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.

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.

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 :cool:

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?

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.

      new 1.5 LSD issues/concerns

      sold listed as a Tomei LSD 1.5 Way For 1998+ Nissan Skyline ER34 25GT RB25DE w/Open R200 https://www.ebay.com/itm/174006114594?campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=&mkrid=711-53200-19255-0&loc_physical_ms=108689&loc_interest_ms=&campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=71883f2ccc571356e0a757bc7adfdde2&mkrid=710-53481-19255-0&loc_physical_ms=108689&loc_interest_ms= it went in like butter all gears, alignment, back lash etc, rotation and clearances correct, and if rolling all rotates smooth and free when coasting down road , clutch in or out over 10 mph smooth... its the binding, clunking and jerking from a stop that is most concerning, also seems like its going to tear the tires off in 10 miles of normal road driving.

      What 1.5 way? There's no such thing really as a 1.5 way, just different ways of explaining 2 ways with different ramp rates. HOWEVER. In any driving in a straight line your 1.5 or 2 or 1.7 way should have no clunking at all. With the clutch fully depressed the diff should be silent (unless it's welded but I'm assuming it's not). Something aint right here.

      new 1.5 LSD issues/concerns

      By JC71 · Posted

      looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
