Ive been looking at up grading my oil pump from stock and always wondered about these billet pump gears

http://www.kec.com.au/index.php?option=com...&Itemid=327

they are around the $600 mark, has anyone used them, at what point would you consider the need to upgrade. would 350rwkw @ 8000 rpm in any RB engine

be safe with standard pump and shimed spring?

I came across these KEC gears not long ago but I had never heard of them (the gears, I know who KEC are) and am quite dubious.. I am more inclined to go with the JPC gears as JPC are reknowned for building tough RB30's whereas Kostecki's are reknowned for their big v8 work and ripping customers off (re: IM240 testing).

A friend of mine has the JPC gears on his 700hp 25/30. No dramas as yet.

That's very good to hear :laugh: got any more specs or details? how long has he had them? what does he rev the thing to?

Cheers!

The same engine had a N1 on there. Pulled is down due to a bearing failure and found to nice cracks in the gear.

The JPC ones are an upgrade but you can compare to the NITTO pumps.

You get what you pay for.

I thought the JPC gears were only for N1 oil pumps and not the standard ones?

p.s How would you remove the back plating of the oil pump when it has locktite on it?

impact screw driver or allen in the SR20 case.

We run new rotors in all our oil pumps (sr's) as thety are $80 from nissan.

As for rb26 i would track down whoever is making these as i cant image many places tooling up for it. Is TufRX3 (karl) doing them?

i cant see the point in buying billet gears... i would just buy a decent pump.

+1 for the impact screwdriver

I've already got an N1 pump and while there are no cracks, I can visually see wear on the drive surface and that worries me. I'm also not in a position to shell out another 1.5-2k for a new oil pump so if I can get some stronger gears for my N1 pump, then awesome. :)

I can see the point when i dont have a money tree, Hmmm $350 for gears that wont fail like stock ones,

or risk leaving stock ones in there. Easy choice for me when im on a budget.

depends, if the pump housing has to much rotor float you are up for a new housing and this gear set..... which is the same as wholesale on something decent. If you have a few housings that are in spec then yeah it makes sense.

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

      By GoHashiriya · Posted

      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
