Haven't found a specific thread yet for this cold air intake mod. Anyone care to share what they ave done to get colder air in, or if thy ae instaled the official "powerduct"?

Bet there's a bunch of people who've made there own.

Share your work/secrets!

Your request is my pleasure.

I fitted a piece of foam glued to a piece of L shaped plastic like the other plastic I used to seal off the front.

Cheers

I thought I saw that a while ago! Nice work; I like the home job coz thats what i wanna do. what about the air filter? What did you use there? Are you actually getting colder air u reckon?

I made one by using a tub (like an icecream tub but actually had nails in it) about 140mm square behind the LH headlight cut a hole in the base near the top and fitted a one litre castrol oil container (so that it was also black) with the top and bottom cut off going into a hole cut in the front of the top of the standard airbox. Sealed all joints except the one going into the airbox to make it easier pull apart and remove when necesary.

Gave me an extra 20KW and cut a second off my 1/4 mile time. (Just kidding). No way of measuring the improvement really but plenty of air gets by the headlight at speed. Unfortunately the LH corner took the brunt when I wrote off my S1 so now I will have to start again. This time I also have an air diverter and scoop (from the group buy) to fit so that should help.

I haven't actually measured the temp difference but I am sure I am getting more cold air. The difference is noticeable at the top end. A bit less breathless at higher RPM.

Along the leading edge of the bonnet there is a rubber seal that runs most of the width of the bonnet. You need to either cut off about 4 inches on the intake side to make sure the cold air can get in. Or you can do what I did and that is fit a piece of wire inside the rubber seal and bend the rubber with the wire inside 90 degrees so it is out of the way.

I am using a K&N filter. I am not sure there is any real difference with it but at least it isn't a reason to slow the air intake.

or you could just get lazy and buy one!!!!

be prepared to get bent over by Nissan though

I am ready and lubed up :(

I might get one put it when I take it for it's 60,000 km's service which is due in about 1500km's.

It's close to $200 isn't it?

I want to keep this thing genuine, has anyone got any pics of what the actual powerduct looks like?

Geniune, pfft. Genuine rip off... A little bit of your time, some pinchweld and some black spraypaint.

Spend some time making something for your car, it's good for the soul.

Save your money for petrol :( .

Either that or eoi for stainless steel structure, tig welded, bolts, pinchweld, ready to fit; $100.

The queue begins here, I'll post pics if people are interested.

Is this the thingy jig were talking about?

Has anyone gone down the "cold air induction" road? If so how much did it set you back, which system did you use, and what was the performance gain like?

That is the item. The factory one is a very neat piece, I just used a piece of flat 1mm stainless, rolled the curve into it, tig'ed a lip around the edge, used a piece of pinchweld from Clark rubber. Rolling the compound curve was the hardest part of the whole exercise.

It was the first thing I did when I bought my car, so I'm not sure of the gain, but too much cold air never hurt an engine :( . Nice induction roar tho'.

I agree with danny that it looses a small amount of bottom end power but the upside is the top end.

Consumption may be a bit worse. Maybe I will change it back and watch the economy for a while.

actually good idea i might run a full tank with a pod filter and full tank with no filter and see the difference

the only good thing that came out of it was that my wife didn't speak to me for a week....I didn't have to have 1 six pack holiday* all week!!!!

*Definition: Six pack holiday - Go to the closest bottle shop(1 minute away for me) - buy six pack - drink six pack before arriving home so the wife does not see - wait ten minutes - your on holiday! - e.g. wife's voice sounds a bit BLAH BLAH BLAH BLAH!!!....GOLD I say!!!!

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      By Duncan · Posted

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
