well....why did the pump you see die? I am yet to be convinced there is some basic issue with n1 oil pumps.

they get used in lots (most?) builds?

those motors get treated very hard (otherwise why did the owner spend 5-15K to build it?)

anything goes wrong in the bottom end...first place a bit goes to is the tight clearance oil pump. put any shit through it and it breaks.

once the pump breakes due to the other problem the whole motor dies very soon after.

first thing you find when you pull a motor apart is a broken oil pump.

bottom line is....finding the *real* reason a motor dies is very very complex. oil pumps do not often die on their own but they are very often the first symptom of the real problem

It's usually always the same story......

No aftermarket harmonic balancer and/or rev limiter pump shock. This pump died from both at launch......broken inner gear.

as long as you dont smash the limiter you will be fine

heres one with gears broken

http://www.gtr.co.uk/forum/104505-n1-oil-pump-tomei.html

have a look around on the site you'll find more, and race pace had a couple break gears due to limiter bashing

i only got the tomei one cause im paranoid and a dry sump setup for me is over kill

just read that thread in the uk, it had only done 625km and looks like it had other issues that caused the failure.

been limiter bashing(7500) mine for three years now, hope it holds out for another three.

that....or you could give them a call and ask? 02 9648 4264

JD74 - as per duncans post & my original suggestion a lot earlier in the piece...pick up the phone & call the above number.

reason not many people know about this pump is because it is tried & proven, simple as that.

who cares if it was even made in india or vietnam at the end of the day, it is a great pump :)

if it can chew through bits of cast block that should compel you right?

My N1 pump has eaten something (scoring on the gears, probably left over thrust washer ;)) and not broken. Not happy with the wear on the drive face though. Personally I think it's a clearance issue as to why they break, aswell as others. If you look through that linked thread you'll find that the guy that broke the Jun pump was also using a beat up stock balancer.. poor drive clearances and shitty balancer = broken pump? seems like we're going over the same ground again..

JD74 - why dont you do the smart thing?

ring/email CRD and fken ask rather than harp on like a child?

Well, because up untill now NO ONE seemed to even know where they came from......even after I asked a few times.

Harp on like a child ? gimme a break.

I saw user CRD reading this thread and STILL not jumping in. What gives ?

Is CRD really NITTO ? Are NITTO parts really 'Jun Jobber Parts' that are resold under the NITTO brand ? .....sure looks that way to me.

HHmm....people are 'sourcing pumps through CRD'.....

I still can't get a straight answer and what's even more funny, the people that purchased these pumps don't even know for sure.

People are quick to jump to their...ehem...'THEIR' defence, when in reality......noone even knows who THEY are.

Thanks for the info......and thanks for calling me a child.

And the Google comment ? IT'S THE 21ST CENTURY. IF YOU CAN NOT BE FOUND ON GOOGLE, THERE IS SOMETHING WRONG.

I'm done.

Hey mate I feel your pain! Sometimes it can be like getting blood out of a stone...

FWIW

According to Godzilla Motorsport Nitto (Nitto Performance Engineering) is Croydon Racing Developments (CRD) own brand

found that with GOOGLE :D

Thanks man....... Your Google-Fu is stronger than mine ;)

I'm buying a Reimax anyways.....because it takes more than an upgraded Gear and a Jun Pump Housing to get my money.

  • 2 weeks later...

Ive just spent a few hours reading every bit of this post and it was extremly informative

Problem was I was chasing info and opinions on the Reimax complete oil pump (not just the gears) and as soon as someone mentioned it ....... no more posts, what a crack up, I pissed myself laughing

Anyway what do people think? http://www.reimax.co.jp/pages/products/lower-area/index.html

The company certinly has the credentials

i see your Reimax and raise you a newly released Nitto pump with billet rear cover for added strength.

billet rear cover u say paul, so a full billet housing must be pretty good then huh? :)

    • Hi. This is just my curiosity because iam sure the tuner figure something out...but either way i want to ask. The "problem" is that the Nistune ECU (Stagea FW and RB25DET NEO from Stagea) sees many times the speed than the speedo does(he says the speedo show 120 km/h - correct speed and the ECU shows like 510km/h ) I told him that this car/tranny getting speed from rear diff. If iam not mistaken the RB25DET NEO "need" to see tranny speed sensor? (my tranny has the plug for it). So couple of "question" If he connects/wire the speed sensor to the tranny...are the signals gonna intervene and if...what if he disconnects the rear diff one and the speedo stops working? Or the "new" sensor from the tranny "take over" and will not going need the one from diff? As i said i know he figure/get that done...iam just curious to know what are the solutions 🙂 
    • Your IACV is set to idle too low. You need to adjust it via the screw Duncan mentioned. From memory it should be 650rpm with the valve electrics unplugged. What is it trying to idle at with the IACV plugged in?
    • Ahhh, I need the whole head unit. I definitely needed to roll back through and review your setup, ha ha! Neat setup they have going on. I just need a full double din head unit. But I want good and responsive. I might have to review what the likes of pioneer have out these days.
    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is may e 1 wire in the ecu plug I need to move to rectify this. Dose anyone here have any ideas?   Cheers guys
    • Sorry I haven't been following all the detail, so you may have tried this. Does it idle with the tiniest bit of throttle you can add? You've mentioned the IACV, does it have an AAC valve and have you adjusted it at all (ie, screw the idle adjust screw all the way in, then back it out a couple of turns until idle is stable)?
