R32 Gtr Oil Pressure

[GTROB]

Just wondering what oil pressure a R32 GTR will run at idle and revs when hot and cold. Also what eng oil temp do they usually run. I thinnk my oil pressure is a little low and the oil temp seems to be alot higher than it usually has been. oil temp is up around the 75 to 80 deg even on cool nights. It has a big oil cooler on it. The oil pressure is below 4 kg/cm3 at idle when cold and is back to near nothing when hot. I havn't checked it with a mechanical gauge yet but will be maybe this week end.

Chuch another gauge on it, the Nissan senders are renown for failing. A common cause id the bolts holding the two halves of the oil pump together coming loose

How much oil do you have? How old is it?

I just started a brand new engine (with forged internals etc), and at idle when cold the oil pressure is about 6.5kg/cm3, and drops to just under 4 when hot. Ive only idled it around the local street because its untuned though. The oil temp doesnt go above 80 degrees when hot, with a large oil cooler. Both gauges are greddy expensive ones.

...oil temp is up around the 75 to 80 deg even on cool nights...

Rem with the OEM oil / water heat exchanger, your oil should never get to below that of your coolant temp.

this is what nissan say

^ on my rb26 with the oil cooler i have to the dipstick reading a bit over the H mark or i loose pressure in high revs.

oil pressure should read about 2kg/cm3 when properly warmed up.

buy a aftermarket gauge so u get accurate readings

Thanks for your help guys thats puts my mind at ease.

well where on this topic ive had my motor rebuilt bout 6000km ago when its cold the needle goes off the clock and when its worm some times sits over the 4 mark or ewven higher is this good?

[NoFX_Hardcore]

I would like to know the same question boosted_32. I have an n1 oil pump and my idle is about 1200rpm, when cold it sits on 8 bar and when fully warm sits on 4bar......

Is this normal?

[Gtrgodzilla67]

thick oil ?

[Duncan]

this is what nissan says for standard

[NoFX_Hardcore]

Mobil 1 (5w 50)....maybe I should use 10w40?

[c0ris]

when cold at startup mine sits on 6 on the defi....on the stock gauge its on 4

when warm at idle mine sits on 1.5 on the defi....on the stock gauge its on 0

dont listen to the ppl tellin u to change ur oil. its not ur oil. its the sender unit.

mine also did the same.. i shit myself real bad when i first noticed it.. it was @ 0 @ idle.. but after a few days i noticed that even when its on 0.. the light doesnt come on.. u know why??

because they run 2 seperate systems. 1 fails.. the other doesnt. put an aftermarket gauge on it and ull see the difference

Hey All, I think I need some similar advice to this post.

I just bought a GTR in QLD that I have driven back to Melbourne over the last few days. I never really paid any attention to the oil pressure to begin with, but noticed today it was on zero - but the car seemed to be performing fine - great even! it did over heat on me yesterday somewhere in central NSW but it seemed fine again after a rest. I have noticed it seems to be running hot, & im not sure why.

When boarding the boat we were in the waiting line with a lot of idle, stop start etc with the engine getting rather warm. The oil pressure light then came on, with it barely idling, coughing & spluttering. I turned it off for a few minutes, then it was fine again & didn't miss a beat getting onto the boat.

I write this now sitting in the bar with a beer, freaking out! im hoping the oil pressure issue is related to the over heating, & that is hopefully something simple like the thermostat?

The motor has been rebuilt & I have all the receipts for it, I am living in hope its not the motor...

what should I be checking?

[Hadouken]

Im thinking if oil pressure light came on while it was spluttering might be that it almost stalled itself and as such dropped oil pressure enough to set off the light, but probably kicked itself back to life.

Have you checked the dipstick? Overheating could be a lot of things and it will need to be narrowed down.
