Thats good mate!

Lol, sounds like you need more free time to do personal stuff! Work is always a pain in the arse!

[r33_racer]

Edited.

[FineLine]

Another myth shot down. That pump is junk mike.

Return to sender.

[r33_racer]

Mate, you are not wrong!

[Rolls]

Imagine what those flakes would have done to your engine!

[tweety bird]

i think i will skip the nitto pump and go for a tomei pump.

[XRATED]

WOW! Not cool man...

Back to jap pumps I guess.

[r33_racer]

It was very shocking! I was not expecting that at all.

[Beer Baron]

I don't even have to ask what pump it was. what a shame. yeah tomei or reimax. every single one I've opened was beautifully finished. it's not like the pump you had was a cheapie either right? from memory they are about the same price as a jun pump.

[Beer Baron]

oh. forgot to add. awesome project mate. great work on the v-bands. everyone I know complaining about leaking v-bands has the shit ones that are universal (no male/female). interestingly the ones that come with HKS gear have the proper lip and a female side to go with it, so do all the V-bands on my 94mm (3.75inch) trust power evolution exhaust. the other ones are just crap.

[dori34]

is this the first case ever of poor quality on a Nitto pump?

seems like the first ive heard of it

How many have you opened up to look inside?

Thanks mate. You are dead right about the v bands. There are vbands and then there are vbands made properly. Not many seem to make them properly. But its good to see the Japs do them right with their exhaust systems.

Yeh well I need the most oil flow I can get with the pump and from what figures I could find the Reimax has the highest. So thats my reasoning behind that choice. Though I will be pulling that one apart and inspecting it also as my paranoia has only grown now. You just cant be too careful.

I could be the only one that had that problem with that pump. No doubt there are alot of people running them with alot of success, so there is no real reason to think they are all like that. There will always be some human error with anything assembled by one; missed a problem, didnt clean it properly or whatever. Which I understand perfectly well as we all make mistakes from time to time. My annoyance comes from the fact that it is an oil pump and it is really the most important part of an engine and there really is no margin for error with something so vital otherwise there is the potential for engine failure. In most cases when people are fitting these pumps to engines, they are expensive builds otherwise they wouldnt be using one.

Anyway im not bagging them out or anything like that. Mistakes happen. All I want to preach to everyone here is make sure you check everything yourself if you are in a position to do so, not just an oil pump but with everything. Engines are too important to make mistakes with.

r33_racer(Michael) - First of all I must say that we are surprised to see the picturesthat have been posted above and apologise that you have had this negativeexperience with our product.

This is the firsttime we have ever had this feedback since we started selling this product withhundreds of units sold worldwide in its current design format.

As an Australian companydoing our upmost to service the performance industry both here in Australia andinternationally, I do wish you had made the time to take advantage of our localposition in the market and contacted us directly about the problem you haveencountered before closing the book.

We prideourselves in backing up our product 100% with professionalism and first classaftersales service. This service is certainly not something that is readilyavailable with most other brands be it Japanese, American or whatever.

For future referenceit is not just “spruke”, we do manufacture the oil pump gears and backingplates here in Australia and cast our housings in Taiwan to keep the cost down.Australian casting would unfortunately price the pump way out of the ball park.The pump is measured and assembled here in Australia by our staff and we are thereforesomewhat perplexed that you have a defective Nitto pump housing.

We only found outabout your pump this morning and are eagerly awaiting its return on Monday sothe unit can be identified, the issue investigated and to assess any qualitycontrol concerns. This is something that we take very seriously and definitelynot with a grain of salt.

I would be morethan happy to go into detail regarding the huge effort that is required tocontinually manufacture gear sets for these pumps to the same exacting levelsof quality for those interested.

For any SAUmembers that may be reading this we encourage any kind of direct feedback fromthe public whether they use our product or not. Interaction with theperformance community is something that benefits everyone and we are alwaysmore than happy to discuss any ideas or issues.

We apologiseagain for your negative experience Michael and are awaiting the components fromthe Dealer to determine the exact issue and identify your problem.

Regards

I appreciate the response Andrew. Im an easy going guy and very understanding, especially when it comes to engineering and manufacturing as I work in that industry myself . I dont get annoyed/pissed off very often or easily for that matter, but unfortunately this occurence was enough to really tick me off past my usual threshold as the fault had the potential to do serious harm and thats what led to the rash decision to get another pump and bring the issue to light in my build thread here. I admit I could have handled this more professionally and contacted you directly first, but I was not in the clearest mind set that night or following day.

As I said above Im not here to run your product into the ground, it appears to be, for the most part a good pump as alot of people are running them without issue. I simply wanted to inform people of what could have happened if you dont take the time to be pedantic with everything during a build as it is possible for people to make mistakes. There is a factor of human error in everything. But as I've said above, its the oil pump or heart of the engine, if it has a problem, your whole engine has a problem. It has to be 100%. Had I not inspected the pump and put it on as your instructions stated is acceptable there is a chance my motor could have died and I dont like taking chances.

Anyway once again I appreciate you taking the time to find my thread and make an appearance and statement regarding the matter. My own apologies to you for any immature and silly comments I made previously whilst in my hot headed state.

Thanks mate. You are dead right about the v bands. There are vbands and then there are vbands made properly. Not many seem to make them properly. But its good to see the Japs do them right with their exhaust systems.

well to be fair even the japs only do them properly about half the time. i've also seen some jap brand exhausts with v-band that were the usual crappy type.

I see. Well thats a little dissappointing to hear. I just cant comprehend how some people can think two flat rings butting against eachother can be expected to seal properly when all they have is the clamp to align and compress them. Half the time when they get welded onto the exhaust tube they distort a little anyway which doesnt make its task any easier.

You really need the male lip and female seat to align them and seal up similiar to a slip-joint, nice snug fit at room temp, soon as it gets to operating temp expansion creates a nice mechanical lock and seal.

[XRATED]

At least they're activly looking for problem parts and are more than willing to look into the problems... And Mike... in all honsety, you displayed your dissapointment better than most. I don't think you even 'named' the brand in your rant.

Hopefully Nitto up the ante and fix the problems.. AND move into some more innovative solutions for rb oil pumps and drives...

Spline drives anyone???

[r33_racer]

I spoke to Andrew today about it all. He is a top bloke. We covered it all and I think things are sorted between us.

As far as im aware from what we spoke about today they are currently working on the spline drive. From what he said they are in the fine tuning stages to get it spot on, playing around with variations of splines and clearances. Once they get it done it should be a good thing!

No pics at the moment, but my brother ceramic coated the valves and combustion chambers on my head. I lapped the valves in again since I ported it as the machineshop tried a new 5 angle job on the inlet and it made some good gains over the standard 3 angle. I would have to check the flow figures, but from memory I think it picked up around 10CFM. Was pretty good. But I need to get a standard head flowed so I can compare it to my ported head! See if I made any gains. However, I now have to get the head cleaned properly before I can assemble it. There is sand blasting grit all through it!

[XRATED]

Sounds promising....

Are you going to run one of they're pumps still?
