Still got me stumped!! I might get NDI to test the gear for cracks and might use it if I rebuild the eng again!

Haven't seen anything like it before, 85mm outer gear dia, nothing similar I have searched. It was sold to me second hand as an N1 pump....

Alloy pressure relief valve plug, not anodised.

Oil pressure outlet is cast smooth, not drilled and machined out and plugged.

If anyone knows the type or who made it please let me know!!

85x12mm Gears....and was sold to you as a 'Used N1 Pump'......

I think what you have there my friend might be EXACTLY THAT......A REAL Group N or N1 Race Pump from Reimax (Oldsckool Reinik Pump?), not the 'N1' Pump from Nissan.

Easy to see how someone could get confused maybe ? (seller)

Looks like you struck gold with that one.......

Also, you say 'looks like a thin-drive crank was used on it'.......?

Probably a dead givaway that it was an Early BNR32 Race Pump before the crankshaft change :huh:

Share pics of the FRONT of it please.

What a SCORE !

I hope the person that sold it to you, sold it cheap.......and is reading this now :thumbsup:

THAT is truly a piece of RB history......and probably has enough life left in it to make it out for round 2 for a little more history making......lol

I wonder if the backside stamp '03' means Pump#3 off the assembly line ?

Well, Good Job !

Now Oil it up nicely before you put the cover back on, Locktite (or whatever brand you use) the screws on the backplate before you tighten them.....and get it ready for the new motor.

Ha ha. The pump cost me $250 roughly a couple of years back. I'm going to get the inner gear crack tested and reassemble.

I built my eng near the end of last year with forged bits http://www.skylinesaustralia.com/forums/En...&hl=rebuild but, I don't mind pulling it apart to do a few other little things...like fit this pump, sump baffle, sump extension, extra sump vent line, replace and gap top rings to factory specs etc.

      WTB R34 GTR Guard Liners

      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

      You have a knack for photography my friend. It makes the 86 look like a complete bucket. The 34 went with you to Europe and back. It's special. (we all feel the same about our 'shitboxes' that every bystander seems to absolutely love)
