Oil Pressure To Ecu Question

I have an RB25DET Neo in an R32. The oil pressure gauge reads at 8 on idle and goes off the gauge when revved. An oil pressure test showed that the motors oil pressure is spot on, so it's an incompatibility with the 32 gauge and the RB25 pressure sensor.

My question: The RB20 and RB25 ECU pinouts show that oil pressure information is not relayed back to the ECU so it must go straight to the gauge, hence I'm thinking I can just buy an RB20 oil pressure sensor and fit it with an adapter to the RB25 motor, and this should give the gauge the correct reading without stuffing up anything in the ECU. Sound right?

Seems you're thinking is spot on, champ! :cool:

Schweet :cool:

Bubba: I have this awful desire to keep the car as close to factory in appearance as possible with the exception of a non-factory paintjob :P I'd like to get all OEM gauges working as they should. Next problem to solve, the water temp gauge ;)

water temp guage is the same thing need to use the rb20 sensor but not the ecu one.

and yeah as the others have said use the rb20 oil pressure sensor and you should be right with the oil pressure, my series 1 rb25 sensor seems to work fine with the dash but i'm sure they changed it with the neo

there are two water temp sensors one for the ecu the other for the dash, just fit rb20 water and oil pressure sensors to the neo.

      From Japan and back to Europe, my sh*tbox R34 GTT

      Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.

      Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?

      I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
