I disagree totally. Do you think JUN havent thought of this already? old Mr tanaka didn't get to where he is now by being secretive and paranoid... obviously when you sell a product, the R&D that has gone into it is now out in the public domain, and is free to be copied... Lots of other people have these plenums too, and even if some chinese guy does copy it, he doesnt know what the engineer was thinking when he designed it, so the copied product will never, ever be as good as the original.

It reminds me of Mario when he first started out 4-5 years ago with GTR700 - he wouldnt show photos of the fancy cooling system that everyone now knows about. it still doesnt mean that people know how it works, or how to do the mod properly.

just my 2c..

Cheers,

Matt

The reason is if i show you whats inside and someone copies it it would be worth a lot less than i paid for it.Also if JUN has done all the testing would it be fair for some chinese guy to copy it?

I would think that's not really the "spirit" of the forum. I'm sure anyone that want's to make money from copying the design would not rely on low res photos from this forum and would just buy one from Japan.

Along your line of reasoning, I paid a lot more a couple of years ago for my '93 GTR than people paid up until recently for 15 yo imports. I also paid a lot more for my genuine HKS terb manifolds than people pay for local or Chinese copies. But that's my choice.

Out of interest, I'm also using a single throttle conversion myself and am happy for anyone to look at the details of the plates and the custom throttle body. A hotly debated topic but personally I think it's an advantage for a high revving, standard 2.6L with high lift cams. I would imagine a single throttle body also helps with a map sensor type ECU setup. But again, my choice.

I don't think that's really true. even if it was, you didn't buy it for an investment. it's only worth to you is in the performance gain it can give you and this 'value/worth' won't be diminished at all by someone else seeing it (even if they did copy it). ie. you didn't buy it for it's $ value. you could argue that your performance advantage over someone else could be reduced if they saw it, but that's not true as it's not a one-off that only you know how to make, anyone can buy one.

anyway, it's up to you whether or not you want to show people. it certainly looks good from the outside. enjoy.

Thanks guys.

as for R31Nismoid what is it that you want?

I'll give a complete list of mods and at least 4 dyno sheets with all runs over 290AWKW.

Also GAV what sort of mods have you done on your car. and did you notice an improvement with the new plenum down low or was it all up top.

Cheers.

i'm not sure on an exact price as we are always getting multiple things done at a time.

As for a better price give CRD a call.

one little bad thing is that they take about 3 months to get once they are ordered, as they only make them once the money is in.

power we have no real idea as no one with a set up like ours has done it before.

I'll post up a dyno sheet with the new figures once its all installed.

All up top - but the engine was/is set up for high revs anyway (high lift cams, extensive porting, big low mounts).

      A 1.5 way is a 2 way. It is just a 2 way with a less aggressive ramp on overrun.

      The ABS and/or TCS being missing/broken will not cause the engine to misbehave. It just casues CEL to come on and annoy you. The CEL is useless if it is always on, so you have to do the things you have to do to get rid of it, so it can be useful. Being a Stag ECU, then yes, it will not expect TCS to be present. But it will expect ABS to be present and working. You will need to either make the ABS CU talk to the ECU (don't ask me what that will take on an NA R34), and make sure the hardware is working....or, you just need to blank it out in Nistune. Do not persist with the stock ECU. You will just have problems. Gte it Nistuned. Start from there. DO YOU HAVE A BOOST SENSOR? The ECU's boost sensor that it. It is connected to the loom at the rear of the coil cover. Usually rides on the firewall on an R34, but is usually bolted down to a bracket along with all the other crap at the back of the coil cover when a Neo is dropped into another car. If you do not have it, the ECU will shit the bed. So, do you have one?

      So sadly the fuel pump etc was not it. The pump and filter is new and it is still cutting around 4000 rpm. A read something about ABS/TCS (engine is from stagea and ECU too so no TCS) and i dont know for 100% that my car has ABS. It has ABS "cube" in engine bay but i dont think it works(or at least from my braking experience). Can be something like that?  I will be driving the car next week to Nistune tuner to properly see what is wrong...

      the Tomei LSD fluid with lsd kit. frustrated that it was shaking the car to crap and affecting everything else negatively, I pulled the diff last night, and removed the lsd carrier, could not find anything wrong, however it seem to be 100 locked up acceleration, and deacceleration, wondering if they sent me a 2 way not a 1.5??  either way I installed the stock open carrier back in place. test drove everything smooth as butter again. no shake, shutter, random, what felt like clutch slip and grab or drive shaft play, etc. something differently wrong in side the lsd. I might bother taking it apart (if possible) to figure out what's going on inside this carrier, as bought too long ago to return.  only draw back is its back to a one wheel wonder.
