Ok, Im using a stewart electric oil pressure, the sensor is connected to my greddy oil relocation kit by the oil filter.

On cold start I dont get any oil pressure at all, during driving conditon it only goes to maybe 20psi no more but my oil temp gets up to about 180-190 when warms. It drives fine, boost fine and idles fine. Im also using moble1 5w30 syn. oil.

Any inputs, or my gauge is reading unless my wiring is bad somewhere.

Also I did some search and noticed that people using the greddy oil relocation kit seems to have a oil pressure problem.

Any one has an input on this?

I'm using an greddy oil filter relocation setup but my oil pressure sender is by the oem location. My oil temp is in the oil filter plate. I have a slight dip in oil presssure, but not as much as you're thinking.

You said your using the oem for the oil pressure, where is that located? Is it next to the oil filter?

Its where the oem oil pressure dummy switch is located: to the top right of the original oil filter location; just to the left of the alternator. I'm using a electronic greddy oil pressure sender in that spot.

probably has to be closer to the block, or maybe your gauge is faulty which i highly doubt.

First and foremost, 5W30 is too light for an SR. Getting 20 PSI only while driving is BAAAAD.

Redo the grounding on the car. All electronics should run to a common ground on the chassis.

Yea i was checking my connection to the sensor and everything seems good. All my gauge is grounded to same location, and they all work fine except my oil pressure.

How do you guys fit the oil pressure by the block if I already have my greddy sandwich plate there?

Reroute a new line?

Just gotta find where the oem pressure sensor is. Looks like this:http://is.rely.net/3-99-10194-l-byYYjFTHf5mNb9efTbOtA.jpg
