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).

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..

      Lower A arm Skyline v35

      By sonicii · Posted

      The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.

      Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????

      Thanks Paul I reached out to Autotainment but they no longer work on JDM cars as the guy who used to do the work moved on and is no longer doing that kind of work. I am talking with Level Up Audio though.
