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).

      My BMW 335i

      Noted. Have noticed BMW are more 'high maintenance' for sure. They've attracted my attention as I think the used car prices seem reasonable vs other options, and the extra quality overall vs a commodore / camry / corolla or similar of the same vintage is appealing, especially the interior, and they are more on the sporty side whereas the others mentioned can be more cruising or economical A-to-B only.

      Haha yeah I know, this is SAU after all, why are we talking about BMW's of all things!? I hear you on the 'don't have to worry about it' side of things. Having been fortunate enough to be have been able to buy a brand new motorbike or two...never really enjoyed them as much as I'd have liked as you worry so much about where you park it, will it get scratched, stolen, attempted theft, knocked over, etc...and yes dirty. Older less valuable bikes you can just go where you want and park it wherever and not really worry that much in comparison. And who cares if it gets dirty! Never owned a V8, and have had my eyes on VE / VF commodores for years but with their prices climbing so high, the M3 has come into focus more as prices are much closer than I've ever seen...is it a potential contender now?...of course need to factor in the S65 'maintenance' especially and like you said general M car 'tax'. One can dream anyway. But more on the reality front - did read the whole 330i thread as well and was a great read too, both threads enlightening as I've never even driven one of these cars! I do recall 330i didn't seem to have the same amount of issues for almost the same car (turbos and related differences notwithstanding)...perhaps down to getting it earlier in it's life so looked after better than the 335i? Perhaps so as your 130i has been good and quite similar, so finding a car that's been looked after well is the especially-crucial-BMW-first-step.

      Nice. Dont worry about the time of not running. My current skyline hasn't run since I bought it. About 8 years ago.

      It's also worth noting that I am heavily and unconditionally biased. I've had a lot of cars including some GTRs a fair while ago. I love my BMW's now a lot. They make no sense a lot of the time and the guys on here remind me regularly that I could get something else that does what I want better and cheaper. If you're going to take on an older BMW it's definitely a commitment. If you bail on it early you'll lose money and also the ability for it to put a smile on your face. Stick with it and it just gets better.  f**k I should get into advertising.

      Careful with posts like that around here without the flame suit on @cobo_11! 😂😂 My 330i journal is on here too. That car was so good and super reliable. We still have a 130i in the family which is almost identical to the 330i and easier to find in manual. It has also been almost faultless over the 6 or so years in the family.  I used to want an M car a lot more than I do now but if I'm honest and without trying to sound like a wanker, I can get such good performance and handling out of my 335 without needing to worry about all the crap that goes along with M car ownership. I don't need to worry about my bearings or subframe issues or the cost of replacing brakes or suspension or whether it has been impeccably maintained. And I can leave it places and not get upset when it's always filthy.
