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).

      Stagea Front CV Axle Question

      Man, different parts but the same numbers is terrible @dbm7! And it doesn't help that most online shops don't list the part numbers at all. They just give a list of compatible models...

      Slow when hot could also be because its getting more dynamic compression, OR things are getting a bit tighter once it is all expanded. If it were an earthing issue, typically I'd expect you to have it have issues all the time. Unless it's really a combination of both things. Where the higher compression, and things being a bit tighter, is giving that bit of extra load and you do need a slight clean up on the cables/connections.

      Stagea Front CV Axle Question

      By dbm7 · Posted

      Yeah, this is one of the most annoying things about nissan part numbers... I've got an unrelated example... Image is of the AT output shaft ~ they have the same part#, but clearly the shaft on the left is beefier design to that on the right ...the difference (essentially) is the 'lighter' shaft on the right, is for engines up to RB25DE (this includes RB20 variants) : the shaft on the left is for RB25/26DET(T)....are they interchangeable? Yes...but obviously one shaft is going to be stronger than the other...and, the lighter shaft is around USD115, but the heavier shaft closer to USD150...same part#... ...epc-data usually tells a tale ~ the amayama listing for 39100-23U60 has a note "Longest side is between 60 and 105 cm" ; no such info is there for 39100-23U70 ...and given the great disparity in price between the 2 parts, it makes me at least curious (to the point of caution) where the 'extra money' went? ...ie; these 2 parts have a cost difference that (to myself at least) isn't explained by 'plastic boot'...ie; with amayama there's AUD700 price difference ...plastic versus rubber?...I'm not seeing it like that...and 60cm ~ 105cm...??...that's a huge disparity....something hinky going on here... I'd try searching by VIN, not model... /2cents

      I don't know for sure, but I'd expect them all to be interchangeable given the diff end and hub end don't move/change between any C34 series. Often Nissan will change part numbers and the aftermarket follows those year ranges; but the original part number change doesn't mean other parts won't fit. The change could be a change in material, internal parts or even just supplier. For example, all the RB gearbox to engine bolts are no longer available and there is a new part number instead. The only change is they went from cadmium plated bolts to zinc plated due to the issues manufacturing with Cadmium. They look different but work the same.

      One year is a bit concerning. Did you try contacting GSP? It says 5 year warranty on the box if I remember correctly. I'm also running their driveshafts on my S2 Stagea.   You could check the part numbers on Amayama for your year. Here's the link for my 1998 which gives the 39100-23U60 part number. Well, that and 39100-23U70. https://www.amayama.com/en/genuine-catalogs/epc/nissan-japan/stagea/wgnc34/6649-rb25det/trans/391 What does it say for yours?
