N1 Oil Pump - Epic Fail

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.

Could the design be re jigged to take the Reimax oversized gears?

Yes, very easily.

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?

[N1GTR]

Well, like anything its a matter of throwing enough money at it

......and knowing you wont be stuck with a heap of something that no one wants burning a hole in the pocket

If you want to pay for the tooling I can do it here

Do you work for a machinest

I teach cad for a job

You want a pump

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.

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

Mmm...a 90mm bore block would be nice in a tall deck version.

Group buy anyone?

[r33_racer]

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.

[proengines]

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.

[bigmikespec]

I read somewhere that Dart were boycotting (or getting people to boycott) the Chinese copy blocks and buy original Dart stuff.
