gone. I never bothered teeing to the pressure sensor. Disconnecting the oil idiot switch doesn't cause the red oil pressure idiot light to come on. Once my oil is up to 80°C I have the following readings:
idle: 150 kPa
cruise: ~580 kPa (My gearing keeps me @ ~3,100 RPM or >)
WOT: 640 kPa
cold start: 690 kPa
