ive got an oil pressure gauge hooked up to my rb25det. What im interested in is what good opertation tempreture and pressure is best. The way i look at it now is when its safe to start reving out gears. when the oil is cold the pressure with move high and rappedly so if i go to put my foot down it will shoot to or past 100psi, so i know that the oil prob is not at a good pressure or temp to protect my engine yet. So at the other end of the scale 0 psi i know that i have a big oil leek and can stop befor damage.

So if any one has experiance say track work were you whatch oil pressure and temp and can offer better info then my crued understanding that would be great.

-im interested in the rb25 so anything that relates to pressure and temp of oil in these engine would be good.

cheers.

It seems to differ from car to car (depending on oil type, oil filter type) but my understanding is idle oil pressure should be around 2 bar.

When I start my car cold, oil pressure on idle sits at 3 bar. I dont give the car a hard time until the oil temp comes up to 70 degrees on the factory gauge and oil pressure has dropped to 2 bar also on the factory gauge (gtr). Seems to have worked for me so far...

    • Not sure the US can import anything other than the C34 Stagea's, but if you can and you need to to tow, DO NOT under any circumstances get an M35 Stagea. If it is just as a family car and your country/state allows it, absolutely and definitely get an M35 (3.5L if possible as it is effectively a 350Z) over a C34.
    • Punch your VIN (nm35-xxxxxx) into Amayama.com You can see everything there quite easily.
    • Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.  
    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
