oil pressure gauge
 

can anyone tell me how to install an oil pressure gauge on my frs?

The car has both a oil pressure switch and a oil temperature sensor just in front of and below the oil filter.

I believe the one on the left with a single wire going to it is the oil pressure switch.

I would imagine you can probably take that one out and install T or Y junction and then bolt the original switch as well as your aftermarket sensor to the junction.

I plan to pick up a dual gauge (oil temperature and oil pressure) once somebody comes out with a good looking gauge pod.

Think you for the info.

So when I am ready to install Oil Temp gauge, which one should I Tee up?

Left or right? (I saw @getbent said you should tap to the one on the left, just want to confirm). Also, anyone know what size fitting is needed? Links? Pictures? Thanks!

Edit: @onemorelap where did you end up connecting and using what? (Longshot since he has not logged in since August.. but who knows!)
@PrimeMotoring @Rev Works may be able to help too.

Here's oil temp gauge that reads through the OBD2 connector. No need to wire in another sensor as uses the OEM one. Expensive but looks great.

Mounts in drivers side aircon vent but still allows the air flow

I like the look of that. Too bad it isn't Oil pressure and Oil temp, then i'd buy it in a heartbeat.

I just want the vent pod.

The one on the left is the idiot light oil pressure switch. It is 1/8 BSPT or PT. You usually do not want to screw a tee directly into the block, a lot of guys will use an extension hose.

Thanks to @Supermassive for the pics!

I believe this is a GREAT location for the Oil Temp gauge sensor.

Thoughts anyone? @PrimeMotoring @Rev Works @Dave-ROR @P&L Motorsports @Pure Automotive

On the FBM kit I used a 3 way junction at the factory oil sensor on the front of the motor. I think the reason they used that for the turbo feed is because the coolant lines for the turbo run under the intake pipe where that port is. I would either use that port or run off a sandwich plate in combination with an oil cooler.

The 3 way junction is 1/8" NPT? Can you take a pic? :-D thanks!

Is that a standard Subaru oil gallery plug in the pic, if so it would be a good place to tap for oil pressure. It is what most Subaru guys do on th EJ engines since there is an extra unused plug. You just buy the oil pressures switch plug which has a 1/8 PT hole in it to replace the solid plug.

Again I would not use a Tee screwed into the front ports, those things have a tendency to crack under repeated stress without much support.

You can even buy this one which is threaded for NPT and not BSPT. Depends on the gauges and send unit you are using.

Or just get the whole relocation kit since the pressure senders are usually pretty large.

This Tee I would see working but it's expensive

Thank you so much for the suggestions. I believe it is the Standard Subie oil gallery plug. I got this AEM Oil Temp gauge. Still need to wait for gauge cluster, but will update when installed.

There is DIY on to set up a guage like this. its Pretty straightforward and easy to do. just need a 60-62mm guage and some double sided tape

And I assume an oil temp sensor or is there another one that will use the OBD2 connector or the OEM one?


.

Those brass tees are notorious for cracking at the threads and is exactly what I was talking about.

I'm going with the gallery plug. Thanks a lot for your help!!

Hi guys, I'm planning to install an oil pressure/temp gauge and I was wondering where I could get a more accurate reading. Which is better to put into the galley plug, the oil pressure or temperature sensor? Or is it okay if I just run both on a sandwich plate? :bow:

@Sportsguy83 did you ever get this finished? Thinking about getting the FastWRX gallery plug / sender relocation kit that was posted earlier for myself.

I'd like to do this DIY as well. I'm deciding to install the sensor in the unused gallery plug. Anyone know where I can wire a defi gauge?

I was reading on NASIOC, and some WRX guys are were replacing the idiot light switch with their pressure senders, basically unplugging them, and they didn't have any CEL or issues? Has anybody tried that on our cars?

my plan at the moment is to use that relocator kit posted above, remove the idiot light switch, plug the SS line to where the idiot light switch was, run the SS line to a Tee, then plug in both switch and pressure sender into the T. any real problems with that setup?

So which one was it? I think it's the one on the right but the AEM fitting I have doesn't fit. Is there an adapter I should use from subaru? Thanks.

I didn't use either. I used a plug on the top of the block.

I believe left is oil pressure and right is oil temperature.

Reviving this thread, so as to not start another one. I am about to install oil pressure and temperature gauges. I am planning to use the galley plug for temp, and the stock pressure sender location for oil pressure. My question is, can I just toss the stock sender and ground the stock sending wire? I don't want the oil pressure dummy light to be on all the time on my dash.

On the WRX the stock oil pressure dash light switch is a normally closed grounding switch that opens and breaks the ground when it senses 2.5 psi of oil pressure. Does anyone know if the FA uses the same type of switch?

This document is what gave me the idea

You can toss the stock oil pressure sensor and just tuck away the stock sender line. No need to ground it at all. I tossed mine and tucked the wire, installed a real pressure gauge in the same spot (off a tee, since it's also my turbo feed) with no problems and no nanny lights :)

I like the sound of that! Thanks for the info! Now just waiting on the galley plug in the mail and I'll be ready to install :)

Could you post a pic or two of your setup?

where are people mounting their gauges? I see the a/c vent gauges, but honestly with as hot as it gets here in summertime I do NOT want to block any airflow to me...I feel like the a/c can't keep up as is...

