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.

Had them a few months, revs to 8000rpm.

Nice

+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.

    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
    • ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
