These are my stock pressures before the oil cooler install. Using Red Line 5W30 and Mobil 1 filter #110.

As mentioned previously, I never see oil pressures above 105 psi likely due to the relief valve.

I'll update after installing a 34-row Z1 kit.

What is an example of a switched circuit? I put mine to the cig lighter one however the pressure gauge wont light up. Not sure if its because the pressure sensor is not hooked up yet or what but i was testing the pwr connection before i installed everything and cant get the gauge to light up.

So to update. Hooked up the oil Pressure part, still not working. Ive tried swapping the add a circuit double checked connections just about every single circuit point...IDK.

I would avoid cutting the grommet to lead the wire into the cabin. Seriously avoid it like the plague unless you want water leaking into the cabin.

I did however i stop drilled the small cut i made on both ends to keep it from growing and then filled the cut after i ran the wires with liquid gasket RTV.

I just added RTV to mine to see if it would stop leaking.

Here is my final setup. I royally screwed myself attempting to integrate the aftermarket sensors with the oil pan. So for this go around, I opted for fittings that would attach to the oil cooler. I ordered them from Summit for $38.

It seems to me that putting the thermostat and pressure on the oil cooler would give some bad readings, especially if using a thermostatic sandwich plate.

Did this issue ever get resolved? Was the drop in oil pressure traced to a fault in the gauge? If so, is this a problem others have experienced using the AEM gauge? I'm thinking of doing this install and would like to avoid having to replace the gauge every few months because of a defect. How do the AEM gauges compare to others such as Delfie or Innovate? Thanks for any input.

Nissan told me the pressures were fine. AEM said the gauge transducers don't last long and it's the likely cause. Ended up selling the car before finding anything else out.

Spearfish, thanks for the response. Guess I won't be going with the AEM gauge. I'll check out Delfie and then decide whether to proceed or not with the install. Again, thanks for your input.

I'll just link the img to simplify.

My gauge setup. In the cubby with a water temp gauge on the left. I hated the water temp dots so two gauges got put in. See the link.

Good info. I was looking at an AEM gauge but have thought better of it after reading this write up.

My Autometer gauge part numbers.
 

For those that would like to know the potential costs involved for my build:

I paid the following prices for the gauge setup pictured in my prior post response. See below. All gauges came with sensors. Just needed to find a place to mount them. I had a sandwich plate for the oil cooler. Port was available. One problem solved. I ordered the water temp sensor adapter for the return coolant hose at the top of the engine block and installed the temp sensor. When the thermostat opens you get the coolant temp reading. It very closely follows the OBD2 coolant sensor readings. Fabricating the cubby mount and the wiring integration is not that hard. Minor cutting and drilling at best. Take the whole cubby out to do this install if you plan to keep it more or less intact, I found it to be the easiest way to work the install and not sweat to death in the Texas heat getting this done. The dimmer unit is definitely required for nighttime driving. Do not try to hook this up to the factory dimmer, it's a waste of time and just a pain.
