HEY GUYS,

Just went for alil drive in my R32 GTR and My greddy oil pressure Gauge When i give it boost it starts to go all the way down, I dont think it is my oil pressure that is going down, I think the Gauge is playing up,

Does any one know where i can go to get it checked out.(Thinking it might just be stuffed or a wire lose).

Only happen when you cane it? If that is the case I'd be a bit cautious if I was you. Don't make the mistake of shooting the messenger friend.

Cheers GW

If your sure its the gauge (and you'd wanna be, or your highly risking your motor driving it)

Then it'll be either the sender/sensor is dead, or the wire has come off.

Its on the driver side

Just took it around the block before and now iam starting to think its not the Gauge,

Itz more serious:( .

You just bought your GTR for cheap?

Normally all R32 oil presure sender are stuff, in your case you've got an aftermarket so best to take it easy for now. I'm pretty sure any Mechanics can just hook up a mechanical gauge to check it out otherwise Ray@RE knows his stuff.

What u mean i just bought my GTR cheap.

when the engine is warm check how much oil you have

does the guage drop to zero ? if not, what number?

the stock cluster has an idiot light for low oil pressure so this should come on if in fact the guage is correct and you hit say near 0 oil pressure. make sure your oil pressure warning light works - turn the car to ACC (but dont start it). look for a red oil tin can icon - it should be on. if you can see it - i would expect this light to come with true low pressure

dont realy let it drop to much i back of but it goes down to around 2.

Wouldnt it be beta to check the oil level when it is cold because then the oil just seating there or no, (But the oil level is almost full when it is cold).

no check the oil when the engine is at operating temp

use the dipstick and check the level of oil in the engine

ok if you dont see the warning light at post diag then it could be dead

so you could in fact have low oil pressure under load

when you say it drops - what rpm does it drop to 2 at?

    • Thanks heaps Duncan and GTSBoy. I'll get my old man to sit in the driver's seat and turn it on and off while I test with the meter. Or maybe other way round, depending on whether he remembers where his glasses got to
    • This is the GTR fuel pump. Yellow shows 12V, orange shows earth. The ECU provides the earth to activate the fuel pump relay. The ECU side of teh relay will pull low when the ECU activates. This is the RB20 fuel pump. Almost the same, but a little simpler. You can see I indicated (above) where the 12V line goes down to the RB20 diagram on the overall diagram, whch shows both RB26 and RB20. This is where I show it coming in on the RB20 diagram below. You can see that the dropping resistor is handled differently. When the fuel pump control is not providing earth to the pump, the pump earths through the dropping resistor and thus runs at lower voltage (some is wasted over the resistor) and runs slower. I showed that "not 12V and not quite earth" portion of the wiring in a paler orange. The rest of the wiring that I did not colour on that little section below the pump would be orange when the fuel pump coontroller is providing earth. This drop is handled inside the fuel pump controller in the GTR. Regardless, you can see where 12V is supposed to be, where earth is supposed to be. The key on prime is via the ECU providing the pump for only a few seconds the switching off. You should be able to see that happen.
