It was on an page about retarded things have done to people. Amongst a bunch of weird things done to old cars their were these pics. I admit, I chuckled at its wrongness.

Was it you i met at Philip Island the other day or your Dutton co-driver. (Was with Troy in the S15) -
Mazda Rx3Gt Restoration

Dont look at me. I was never there. Dont blame me for the broken parts! ...sorry about breaking those parts -
Was working...try again

You seem to be giving a lot of thought to plenum size and runner length. Have you given any thought to injector location, number of injectors, throttle bodies qty and distance from inlet valves, types of throttle bodies... By saying you have looked at lots of manufactures I suspect you are missing the big picture, as they are pretty basic (cheap) manifolds made for what is really a limited volume application which is aftermarket Nissan RB world. If by big name manufacturers you are forgetting what Hypertune/Plazmaman, Greddy etc are doing and reading fluid texts and looking at ports prototype, rally, indy cars, JGTC cars etc are all doing then I think you stand a chance of achieving something better then oterhs are currently doing. Even then you will need a good enough understanding of what they are doing with their FIA restrictors and wat their manifolds are doing for their setups A good thing to consider , if you are committed to doing this is what in the world of racing runs an inline 6? Then from there what is running a turbo inline 6? Kind of obvious to start at JGTC RB26s that have some freedom on the inlet side of things.

I am with a few others in saying spend the money where you will see value and an increase in performance. But then a part of me is saying go for it, irrespective of the fact that you will probably sink $1500-2000 into it and go backwards (I have done the same thing ) The math is the math, and provided you passed 3Unit High School math you can keep pace with it. What Zebra is saying is correct, you need an understanding of fluid mechanics combined with your reading to understand the best place to start and tweak. Thats a start...you seem to be on the right path with a willingness to experiment...but I hope your tuner shares your interest. 3 or 4 tunes and you will have already sunk over $1000 into the exercise. I think for what you are trying to achieve you will struggle to see any increase in torque, response etc over std. Its much easier to extend the high rpm power with a manifold then it is to increase torque. I suggest if you really want to achieve what you aim then ask yourself what compromises do the std Nissan intakes make? Kind of obvious cost is one of the biggest compromises and multi throttle setups are where you will see the biggest gains. Whatever you design make it modular so that you can easily change runner lengths, bell mouth designs, and plenum volume. I suspect 6 throttles will be too expensive (or you can just go GTR inlets with a tweak to achieve what you want) so try twin throttle which will be a no brainer but if you want your engine bay to "look" good more then perform better then std then packaging will be a nightmare. I think with about 5K in development you would be able to get a good result but its from changing the whole methodology not just tweaking plenum volume and taking an inch off runner length

My car never rates highly in the most photographed or quickest stakes...but when the vid camera rolls due to how loud the car is it sometimes gets air time. SAU - Nats vid at 13 seconds and again at 1:05...where you see some white knuckle oppo lock mid corner -
Will look at the UK ones over the weekend , thanks

The New Soft Brake Pedal Thread.
Roy replied to Abo Bob's topic in Suspension, braking, tyres and drivetrain
I keep old brake pads for use when bleeding brakes after I have ripped everything off and broken lines. Throw the heavily worn pads in and bleed the brakes. The pistons will be well out of the caliper. Once you have bled the brakes I remove the worn pads... crack the bleed nipple with a hose on it and push back the pistons all the way into the caliper. I bet you see bubbles I then install my new pad on that side of the caliper and repeat for the side that still has the worn pad. Once you have pushed back all the pistons and have your new pads in then crack the nipples again and pump some fluid through. You will find when installing new calipers etc that there is air at the back of the pistons. When you bleed brakes you are bleeding between the master cylinder the the nipples on top of the caliper. if there is air behind the pistons or downstream of the nipples it isnt comign out unless you stroke the pistons all the way out, fill the backs with what fluid you can with bleeding and pumping and then with the nipple cracked push the pistons all the way back into the caliper. Any air will come out the bleed nipple with the flow of fluid rather than back up the lines to the master. Feel free to post blank cheques to me when this fixes your problem. if it doesnt do the trick then apologies for making you jack the car up and fluff around with fluid all over your hands etc...farking dirty, messy brakes can be bastards to bleed some times -

One of the few pics of my car I like...in the pits at PI -
Ever thought about doing a PS reservoir for an R32? I am powder coating my PS pump over xmas and getting it converted to banjos (provided I can get one with a large enough orifice and going full threaded lines and would be interested in going allow reservoir

Well now I get to wear my Renault jacket with a little more pride

Actually..you are right!

Yeh, seems rather petulant. I mean Vettel does it and the team all smile and say "naughty boy" whilst grinning. They tell Webber to back off at Silverstone and he still gives it a nudge for a lap or two. The drivers are still out for themselves and not the team. I hate RBR now so fark them. As soon as Webber steps aside I will not give two sh1ts about what happens to them.

Top RB20 Club... do you have over 260rwkw?

As per above here is some footage of the old girl on song at Phillip Island. -
Thanks for the PM re airbox. I will take it. Can you let me know where you are located so I can suss out how to arrange collection

So how is the tuning coming along? Do you know what was done in the way of matching combustion chamber to the bigger bore? Was the squish removed etc?
-
It is sounding a little off at the moment. It has got an exhaust leak somewhere....will be mega pissed off if the 6boost manifold is warped or cracked. Everything is tight and looks ok so need to have a look over xmas

Was watching Goodwood 2011 the other day and noticed just about every car was using a GoPro HD. So the footage seems good enough for a BBC production. Notice they use them on the handlebars of bikes etc on Top Gear as well. The audio is rubbish. We were using one on a rally car on the weekend and even in the car they simply pick up too much background noise, something to do with the frequency of that noise being recorded better then an 4cylinder pinned to the floor Must be some software out there to filter out the "noise"

Yeh, the 4 door? I was the drunk out front of their place at 11pm Sunday night. I was looking it over when they saw me from their living room and one of them came out and chatted. They had a gearbox problem but got it all sorted and finished the event.

Weather was horrible at the Alpine as well. We lost both our cars, one ate a tree and the other went head first roll over into a gorge Damage was freakishly small for the roll over (thanks to the soft brush it went into) but the tree eater will need some work/time.

So all those with race seats can you do me a favour and go sit in them and throw a harness over and let me know where the harness opening in the back of the seat is relative to the top of your shoulders? Was at the Alpine Rally on the weekend and was speaking to a bunch of people and seems my problem is not a problem in the eyes of many
