i ordered a brand new n1 block today actually its in melbourne and gonna be here in 4 days or so hopefully :( not sure if there are any others left or not.

not cheap but when u want big power u gotta pay.

i dont think putting $50k into a china safe is a smart idea so im doing a n1 block to replace the 05U block :( buy the best safe then start putting money in it is a much smarter idea.

my 05U cracked after 1200km of use with the new setup. not happy at all, but this means the new block wont limit power output for a long while yet.

No - just the same tuner

do u even know where it was tuned at ? im using the autronics by the way so u can guess who it wasnt :wave:

i got the djetro sitting aside and if i use that ill use who u are talking about but i am keeping autronics at the moment and ive found a good tuner so i dont need to sell it.

why bring workshops into it anyway?

Chill man - only having a stir. :D

The crack is in a known weak place (as you say) and actually is more a function of the balancing and revs that the engine sees. In my case it was caused by poor harmonics and high revs. Was certainly a deciding factor in me spending the $$$ on a full counter weighted crank, ATI damper and close attention to balancing.

no worries gav i am just over all the workshop battles and so forth in perth its annoying as no one agrees on who is good and bad, etc its a losing battle i just keep my mouth shut now :wave:

HI Gav, this comment sparked my interest. The block cracking I have seen has been vertically, up the water jacket. I haven’t seen one go along the block. Which way did yours crack?

:blink: cheers :P

for us visually challanged people can someone point out the crack on that pic?

under the central bottom right hand bolt.... EDIT: Guess not. one day... I still want my questions below answered... please...

I think...

and because I really don't know, couldn't it be fixed? unfixable? weaker (how much)? and could bracing help prevent it happening?

It was a while ago and I don't have a very good piccy, but I think it was at the top of the rib in the red circle.

Hard block that hole, and that particular water jacket, run and external high pressure feed straight from your oil pump and you will go along way to solving the problem of cracked blocks!!!

The rusty water runs down the block due to gravity. So look for the highest point of leaking water, you can see the hairline crack going front to rear.

:( cheers :D

Last year you could pick them up no problems. You cant do that anymore as production has stopped in Japan and there are none left in Australia, and very rare and expensive in Japan now.

I have just found out about this.

I can still buy N1 blocks out of Japan and they are still being made.

You can still get the Nur block aswell which you can tell because of the x in the right corner after the engine number.

And also the GT block is still being made and has a 4 month waiting list :

Which is 5mm taller then an N1 block and 3mm thicker walls than the N1 block.

Bring a bunch into Australiua then as I know quite alot of people who are after them.

For the past 2 months it has been virtually impossible to get hold of one. Everyone promises the world yet cant deliver.

I think you have been misinfomred.

N1 blocks are still unavailable in Japan. If you can get them...I will have ten please.

Also, the GT block is not 'taller' than the N1 block. How do I know? I've had 2 sitting beside each other. Interesting that you say there is a waiting list for the GT block. Maybe if they get another lot of 300, they will make another run.

    • First up, I wouldn't use PID straight up for boost control. There's also other control techniques that can be implemented. And as I said, and you keep missing the point. It's not the ONE thing, it's the wrapping it up together with everything else in the one system that starts to unravel the problem. It's why there are people who can work in a certain field as a generalist, IE a IT person, and then there are specialists. IE, an SQL database specialist. Sure the IT person can build and run a database, and it'll work, however theyll likely never be as good as a specialist.   So, as said, it's not as simple as you're thinking. And yes, there's a limit to the number of everything's in MCUs, and they run out far to freaking fast when you're designing a complex system, which means you have to make compromises. Add to that, you'll have a limited team working on it, so fixing / tweaking some features means some features are a higher priority than others. Add to that, someone might fix a problem around a certain unrelated feature, and that change due to other complexities in the system design, can now cause a new, unforseen bug in something else.   The whole thing is, as said, sometimes split systems can work as good, and if not better. Plus when there's no need to spend $4k on an all in one solution, to meet the needs of a $200 system, maybe don't just spout off things others have said / you've read. There's a lot of misinformation on the internet, including in translated service manuals, and data sheets. Going and doing, so that you know, is better than stating something you read. Stating something that has been read, is about as useful as an engineering graduate, as all they know is what they've read. And trust me, nearly every engineering graduate is useless in the real world. And add to that, if you don't know this stuff, and just have an opinion, maybe accept what people with experience are telling you as information, and don't keep reciting the exact same thing over and over in response.
    • How complicated is PID boost control? To me it really doesn't seem that difficult. I'm not disputing the core assertion (specialization can be better than general purpose solutions), I'm just saying we're 30+ years removed from the days when transistor budgets were in the thousands and we had to hem and haw about whether there's enough ECC DRAM or enough clock cycles or the interrupt handler can respond fast enough to handle another task. I really struggle to see how a Greddy Profec or an HKS EVC7 or whatever else is somehow a far superior solution to what you get in a Haltech Nexus/Elite ECU. I don't see OEMs spending time on dedicated boost control modules in any car I've ever touched. Is there value to separating out a motor controller or engine controller vs an infotainment module? Of course, those are two completely different tasks with highly divergent requirements. The reason why I cite data sheets, service manuals, etc is because as you have clearly suggested I don't know what I'm doing, can't learn how to do anything correctly, and have never actually done anything myself. So when I do offer advice to people I like to use sources that are not just based off of taking my word for it and can be independently verified by others so it's not just my misinterpretation of a primary source.
    • That's awesome, well done! Love all these older Datsun / Nissans so rare now
    • As I said, there's trade offs to jamming EVERYTHING in. Timing, resources etc, being the huge ones. Calling out the factory ECU has nothing to do with it, as it doesn't do any form of fancy boost control. It's all open loop boost control. You mention the Haltech Nexus, that's effectively two separate devices jammed into one box. What you quote about it, is proof for that. So now you've lost flexibility as a product too...   A product designed to do one thing really well, will always beat other products doing multiple things. Also, I wouldn't knock COTS stuff, you'd be surprised how many things are using it, that you're probably totally in love with As for the SpaceX comment that we're working directly with them, it's about the type of stuff we're doing. We're doing design work, and breaking world firsts. If you can't understand that I have real world hands on experience, including in very modern tech, and actually understand this stuff, then to avoid useless debates where you just won't accept fact and experience, from here on, it seems you'd be be happy I (and possibly anyone with knowledge really) not reply to your questions, or input, no matter how much help you could be given to help you, or let you learn. It seems you're happy reading your data sheets, factory service manuals, and only want people to reinforce your thoughts and points of view. 
    • I don't really understand because clearly it's possible. The factory ECU is running on like a 4 MHz 16-bit processor. Modern GDI ECUs have like 200 MHz superscalar cores with floating point units too. The Haltech Nexus has two 240 MHz CPU cores. The Elite 2500 is a single 80 MHz core. Surely 20x the compute means adding some PID boost control logic isn't that complicated. I'm not saying clock speed is everything, but the requirements to add boost control to a port injection 6 cylinder ECU are really not that difficult. More I/O, more interrupt handlers, more working memory, etc isn't that crazy to figure out. SpaceX if anything shows just how far you can get arguably doing things the "wrong" way, ie x86 COTS running C++ on Linux. That is about as far away from the "correct" architecture as it gets for a real time system, but it works anyways.
