I know most of you are going to think I have too much time on my hands, and now with uni holidays I DO! ;)

Since im waiting to receive my FMIC Kit, I been searching and pondering a method of making a CAI system using a pod that is also legal! I have read 100's of threads on partitions and home made air boxes but not one of them tickled my fancy. So i have put pen to paper (mouse to mouse pad :D) and thought of a very easy, simple yet efficient closed CAI system...

What you guys think??? This should be legal (in NSW) cause the Pod is covered right??

Please feel free to critique :D

Regards,

Sarkis

Your only problem now is getting enough air into that enclosure through that pipe.

I made my own setup similar to yours (without the surrounding - just the cold air intake) from stock intercooler piping. Works well, but I think that if I sealed the pod off completely, then it would have an adverse effect (not enough air getting in).

Maybe come up with a better intake system that will guarantee more air going to the pod.

I'm pretty sure if you went 4" or even 5" it would be more then adequate air supply for the POD... Either way its a MUCH more flowing design then the factory air box... Even use mandrel bends with the intake pipe to allow more flow...

By sealing off the POD in my design, you will prevent any hot air being sucked in therefore your air source is outside the engine bay... not to mention it makes it legal...

Cheers

yeah, nice theory. my only suggestion would be to leave a decent size hole (or a few smaller holes) at the bottom of the 10" pipe so as it can suck extra air. and being at the bottom it will be less visible to the boys in blue.

True... but that means drilling out a whole that is going to be 4" - 5" something I don't really want to do. Why not just utilize the 3" hole that's already there provided you have an aftermarket FMIC.

Thanks Mads... I will defiantly build a CAI after my FMIC install and I think this will be the best design so far... I personally wouldn’t cut a hole on the bottom but rather add an additional intake pipe :D

Cheers

you could get some flexible silicon piping from autobarn for about $20 to use as the additional piping, and just run in down inside the engine bay to the front bar.

i just have a cold air duct coming up from the front bar through the existing smic hole to my pod, but i have it open as well. up here in freezing QLD you don't have to have the pod enclosed, just a fixed mounting bracket.

How much they selling that set up Sydneykid? Where can I buy it from??

Cheers

:D cheers ;)

for flexible pipe... check out clark rubber - trust me you won't be dissappointed!

i have a CAI setup with the stock airbox on my car - a pipe leading goign from the front of hte car into the airbox... i have put a funnel at the front end to maximise ram air :D

cheers,

i don't have one up here, but he should have one down there. we don't have many good shops up here, but we do have one of the highest rating autobarn in australia here though, so that helps when it comes to getting parts. they know what they are talking about. the new owner has owned a few skylines and other imports so he has started stocking heaps of bits for them, like intake plenums, turbos and intercoolers.

anyone know where to get a cheap bellmouth like in that pic, i know GCG have them,and HKS make them for thiers turbos, but the cost is ridiculous.

then make up a custom flexi pipe the std location...

i have everything else, just need a bellmouth with a 100mm hole.

K&N sell that setup for about $260, We have had a alluminium metal spinner make some for us to suit a 3" by 6" pod filter. We have had him modify it to suit jap cars with air flow meters. Look good and work very well and are legal. Ill attach some pics of one fitted to a SR20 in a 1200 ute. We sell these for $180.

i just want the bellmouth thats at the end of the black hose(opposite end to the pod)

There is an old trick for this =

Get a piece of PVC tube with the diameter you want, aheat gun and a funnel

Place the PVC pipe upwards, heat the end with the heat gun and use the funnel to push down on the pipe which now hot, will mould to that shape giving you effectively a bell mouth. Very cheap and from the results, just as effective and apparently makes a big difference!

Or if you wanted to get really tricky you could hunt around and borrow several different funnels and carry out the procedure afew times gradually increasing the funnel size to give you a smooth curve = True bellmouth

hehehe thats a pretty good trick, only thing is that the bellmouth will be visible and i dont think pvc will cut it.. might look into it anyway :D

