Pick 2 gauges for turbo build.
 

I will be able to mount 3 gauges (1 AC vent and 2 defroster pod) when I do FI for the first time in my life next month. I will be running an AEM wideband failsafe in one of the spots. Not quite sure which are the next two most important gauges to mount for this application.

1. Oil Pressure
2. Oil Temperature
3. Coolant Temperature

This is probably a noob question but any help would be appreciated.

AFR/boost combo gauge, then oil pressure and/or temperature.

they have a dual gauge for oil temp and pressure, then from there egt would not hurt.

Solid advice from @Ross. Boost/AFR, Oil T/P, EGT...you're now monitoring the most vital things you need to monitor.

Thanks for making it an easy decision for me.

FYI @Cheeseballs EGTs can be tricky since you need to have a bung for the thermocouple - are you still on the stock header? Stock header will require drilling/welding a bung to use EGT whereas most aftermarket headers (of quality) come with at least one bung, if not more. Unless your gauge can accommodate four sensor inputs, you're going to want to put the sensor in the hottest exhaust runner; traditionally for the turbo Subarus this has been the runner from the #4 cyl, though I can't with any veracity make that claim on this engine.

I'm getting PLX gauge, which either plugs into your car's OBD port, or you use their modules for whatever you want to monitor.

Each gauge can show a bunch of different hings, you just scroll through to whatever you want to view.

innovate oil pressure/temp combo gauge, innovate water temp, aem failsafe afr/boost,

IMO

AEM Failsafe, EGT gauge and an oil pressure.

Temp is important, but not quite as important as your pressure suddenly falling off the map.

Again, IMO.

I went with 2, the AEM failsafe and Innovate MTX-D for Oil Pressure and Temp in 1 gauge. If I were forced to pick a 3rd gauge, it would be water temp

The OEM water temp sensor in your gauge cluster is effective enough. I might go with a fuel pressure one if I was running a heavily modified fuel system or a high boost setup that taxed the fuel pump.

When this goes in to production in the next couple of months it will be an excellent option. AFR, Boost (up to 44psi), boost control, boost cut by RPM and/or AFR, programmable shift light, and 0-5v analog output for AFR. You can also log solenoid duty cycle, manifold pressure, AFR and engine RPM to your laptop or iPhone provided you use it in conjunction with the OT2 device. You can also daisy chain this device with our other MTX-D series gauges to also log your oil pressure, oil temp temperature, etc. A ton of functions for a single gauge.

Logging from ODBII port?

Kinda off topic, but is there some other oil gallery port in the engine aside from the one right beside the AC compressor? I already have my oil pressure gauge hooked up to that port, and I'd like to run an oil temp gauge as well.

seconding this.

OBD2 or dedicated sensors? Im really not a fan of reading off the obd

I'm not sure why the PLX gauge isn't used more. It can operate off your OBD port, and/or uses it's own sensor modules, and can display every parameter needed.

I'm getting oil temp, oil pressure, boost, coolant temp, and can add AFR, EGT, fuel pressure, and read all of these by simply pushing one button and scrolling through.

The only disadvantage to multiple gauges is it only displays one thing at a time.

I plan to leave it on boost or oil temp, and check the other values periodically.

No, this product does not require an OBD2 interface. It will ship with a custom spec solenoid, 4BAR map sensor, and a WB02 sensor. You can optionally use it in conjunction with our WiFi OBD2 device, the OT2 but it is not required. As mentioned you can also chain it with other Innovate devices to log via the OT2 to your WiFi enabled Apple device, our PL-1 SD card logger or directly to a laptop.

The two popular ones are to tee off of the OEM low oil pressure sensor on the front driver side of the engine or get a fitting to replace the large plug on top of the engine below where the intake enters the throttle body:

With oil temp gauges you really have to be careful that you are reading the temp of the oil and not the temp of the fitting or metal. I normally like seeing those in the oil pan.

I'm about to put my temp sensor in the pan, I don't like how it fits in the sandwich plate.

Thanks for the info! I already have that oem Subaru oil gallery plug hooked up to my oil pressure gauge. I'm having a hard time looking for a decent fitting to tee off the stock oil pressure sensor. I've only seen brass ones which are said to be weak. I know I could use an oil filter sandwich plate, but I'm already running one for my oil cooler and I don't want to stack another one

I think drilling and welding a fitting to your oil pan would be a good option or an aftermarket oil pan with a fitting already installed would be a better option.

An inline sensor manifold is another option, mount this on the hot side going to the cooler. Preferably as close to the motor as possible.

Im trying to reduce the amount of Tee's and adapters needed since every connection is a possible leak.

Never seen one like that. Great idea since he is running an oil cooler.

You should make a sensor that can replace the factory oil pressure sensor, giving two outputs, one to your gauges and another to the cambus simulating the factory sensor. Make an oil temp gauge that can do the same and you'd completely eliminate the need for all these T's.

Personally I think gauges now a day are pointless.

Set your ecu to not allow certain parameters and let it do its job.

An ecu can react much faster than you can, thats if you're even looking at the gauge when something goes wrong.

^^in worst-case, absolutely, fail-safes are awesome. One of the pluses for having gauges as well is that it's comforting having something there so you can have an idea of how things are running without having to log things to review later. Also helps you learn your car, and the state it is likely to be in, in a given situation. Constantly logging and reviewing is a pita.

Thanks for showing this. $60 isn't much to pay to reduce the amount of potential leak points.

I'm getting the 200 model with OBD2 and it can show 4 param at a time. Slick! Better than the p3cars gauge.

hey
i will be installing a turbo kit soon, but i dont have any experience. I dont know these AFR, EGT, wideband, failsafe terms, how they are measured etc.
can someone explain or post a link where i can read and learn about these please.
i will need to watch my oil temp and pressure for sure, i only know that. oil temp should be under 100C, how about oil pressure? and do i need any measurement devices and drilling at oil pan? I will get oil cooler for sure, so i guess they work like radiators so it will have a pt100 anyway i guess so no need to buy i guess.
need info, thx
