Hey everyone.

I've been thinking about getting an oil pressure gauge for a while now... i know the standard ones in 32's are completely unreliable, and i've also heard that the RB20's often die because of bad oil pressure.

So i'm currently thinking of getting one of those 3 gauge holders to go under my stereo head unit, and i'm trying to decide what gauges to get and where to get them from.

I'm thinking Oil pressure is a must... Possibly get an air/fuel ratio gauge (with a wideband sensor) ... and i'm not sure what to get for the 3rd spot.

I already have an aftermarket boost gauge (which was cheap and isn't overly accurate, but it does the job) so i don't need one of those.

So in summary:

What 3rd gauge do you recommend?

Where is a good place to purchase gauges?

Do i need to replace the sensor for the oil pressure gauge or just the gauge itself?

Thanks,

Steve

[ ps. yes i have used the search tool to try and find some answers to the above, but funnily enough searching for gauges brings up a million results ]

If it was me.

1- Oil temp / Boost / Oil Pressure / AFR

I want that combination for my car.

2- Just jap or shift performance. Both located in sydney, both have online shopping

3- Yes you have to change the sensor over, the new sensor will have a different electronic signal (voltage drop) for different temperature ranges, so the gauge will only know how to use the voltage signal that the new sensor uses.

Oil Pressure/Oil Temp/Water Temp

Defi do a nice 3 gauge setup with those units in it. Expensive, but work very well. I tried a few different brands out before i bit the bullet, and they are worth every penny. Otherwise you could try another jap brand or even the electronic versions of autometer

It's not that standard gauges in most cars are not accurate, they're usually set to sit in the middle at acceptable temps. Once it starts getting toward the too hot range it'll go up.

Most people just prefer to know exactly what the temps are doing.

this is where I bought mine from, I believe they are genuine too, hope this helps

I grabbed oil temp, exhaust gas temp and oil pressure,

    • Hi everyone, I've been wrestling with this for a while now and have been trying to find out the cause. For context, the turbos used are Garrett 2860 -5s, the BOV is a BNR32 HKS SSQV IV kit, the car is currently tuned to ~470 whp on 17.5 psi. The car drives normally, pulls well when it doesn't happen, and I can replicate it fairly easily. It does not sound like turbo shuffle or flutter. The engine has only a thousand or so miles and has had this behavior since it was completed. After my engine was built for my R32 GTR, I noticed that the car now sometimes makes an air discharge sound on what appears to be positive boost pressure that sounds really similar to a BOV. I had thought that it was a BOV issue but even when replacing it with a brand new unit, the sound persisted. It seems like it's coming from the passenger side but I may be mistaken. The closest scenario I could find was this post here https://www.gtr.co.uk/threads/maybe-a-boost-leak-opinions.147955/https://www.gtr.co.uk/threads/maybe-a-boost-leak-opinions.147955/ started by @yakshii and it sounds very similar. As in, at partial throttle once I reach positive boost I begin to hear the same psh psh psh psh psh sound like air is leaking somewhere when I keep the throttle in the same position. It most commonly happens in 4th gear at around 3-3.5k RPM and 5th gear around 2.5-3k RPM, which seems to coincide with normal positive boost thresholds. It might be similar to what @Austrian GTR mentioned about his own HKS SSQV. Notable difference would be that when he applies more throttle when it happens, it stops. In my scenario if I apply more throttle during this repeated psh psh psh sound, the cadence of the sound gets faster and louder rather than stopping. If I lift off slightly and apply throttle again, it will normally stop and pull without issue. I've checked all rubber couplers to ensure that they are tight, but have not gotten the opportunity to properly do a pressurized boost leak test. If anyone has had similar experiences or thoughts on what might be the cause, I'd be very keen to hear them. I also have a video of it happening from inside the cabin, if that would make it easier to understand: https://youtu.be/2zqZXcx8jbA
    • I'd want at least $40K for mine, but thats easy to say cos I'm not selling anyway.
    • That's incorrect. We have 4 seasons, consisting of pre winter, winter, post winter and a small glimpse of hope! 
    • I spotted a black C34 in Mittagong this morning!
