I havent been on here much lately to see this thread.

Just caught wind of this. Have not heard anything about these failed pumps (which I normally would being an Aussie manufacturer) and if this is so I would be keen to hear about it. Can you enlighten me?

. In saying that we have only have two broken pumps out of the many 100's of units that we have sold internationally. Both these pumps had failed inner gears but were both due to the same reason which was from the pumps being installed onto used later model RB26 cranks that had the leading edge of the drive flats rounded which in turn enable the crank to try and turn within the inner gear. Obviously no matter how strong you manufacture a gear it is still a mechanical part that can fail given the correct environment to do so[/size]]

Yes, those highlighted points are taking it a little out of context to the full information, but it is still a failure.

Where did this come from? You should check your sent emails for that exact quote Andrew, because It came from your email.

I am leaning more towards a HKS oil pump mainly because according to HKS Australia they are the ONLY oil pump that is 100% made in Japan...

Hi Chris,

I'm glad you have an engine builder and are not one yourself. It seems that you don't quite understand basic mechanical properties which is fine but maybe next time you might think a bit further before posting up your ill informed wisdom.

Let me run through it - When you have a loaded gear that effectively driven inside by something that is larger than it (current twin flat RB inner gear design) then no matter how strong the gear is, it is still prone to failure if the drive is allowed to become a larger diameter than the ID hole in the gear. It does not matter if the gear is made from unobtainium and treated in kryptonite, it is still physically impossible for the gear to withstand the pressures being placed on it. It WILL still fail when the 2 materials are of similar nature in composition. IE: solid metal drive inside metal gear.

The "documented failures" you refer were not because of the product quality, they were a result of incorrect installation. Just the same as you can't blame a failed piston that has seen too much pre ignition on the manufacturer when it was the tuners issue that he could not tune properly (or other factors that are out of the piston manufactures scope that could cause the issue). A failure is not just a failure as you so professionally put it.

Nitto goes to a lot more expense than other manufactures to make these gears as strong as possible in both materials and processes used. This is fact. Have you tried emailing or calling HKS, Reimax, JUN, Greddy etc about their pumps asking where they are made, how they are made and about their failures? I would guess not and would also guess that you would not even get a reply. I'm not talking about a middleman wholesaler either that will tell you what you want to hear.

It is unfortunate that manufactures face this kind of flawed information being plastered over forums these days especially when it is information that has been directly supplied and obviously misunderstood by those that have recieved it due to not really understanding what they are reading. This is why you do not see many manufactures being actively involved in forums. Too many users trying to big note themselves to the wider community as gurus when their profession is something totally unrelated and their knowledge of what they are talking about is not up to scratch. It is a real shame. This by the way does not reflect the majority of forum users.

I reiterate once again - Nitto has not had any feedback on damaged gears in any way due to the product quality. ONLY due to ill fitment which was accepted by the installers in question. The "documented failuers" were documented by us and were not due to our product. Get it right next time before you suggest toward an issue being present that is not.

I reiterate my own point

Yes, those highlighted points are taking it a little out of context to the full information, but it is still a failure.

I am aware of the mechanical issue with the collar not mating to the oil pump drive correctly.

I didnt blame NITTO directly for the failure, I mentioned that there had been TWO failures in relation to the pumps.

Yes, your information is from you directly, Why do you think I emailed you about the oil pumps you have in testing currently that use a different style of pump drive.

What issue did I mention was present? NONE, I brought up the fact, that you YOURSELF had told me of these 2 known failures, which is also good that a manufacturer can speak of them openly.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated. Rb25det s1 walbro255 fuel pump nismo fpr holset hx35 turbo fmic 3" exhaust freddy intake manifold q45tb q45 maf   Re: s1 RB25det flooding at start up Fri Apr 12, 2013 5:07 am No, I didn't. I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      By GTSBoy · Posted

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.
