idle and at 2000 is about right...the 6000rpm on pressure can rise upto bout 5-6 cant see the marks properly..but for 6000 is maybe another 1kg or 2 more than 4kg...oh well the only problems with pressure would be if you are using a high rating oil like 10w-60w my pressure jumped about 3kg on each spec on idle it was about 3kg. The stock gauges can be sometimes faultu too.

sorry to bring this old tread back but i saves me makeing a new one.. i have a R32 and at idle the gauge will sit at just under 4 and after it warms up it sits just under 2. then after about 10mins or so of driving when stopped again the gauge sits about 3mm from the 0 mark and on the highway it sits just over 2??? i'm using castrol magnatec 15w-40. could this just be a dead sender or gauge the car doesn't seem to drive and different.

seems to vary a bit between models. and it's unusual to hear about a motor being damaged by lack of oil pressure - unless of course it's being used on a track and suffers from starvation under hard braking or something.

Mine will get pretty close to 0 at idle, with a thin oil like 5W-40. I tried some thicker synth oil and it held pressure a touch better but revability and cold start were affected. Now that it's coming back into winter again i put 5W-40 back, and I reckon thin oil's the go in any case.

My unprofessional opinion is not to worry about it, just work out what's normal for your car and if it does anything different THEN worry. :)

i'll get a oil pressure gauge after my cooler install and see what the go is.. the car has 160,000 kms on it and has been serviced every 5,000kms ( that what the previous owner said, i hope ) and the head is only 60,000kms old. could it be a oil pump problem?

I got my '93 R33 turb serviced recently and since I got it back the stock oil pressure guage doesn't seem to be working. More specifically, it is sitting on 0 all the time.

I can't think of anything that they may have done that would have damaged it but surely I'm not driving around on 0 kg/cm2 oil pressure. The car is running fine.

Before the service the oil pressure guage behaved normally.

1-2kg for idle

4-5kg for boosting

Any ideas on what I should look at to fix it? (I have checked connections into the guage). Is there a sensor they could have knocked or something like that ?

Thanks.

Make sure they haven't disconnected the sender connection on the oil filter block, under the intake manifold.

Mine goes off the dial when cold and drops to 2 at idle when fully warmed up and will go over 6 on the track at full noise.

It all depends on how many kays the engine has done and what your oil level is.

I let my oil level get down too low and it dropped to those low pressures, then a big end bearing ran. The bearings were old tho.

      It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪

      And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil

      Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.

      Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.
