Hey all,

I am currently in the process of building an RB30DET Neo and was planning to re-use my oil pump as it is an N1 type...

However, upon removal, the drive gear face looks like it's been slapping against the crank on the edge so looks like I'll need some billet gears. (previous owner must have like the limiter...)

Housing does look ok, but there are 2 wear marks? that I can feel.

Do yas reckon the housing is still usable? I am trying to avoid buying a new N1 type oil pump as I've read they are not of the same quality...

Cheers!

Daniel

Get a new housing, I made the mistake of using an old housing with billet gears and this was the result.

Must have been a mixture of free play and version 1 of the Spool gears. I'm on the second version with a brand new N1 housing and it's been good since.

hey guys, thanks for the advice! appreciate it :)

Wow Johnny, those gears are completely cooked ?

GTSBoy, yes that is true, my initial thoughts were to either put a new N1 pump or re-use the original housing if viable just not to double up on costs. My next question I guess would be, were those claims of "not good" ever really verified or just a he said/she said scenario?

If I was to build a motor again (hope I never do it again) then straight up Nitto oil pump with their collar.

A poor man, pays twice. I've bought 2x sets of Spool gears, 1x brand new N1 oil pump.

All that equals a new Nitto oil pump with change left over.

GTSBoy, yes that is a fair point too. I guess it is hard to verify on public forums lol.

Too true Johnny, I did fathom the Nitto pump as they are amazing and have very good reputation but the $$$, and totally agree the poor man pays twice, ouch!

Thanks for the advice and conversation gents! Now off to ponder the decision to make...

Ah good old RB life.

      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
