that is way to high, it should read 4 and then drop to bar below that once warm, make sure u have the right amount of oil

checked the oil. its slighty above the max mark but 1-2mm.

btw im using full synthetic oil.. i think 60/10.. (Think)

could that be the problem?

That sounds like the oil is too thick which is making the pressure very high when it is cold.

Skylines like oil in the 10-40 or 7.5-40 range only and synthetic if you can afford it. The best is Motul Chrono 10-40 but it is nearly $100 for 4 litres.

  • 1 month later...

can anyone confirm with me the dodgy oil pressure gauge on my S2 r33? I have a fresh built motor with the lot internaly but about half an hour nto my first outing at the track the indicators went funny and the oil pressure now sits on a big scary 0 at idle but isnt making any bad sounds (knocking as it should if the pressure was correct).

When I rev it it only gets to just above the first bar on the gauge but all was working perfect before the indicators went oh and no fuse's are blown. also the oil pump is a tomei item for a RB26 to fit my 26 crank. waiting for my oil filter spacer to come so I can fit my mechanical oil pressure gauge.

any one have a similar problem with the R33 S2 oil pressure gauge?

erm ...

Cold start.. esp winter mornings... its normal for ur pressure to reach around 7 for the frist few mintues of driving....

After its warmed it will drop down ...

Idle around 2.

And when u drive should b around 3.5.

I have the offical figures in my room... i printed out the service manual.

thanks man but this was after some full blooded runs at mallala so yeah i think it might be a dodgy stock gauge as the indicators went as well so yet to put the mechanical gauge on but if you can give some psi readings that would be great, so when i finaly get back to my car to check it out i know what im lookin for :D

    • 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?
    • Shock tower brace is in +5Kw....LOL
