Pick 2 gauges for turbo build. - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Cheeseballs · 03-24-2014, 11:20 AM

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,

Deadspool · 03-24-2014, 01:40 PM

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.

protpibe · 03-24-2014, 02:17 PM

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

King Tut · 03-24-2014, 02:25 PM

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.
