Im thinking of making my own fibreglass airbox based on the stock one, but to accommodate a pod inside it plus induction from underneath rather than the stock snorkel.

anyone got any tips for me? love to see some aftermarket versions to give me some ideas!

Cheers, Bart.

i started once

cut out the templates out of cardboard

masked the area off with think layers of tape to create a buffer between the painted engine bay and where the glass would be layed.

then i ran out of time that day, few days later the tape had all come unstuck so i ripped it out and just made an alloy one up.

this idea is probably the BEST option to take to ensure a completely sealed unit from heat. and once you peel the cardboard off the outside of the box you make, just line it with a heat shield material and it will be perfect.

bj_dove Dude ! Where are you located ? I have one completed in fiberglass. It uses the original snorkel as well. Took me a very long time to get exactally right and Im not keen on posting pics because of people copying the style.

I am still trying to find one that suits what I want. I am thinking about a Plazmaman alloy one

Why don't you want people copying the style? Isnt that the idea of the forum to help each other out?

Oh yes ! I have helped a lot of brothers out on this forum for free and at my own expense as well and not thought twice about it cause thats what you do for people in a club. I put hundreds of hours into the development of that air box and I should just give it away ????? And dont get me wrong I aint after any financial gain for what I do and if someone asks to see it arrange to meet me and see it in person and have a chat on how it was done and I'll help out with them making one for themselves. Im cool with that.

No worries mate... understood.

I was just really keen to see it, the more ideas I can get the better.

Yeah I'd love to have one of these fabricated to suit a pod but to use the factory snorkel. Ive seen a few around for sale but im waiting to see a bulletproof version for example the other ones ive seen are not fully enclosed and allow hot air in or you cant use the pod brace to make sure the pod doesnt move. havent seen any around yet. I swear if someone sold one of these they'd make a killing.

What a coincidence! I've recently started making a fabbing a FULLY SEALED airbox for my R33. Some of you may know of the gauge pods that I make, but in a lull with getting cars and designing new gauge pods over the last month I've started doing an airbox in fibreglass - that uses the factory bolts to hold the box and the pod in place. I have a front mount intercooler so this won't suit a car with the factory snorkel or factory intercooler return piping. I have a mate who wants one for his standard intercooler fitting as well and who knows - I may end up selling them if there's interest :rolleyes:

I'm moving slowly on the fabrication and have only done the main box part and no lid so it's not finished, but I have no problems in posting some pics if anybody wants. The lid will be sealed for my design but will incorprate the use of the factory snorkel for the other one.

I'll try and get the box to reasonable fabricaiton point and upload some pics this week. As PLYNX said, it does take a very long time to get it all lined up right and fitting well.

For the benefit of bj_dove (originator of thread) and anyone else who's doing airboxes, I've been trying to think of ways to secure the lid. Anyone got any (simple & effective) ideas? I don't like the idea of using screws in fibreglass because you may eventually strip any thread you made. I thought of actually mounting magnets/latches (the ones you find on cupbaord doors) to keep the lid on.

Comments?...

you can buy tool sets that are half fivet/half nut.

basically you press the threaded section into a hole, then you can use a normal bolt. kinda hard to describe, its a bit like a threaded eyelet.

I also started looking at my air box again after a bit of a break and was going to use small cabnet latches to hold the lid down. These are similar to the lockdown clips that the original air boxes use and are available from Bunnings. Three will suffice on my airbox as one side slips under the front gard. I was really after the speed of removal that the original latches have. also the one I have built is for the original intercooler piping.

Quick related question here:

Would there be any merit in fabbing up a fibreglass snorkel to replace the stock one while using the stock airbox?

Basically to get a ram intake effect?

Just noticed that the stock one has airflow dividers and looks like it might be a bit convoluted in terms of flow, thought it might be possible that a custom one with a bigger opening perhaps extending a little lower down into the frontal airflow could be beneficial?

For the flow through factory snorkel - I agree that the factory snorkel is not exactly the best internal design especially with the hump in it that goes over the intercooler return pipe. This could certainly be improved to become a "big mouth" design to catch more frontal airflow and smoother internal flow to the stock air box.

As for getting the air into the snorkel, of course the bigger opening in the snorkel the better but with the factory snorkel, the only thing that will really help flow INTO the snorkel would one of Bass Junkys air guides (also in the Fabrication section). These are very well made and a great item btw

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.

      After market rear camber arm adjustment

      By Duncan · Posted

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      After market rear camber arm adjustment

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      By Duncan · Posted

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.
