Oil pressure sensor relocation
Hey guys,
I want to add oil pressure and temperature sensors for datalogging, in addition to the stock oil pressure gauge.
I don't want to tap my oil pan. I don't want to use an adapter/tee fitting on the stock gauge location because that **** cracks and leaks.
What I was thinking is something along these lines -
Miatacage.com. Oil Pressure Sensor Relocation Kit.
Replace the stock sensor with a braided line that goes to a distribution block of sorts and feeds all 3 sensors (stock OPG, oil pressure, temperature).
Has anyone done it or used that kit? My concern with that is the fact that the sensors won't be in direct oil flow, so readings might be off. Alternative would be to do an inline distribution block on the turbo feed side. I don't really like that idea because oil failure points right near the turbo hot side is bad.

The oil temp is harder, as a manifold like that wouldn't see any flow. You really want to put it in the oil pan, as much as that sucks, but the other option would be to put it in the feed line to your oil cooler somehow.

The temperature sender, I could put it inline with the turbo oil drain.

I've been looking into this as well. I'm swapping my factory OPG for a 0-100psi VDO or similar using
I modded the factory NB gauge with resistors, but you may not have to in a early NA chassis.
Then I'll spice off the gauge line to the MS3 and have oil pressure readings in the datalog stuff.
Then I should have an actual gauge in the cluster and a working input for the MS3. Bonus if it works in ShadowDash.
PS: I believe the early NA cars read psi on the factory gauge so a 0-80psi 180ohm sender would match the factory psi's better. A 0-100psi 180ohm would throw the scale off I think.

for cheap. It should output off resistance vs oil pressure. I modded the factory NB gauge with resistors, but you may not have to in a early NA chassis.

You can also add a 1/8" NPT fitting on the oil cooler lines, or the sandwhich plate (if you get one of those).

Its usually for more than one gauge or computer reading.
For example I have a sensor for a fail safe ight and engine killer. It will light up at a set pressure and kill the engine if it gets lower than that. A second sensor for an aftermarket pressure guage and the factory sensor too. I dont so much need the factory setup but Im not taking the time to remove or swap that gauge and I dont want it to be a dead spot in the cluster.

It seems (though I haven't tried it) that you could use a single sensor for all of those things provided only one of the devices has a "pullup" resistor. It's easy enough to have a Megasquirt just read the analog voltage at the sensor or the gauge or wherever you want to tap in.
I suppose it wouldn't be possible to use two device that require different sensor calibrations, perhaps aftermarket and OEM gauges, but a programable ECU or datalogger should be able to work with any sensor... I would think.

Hey Lenny, Did you ever get anywhere with this sensor relocation? My old oil pressure setup will not work for me with the new turbo location and i still want to see if i am about to destroy my bearings.

I used this sender. The VDO gauge was from a Volvo that I had lying around.
