I searched and I couldn't find anything about N1 oil pump in RB25DET, except for this one but it is for rb26 http://www.skylinesaustralia.com/forums/in...topic=58817&hl=

My question is can I run N1 oil pump in rb25det without any problems and without any modifications?

If you are using one please share your mods and opinion on it?

RB20/25/30 cranks have narrow oil pump drives, same as early RB26's.

Later model RB26's have wide flange oil pump drives on the crank

N1 = N1 (production cars circuit racing class) homologated part for GTR

There is no such thing as N1 homologated parts for GTST (or GTT)

Personally I would never use a high pressure N1 oil pump on a crank with a narrow drive flange, I have seen too many cracked oil pump rotors with obvious signs of angled narrow flange loadings.

You can get a crank collar (Proengines make one) that converts a narrow flange oil pump drive crank into a wide one. The crank needs to be machined to fit the collar, so out of the car.

:P cheers :(

can anyone tell me the size of a short verus long oil pump drive on the front of the crank. i brought a new rb26 crank 18months ago and want to measure the drive before i refit it. i assume the all new cranks from nissan would have the wider drive but want to double check. pics or measurement would be nice.

cheers

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
