what oil pressure does the rb25det run at, at tickover and through the revs please if anyone knows?

I have f**ked my engine by having a blocked oil strainer, (don't ask, long story!) but at no time did the oil warning light come on. I am getting a replacement engine fitted and thought of fitting either a depo gauge with a settable alarm on it or a higher pressure oil switch like this

This is the cheapest option and at least the light would work then when there is still enough pressure to save big ends and main bearings etc. Or is the tickover lower than that?

I do not want to be caught out like that again. Some vehicles have the oil warning light fitted to a oil level switch which is totally useless in my opinion as you could have a full sump and no oil pressure!!

When I relocated the oil filter and installed the gauges I fitted an oil temperature and oil pressure gauge.

On start up it runs around 50/60 psi, when hot and running it drops to around 45 psi. At hot idle its about 20 psi.

Temperature is about 85 with normal driving. Given a real good push up the Mountain it can get to around 110.

Have always used Fully Syn Nulon 5W-40 with 80k addative

After fitting the F/F plenum I still get a gurgle from the back of the motor after a hard run, but if I let it run for a minute or so, stationary,

it does not gurgle. Have got an oil cooler to fit soon, but wanted to get some braided lines so it looks better.

Link sell an oil pressure sensor which when wired through the link will turn the engine off while oil pressure is below a given figure for the rev level. Sadly for you its not much use without the Link as the switch off point needs to be variable. If you set it to trigger an audible alarm below a certain figure that would probably be a pain at idle and on starting up.

I have got a depo oil pressure gauge and sender on the way, a bit starwars for my liking but it'll do what I want, will mount it in the centre top right air vent, already fitted r32gtr gauges below the aircon but they are boost, oil temp and volts.

    • I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.  
    • Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days
    • It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
    • I assume clearances were all a-okay?