You can get the A pillar pod although I cant remember who makes them. From the crash test videos I have seen there dont look to be any airbags in those pillars. The other spot is that passenger side dash. Also the cluster hood comes off but now sure how it affects visibility...

Sent fabulously from a fabulous phablet in the hands of a fabulously dressed phantom with a fabulous phone...which is a fabulous phablet.

@Fizz, here's a pic of the setup under the hood:

I've got the brass T supplied by FBM as part of the turbo kit. It splits into the turbo oil feed, and a grease gun extension to relocate the pressure sensor as you can see in top right. I followed this guide loosely: http://forums.nasioc.com/forums/show....php?t=2301886

You can see the original oil pressure sender wire with the green wire. It's just hanging out and I zip-tied it out of the way.

@Basket Case, here's a pic of my setup:

There's a guy on Mazda forums called block8head (you can google him) who makes these custom pods. They're a bit expensive, but they replace the stock window defroster insert and look really OEM.

Could I get a pic of those gauges on? I'm looking at getting basically the exact same ones and have the same pod you do. I just haven't been able to decide if I can tolerate LEDs or if I want standard needles.

Took a video since I figured that'd be a decent way to show on vs. off. They're very comparable to stock dash lights, not bad at all. I have them setup to dim once you turn on the lights (or they turn on from auto lights) so they dim appropriately. Unfortunately there's not a nice way to dim them more if you like dash lights to be very very dim... only the AEM gauge has that. The innovate gauge is basically on-off dimming from what I can tell.

Where did you connect the innovate gauge for power and dimming?
And what size is needed for the fittings?
Going to get the innovate temp & pressure gauge too, and this look like a great idea to put the big pressure sensor :thumbup: also where did you put the temp sensor for the innovate gauge?

:thanks:

I would also like to add an oil pressure gauge. Exactly how do you connect it on the engine side? What sort/size of adapter do you need to connect it to where the stock pressure sensor is , and were do you buy the parts?

Temp sensor went onto the top galley plug. You'll need the galley plug adapter to do that one, here's the part #: http://www.rallysportdirect.com/Suba...il-Galley-Plug

The pressure sensor I literally followed the tutorial linked exactly. Keep in mind, I had mine off a 90 degree brass tee with my FBM kit. Not sure if it mates properly to the block. I believe the thread is BSP and the innovate gauge is NPT (or visa-versa) so you want to be careful you don't crossmate them. You may need an adapter.

Dimming I pulled off the head unit wiring harness. There's a few spots, but that one worked for me. I wired the innovate and the AEM to the same tap.

See this topic: http://www.ft86club.com/forums/showp...9&postcount=16

For power there's a bunch of options, I don't remember where I wired mine in to.

Hope that helps!

Quick question, can a male bspt be used in a female npt?
Or do I need to get adapters, I have searched around but get mixed answers..
And ofc I will use teflon tape..

@Teclis

check this out for power: http://theattack.rallysportdirect.co...r-ssubaru-brz/

That's what I did and it's so much easier than tapping over at the ECU like a different wiring diagram I found suggested. I had to run the cables around 6" since they were mounted over the defroster vent rather than the width of the car.

Also, instead of using a galley plug and disconnecting the stock pressure sensor, I went with a Mishimoto sandwich plate. It was on Amazon for less than $30. My goal was to keep things all together.

Thanks man! I'll check that out now!
And I was thinking about using the relocating kit to the gally plug and connect the pressure sensor to that, so I'll keep stock pressure sensor too.. and then have the temp sensor connected to the mishimoto oil cooler housing, after that got 2 1/8 npt spots to put sensors :party0030:

But did you connect both sensors to that housing? any adapters needed?
What gauge are you using? :thanks:

Everything from the Innovate gauge fits like a charm with the Mishimoto sandwich plate. No adapters, just some thread tape. It has 3 bungs so I still have a spare although I can't think of a reason I'd need it. It's meant to be able to hook up to a custom built oil cooler kit and have a sensor.

You could just use your oil cooler housing, but remember the wires will all have to be run that length as well. I'd recommend some loom to keep it safe and tidy.

I have the pressure sensor in the back so that it's out of the way and the temp sensor towards the back as well. that way the oil fill tube could still be accessed easily. I didn't want to have the sensors both facing the front of the car cause that would look ugly and have wires where a forced induction kit would usually put some equipment.

I have the Innovate gauge for oil temp and pressure and the Defi gauge for boost. I also have the P3Cars gauge for a bunch of stuff.

@Teclis
Hey I just thought I'd mention that the Innovate gauge really doesn't dim all that much. It does dim to be sure. But I wouldn't say it gets half as bright exactly. The Defi on the other hand dims a whole lot.

I don't think it's too bright at night. It's just a personal preference. And I needed 3 gauges within 2 pods. It was the best option I could find.
