Yesterday i went out and i couldnt find that thermofoam anywhere.I went to rocket and bought some stuff called thermo-mat.Its foil on both sides with what looks like fibreglass matting in the middle.Cost me $50 for a 120cm square sheet of it.Anyway i measured it up,cut it out and put it in the CAI.Havent really driven it much since then but surely it would do something.

How did it go ducting the air in from the side? Do you know how the guy that did that find it? Where would the CAI hose run if I did this?

I would prefer to use the stock intercooler holes, but I have the Blitz kit which uses them, and I don't have a stock snorkel.

sorry to be a wet sock, but, that is still going to draw heat in from the headlight at night, is it not?

Im in the process of trying to "think" up a completely "sealed" design, with only one air intake through the base to use the stock intercooler piping hole as a cold air intake point. Will be fabbing it up at work (work at a sheetmetal place :dry:). Will be a bastard of a job i think =[

Compared with engine bay temps, I think the heat from the BACK of the headlight would be negligible. Remember that one day you will probably have to change a headlight bulb so make sure if you put somethign behind it that it is easy to remove. If you are that worried about it I would just tuck some foam in behind the headlight and secure it at the corners.

Hi mate,

Where abouts did you get the ALUCOBOND (im in tassie 2)

cheers

Well so i was sitting on the net, going over all the CAI designs, ones you can buy and so forth. I remebered that a member of the forum had some templates. SO got those and went to work.

My dad and I started in the morning on boxing day, figured we would take it easy, well 4 hours later, and a six pack of beer, and HAY PRESTO, here is the finished result.

The box case is made out of a product called ALUCOBOND, it's a 1mm ally, with 3mm PVC, and 1 mm ally again. You can buy a thicker ones if required. The inside is lined wiht a THERMOFOAM, it's a 15mm thinck high density foam with silver foil, excellent R values, to miniminse heat transfer. I noticed a 6deg C after introducing the foam.

The air is introduced through a 2'5" pipe from the front of the bar and blows straigh into the box.

SO far the results are great, the car is a lot more constant, if you stand in trafic, the heat lag is gone. The air is nice and cool, and the car is a lot more responsive. Fuel ecconomy is up, and the pod noise is reduced to a more acceptable level.

Only down side, on a cold morning, the dam thing hits R&R so dam quick, as the air is so dense, and the box together with the FMIC, really increase the air flow, hence R&R.

I have the templates available, if people are interested, but i modified mine as i went allong, i found that each car is different. I have done this to my friends R33 4door, with an APEXI filter, and we had to extend the main box body and make a different cover top.

I did mine by making the side first and then making up a pattern to fit for the top cover. The side of the box is held in place by two brackets riveted to the side of the box, and bolted to the car using the stock airbox mounting holes. The top is slid inot place under the front panel, and then bolted through the top, into some brass L-brackets. I then finished the alluminium by brushing it with fine still wool. I did have it polished, but it was VERY hard to keep semi clean. Total cost, ALUCABOND, free i got offcuts, Thermofoam $36 per meter, and all the other bits and peices i already had, so that is DAM Cheep.

Tell us what you think.

woolls, i'll get some on monday, you can only get it form TasCon on argyle street and i know the guy so i can get it for free, or you can go in and for a carton of beer you can have as much as you want. offcuts ofcourse. PM me and we'll chat

Any tiny bit of heat you can get rid of can help, the colder the better :)

Either the foam or just a detachable/screw in section.

Even with the thermo foam etc in place you would still get a lot more heat coming through the shield than you would get from the headlights,

If you do decide to shield from the headlight please post results. I would guess there would be no noticable difference.

the amount of heat of the headlights would be sweet F.A. the rear of the light is plastic, which doesn't conduct heat well. if you put you hand over the back of the light it will only be slightly warm.

you would get more heat radiating off the intercooler pipe that runs from the turbo to the cooler.

as for making a completely sealed box, i'm undecided on this. sure you wouldn't get any hot air coming in, but if you don't have a big enough feed at high rpm it may end up being a restriction. if you don't have it set up right at WOT at high rpm you might be only getting 90% of the air that could be used. if it isn't fully sealed in the same situation it will be able to get 100% air. and the small amount of warm air is going to be better than not enough air.

Agreeing with MAD082 that plastic is a bad conductor of heat, that’s why I decided to make my CAI box out of acrylic. As most stock CAI boxes are made of a plastic which must have some purpose or reason. Otherwise wouldn’t all major car manufacturers make them out of some other material?

looks great mate...well done.

as for heat from the lights...lol it would contribute sweet FA and only be an issue when the lights we ON...

not withstanding...the amount of air comming in and the heat it would disipate through the plastic backing would amount to FA.

    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
    • So, a bit of a side trip, but one that might be interesting for people with JDM cars and japanese head units. I know @Pac previously posted about a carplay/android auto adapter he installed which used the AUX input, and @V35_Paul put in one of the Tesla style units that replace both screens. The option I went with was a Lsait LLT-YF-VER5.87_2 (https://www.alibaba.com/product-detail/Lsailt-8GB-Android-Multimedia-Interface-for_1601187633672.html). Price was $1,150 for a single unit although they are much cheaper if you are willing to buy 2....$857ea. Make you you get the version 2 not version 1, it is faster and has a better UI - this is the manufacturer listing: http://www.lsailt.com/product/348.html. BTW if you've never bought from Alibaba before, don't be concerned....these guys can't stay in business unless they are responsive, ship fast etc, they were excellent (probably faster shipping than most local places) So, this was my task for a lazy Sat afternoon....looks complex but was all done in a few hours (it probably helps that I had some of it apart before so it was a bit familiar). I also decided to add a HD USB drive recorded at the same time and the unit also supports an aftermarket reverse cam (if you don't want to retain factory) and also AV in and HDMI out It looks much worse than it is, in fact in was genuinely all plug and play (no custom wiring at all). This video was pretty good (skipped a few steps), unfortunately they are an Aussie seller but no longer sell this unit (I guess Carplay/AA adapters are easier to install and much cheaper) https://www.youtube.com/watch?v=T5hJfYOB8Dg
    • That still isn't a lot to go on. I don't have a Y50 Fuga Head Unit wiring diagram. I can say that a lot of nissans of that age shared head unit plugs, so if you are in Australia something like this would probably help: https://aerpro.com/app091# You plug that into the car loom, then either plug the head unit ISO into that (if it has ISO), or you buy and ISO adapter harness that you wire in. Bit of stuffing around, but once you have ISO its easy to change things in future.
    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.
