The ones I thought you were alluding too?

Oh right, well i had one all designed up ready to be made over 12months ago, it's still on the to-do list, and seeing as i dont have a suitable car/engine to put it on i can't do any testing. Add to that it'd cost close to 2k with the spline drive gears.

However if there were people interested then i'd look at getting it produced.

Has any one considered the fact that some one has sent an N1 pump to china and got them copied and thats what you are buying

I have a friend with a workshop that specialises in Nissan and he was telling me whats been done

Also consider the fact that all of a sudden N1 blocks are showing up all over the place as well

He was telling me that these are chinese copies as well

yes ive heard about the copied blocks...didn't consider the N1 pumps though. Now that i have a product i know i can rely on i will never buy another N1 pump.

Yeah makes you think doesnt it

In reality pumps are more likey to be copied than blocks

Much easier to produce

I've got absolutely no issue with n1 blocks being manufactured in china, in fact I would very much welcome it.

nissan has not been casting n1 blocks for at least 5 years and globally all old stock has pretty much disappeared.

If Nissan is going not going to supply new blocks where will we get them from? Good luck to anyone that has gone to the effort of casting them, I'll take 5.

Id go to the extra expense of properly balancing the engine and running an ATI balancer than forking out $2500 on an N1. Im yet to crack an 05U thats been properly built.

But everone has different ideas i suppose.

Ive looked into getting blocks cast, havnt given up on it, but not looking at N1 (24U) blocks, going RRR blocks instead.

The production cost isnt cheap, but luckily i know a place that owe me a huge favour.

What about aluminium alloy blocks with steel sleeves? :whistling:

Cast or billet? For billet it costs between 10-15k for the 1st and 8-10k there after, depending if you want it to have the factory shape on the outside or not.

Do you work for a machinest

I teach cad for a job

You want a pump

We have a large machine shop here (a small section of it actually used to be an engine reconditioning shop)

Im an engineer at an (ductile) iron foundry. I do the majority of product design, tooling, process improvement etc. so CAD/CAM is no problem

Its not cost effective to have one of our cnc's tied up doing tooling so we usually outsource that component (still trying to get my own)

Limited to 12-13tonne max. per pour

Aftermarket blocks would be awesome!

But as shane said, Billet...super exxy!

A chinese casted iron block would be great...so long as its decent quality...no doubt would come out cheaper then something from here. I guess ideally, a casted block in china then final machining here in Oz.

Chinese cast iron blocks are not a nice thing from those I've seen, the same with cylinder heads. There are copies of the Dart Chev blocks coming from China now and they look good but the hardness just isn't there and the geometry apparently isn't great. There's a long thread about them on speedtalk at the moment.

Some stuff from China is really good, including many of the cheaper US branded conrods but a block is a lot more complex item. There are even fake ARP bolts being made there, it's good to know that the Spool rods run genuine ARP bolts, they arrive in the ARP packet separate to the rods. Some other rods around have bolts that look a little suss, they have ARP stamped on the head but not the finish you would expect on the rest of the bolt or no brand at all.

    • 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.