    • Thanks, I removed the fuse and the relay from the car and made my own circuit with them to test them with a test bulb.  I will look for the wiring diagram and go from there.
    • Jdm DC2R is also nice for a FF car compared to the regular hatches of the time.
    • Now that the break-in period for both clutch and transmission is nearly over I'd like to give some tips before I forget about everything that happened, also for anyone searching up how to do this job in the future: You will need at least 6 ton jack stands at full extension. I would go as far as to say maybe consider 12 ton jack stands because the height of the transmission + the Harbor Freight hydraulic platform-style transmission jack was enough that it was an absolute PITA getting the transmission out from under the car and back in. The top edge of the bellhousing wants to contact the subframe and oil pan and if you're doing this on the floor forget about trying to lift this transmission off the ground and onto a transmission jack from under the car. Also do not try to use a scissor jack transmission lift. You have to rotate the damn thing in-place on the transmission jack which is hard enough with an adjustable platform and a transmission cradle that will mostly keep the transmission from rolling off the jack but on a scissor lift with a tiny non-adjustable platform? Forget it. Use penetrating oil on the driveshaft bolts. I highly recommend getting a thin 6 point combination (box end + open end) wrench for both the rear driveshaft and front driveshaft and a wrench extension. These bolts are on tight with very little space to work with and those two things together made a massive difference. Even a high torque impact wrench is just the wrong tool for the job here and didn't do what I needed it to do. If your starter bolts aren't seized in place for whatever reason you can in fact snake in a 3/8 inch ratchet + 6 point standard chrome socket up in there and "just" remove the bolts for the starter. Or at least I could. It is entirely by feel, you can barely fit it in, you can barely turn the stupid ratchet, but it is possible. Pull the front pipe/downpipe before you attempt to remove the transmission. In theory you don't have to, in practice just do it.  When pulling the transmission on the way out you don't have to undo all the bolts holding the rear driveshaft to the chassis like the center support bearing and the rear tunnel reinforcement bar but putting the transmission back in I highly recommend doing this because it will let you raise the transmission without constantly dealing with the driveshaft interfering in one way or another. I undid the bottom of the engine mount but I honestly don't know that it helped anything. If you do this make sure you put a towel on the back of the valve cover to keep the engine from smashing all the pipes on the firewall. Once the transmission has been pulled back far enough to clear the dowels you need to twist it in place clockwise if you're sitting behind the transmission. This will rotate the starter down towards the ground. The starter bump seems like it might clear if you twist the transmission the other way but it definitely won't. I have scraped the shit out of my transmission tunnel trying so learn from my mistake. You will need a center punch and an appropriate size drill bit and screw to pull the rear main seal. Then use vice grips and preferably a slide hammer attachment for those vice grips to yank the seal out. Do not let the drill or screw contact any part of the crank and clean the engine carefully after removing the seal to avoid getting metal fragments into the engine. I used a Slide Hammer and Bearing Puller Set, 5 Piece from Harbor Freight to pull the old pilot bearing. The "wet paper towel" trick sucked and just got dirty clutch water everywhere. Buy the tool or borrow it from a friend and save yourself the pain. It comes right out. Mine was very worn compared to the new one and it was starting to show cracks. Soak it in engine oil for a day in case yours has lost all of the oil to the plastic bag it comes in. You may be tempted to get the Nismo aftermarket pilot bearing but local mechanics have told me that they fail prematurely and if they do fail they do far more damage than a failed OEM pilot bushing. I mentioned this before but the Super Coppermix Twin clutch friction disks are in fact directional. The subtle coning of the fingers in both cases should be facing towards the center of the hub. So the coning on the rearmost disk closest to the pressure plate should go towards the engine, and the one closest to the flywheel should be flipped the other way. Otherwise when you torque down the pressure plate it will be warped and if you attempt to drive it like this it will make a very nasty grinding noise. Also, there is in fact an orientation to the washers for the pressure plate if you don't want to damage the anodizing. Rounded side of the washer faces the pressure plate. The flat side faces the bolt head. Pulling the transmission from the transfer case you need to be extremely careful with the shift cover plate. This part is discontinued. Try your best to avoid damaging the mating surfaces or breaking the pry points. I used a dead blow rubber hammer after removing the bolts to smack it sideways to slide it off the RTV the previous mechanic applied. I recommend using gasket dressing on the OEM paper gasket to try and keep the ATF from leaking out of that surface which seems to be a perpetual problem. Undoing the shifter rod end is an absolute PITA. Get a set of roll pin punches. Those are mandatory for this. Also I strongly, strongly recommend getting a palm nailer that will fit your roll pin punch. Also, put a clean (emphasis on clean) towel wrapped around the back end of the roll pin to keep it from shooting into the transfer case so you can spend a good hour or two with a magnet on a stick getting it out. Do not damage the shifter rod end either because those are discontinued as well. Do not use aftermarket flywheel bolts. Or if you do, make sure they are exactly the same dimensions as OEM before you go to install them. I have seen people mention that they got the wrong bolts and it meant having to do the job again. High torque impact wrench makes removal easy. I used some combination of a pry bar and flathead screwdriver to keep the flywheel from turning but consider just buying a proper flywheel lock instead. Just buy the OS Giken clutch alignment tool from RHDJapan. I hated the plastic alignment tool and you will never be confident this thing will work as intended. Don't forget to install the Nismo provided clutch fork boot. Otherwise it will make unearthly noises when you press the clutch pedal as it says on the little installation sheet in Japanese. Also, on both initial disassembly and assembly you must follow torque sequence for the pressure plate bolts. For some reason the Nismo directions tell you to put in the smaller 3 bolts last. I would not do this. Fully insert and thread those bolts to the end first, then tighten the other larger pressure plate bolts according to torque sequence. Then at the end you can also torque these 3 smaller bolts. Doing it the other way can cause these bolts to bind and the whole thing won't fit as it should. Hope this helps someone out there.
