Depth is approx. 90mm at the front carby and 75mm at the rear leaving around 30mm clearance between the lid and the strut tower (on Zed)
I don't have the time to collate interest so if someone would like to take this on and collect deposits, once a $1000 is raised I'll get the mould underway (fully refundable if the deal falls over for what ever reason).
Backing plates will be blank to allow multi use applications, as I'll need to remove the entire induction system to take the airbox off the carbs, if/when enough interest is raised I'll start the ball rolling again and confirm pricing, hopefully the $400 each mark should still cover costs.

The benefits as stated previously are more mid range torque, far less noise and you can plumb in the crank case and rocker cover vents to comply with EPA regs (catch cans are not EPA friendly). The set up looks factory fitted and can be used with a 280z filter housing (from the US S30 with the injected L28 easy found on ebay) which bolts straight in front of the radiator and far superior to pod filters (again proven by dyno testing) .
Anyway guys I'm happy to go to the effort to get the air boxes made but l'll have to leave it up to one of you to champion the cause and collate interest and chase deposits.



cheers

Alan

Alan it's great to see you are trying to make this happen, I myself would be interested if they fit a set of Triple Mikuni 44 carbs? However as odd as it may sound I actually would prefer it as pressed metal as opposed to carbon fibre to give that true stock look.

I don't know how difficult these are to get? But would imagine that in Japan there would be many interested (if it's not possible to source OEM anymore).

Anyway you can stick me down as another interested party, when if this goes ahead.

Hen teeth, rocking horse shiver, I did manage to find one new on an auction site but 90,000 yen before agent fees, shipping etc so that put it at over $1400NZD at a guess....I too would like a metal one for the true period look but that is going to be near impossible.

So count let go lads.

Thanks Alan for taking the time to grab the measurements.

I'll confirm my interest after doing some measuring on the weekend.

The air box is fitted to my Triple 44 Mikuni's so yes it will definitley fit , and Webers as well...........the variable is the length of the intake manifold.
If you have a minimum 120mm between the carb throttle body and the strut tower it will fit

The plan was to make the airboxes with a solid back plate so it can be used for 40's, 44's 45's etc,  so it can be used on Dellorto's etc as well.
I can make a template for the holes so it will be easy to mark out the back plate for drilling to suite Mikuni 44's and Weber's will be very close.

For the period look, you can get them painted to a colour of choice rather than leave it in natural C/F as the finish would be clear gell coated and smooth.

cheers

Al.

I was thinking that, I really like the orange air box on the standard twin SU's in the engine bay (or as my friends call it the 'guitar'). A red air box on triple mikuni's wouldn't raise any eye-brows should the kind constable plod pull me over for an inspection. It would I imagine look very 'correct'. It's all about stealth with me ;).

I was pulled over earlier this year for a road side RBT and road worthy check and apart from the wind screen washers not working (due to a kink in the water line) all was fine .........nothing was said about the airbox and induction system on my Zed.
The first thing checked was the crank case vent which I pointed out was connected back into the air box as was the rocker cover vent, I also had a noise test and all good .

Is this sort of testing happening more often in Australia these days? I feel they are cracking down on modifications etc.. In recent years as a way of deterring hoon behaviour. Just another reason to make everything legit.

Sorry to say I am out. Now the why I am out.

I have just managed to secure a NOS one of these Prince GTB airboxes for $450 AUD - I still have to pay for shipping from Japan to me here in NZ and import duties. But I am one happy bloke.

I hate you where did you find it? I typed prince in on Yahoo auctions and got nothing back.

I'll swap you 12 L14 rods for it? Haha.

That's a score mate I would be well happy with that too!

lol hmm let me think about that....NO....these days I would not use a 35+ year old rod in any motor I build if I want the L14 spec I would have custom ones made if none where available.

It was on Yahoo but you needed to search for S54B ie the model code for the GTB. It had a buy now of Jp Y90000 but it was a no reserve auction with a start bid of Jp Y39000 and my agent was the only bidder :) so a very good find and purchase.

I still have to pay my agent his fee and shipping to me which is an approx $150 AUD but I am more than happy given it is NOS aka new in the factory box. These are very rare these days. I would love to own a real S54B. One day you never know

Well done mike, I was very nearly your bidding competition though, I was waiting for some cash to come through but it didn't happen so I had to let it go. I think the seller actually started the bidding at 30,000 yen then bumped it to 39, maybe he was worried no one was going to bid ;)

Thanks for not bidding Mark  8)

No Alan it does not come with the 90 elbow so I will have to sort that out at some stage.

Right I know I said I was out as I have one of my own coming from Japan - I have decided if we can get the numbers I would still want a copy version too :)

So I am in again :D - I have managed to get another member interested also.

1. Nzeder
2. Gav240z
3. BAM083
4. acf321

Anymore - I personally don't care if it take 12 months to get the number but as long as we do it would be shame to have such a nice looking/and proven item not available to us. There is no perfect solution as each engine build will be different but the setup Alan came up with looks good, works and works well.

The thing I like about this setup is it works with the longer intake aka redline and cannon as not many do. I did consider another unit from Japan that was designed for the S20 powered cars aka GT-R and Z432. Others including HS30-H have successfully installed these units on the L-Gata engine by flipping the unit. These units from Japan are not cheap but these come with built in ram tubes/trumpets and again work well on the cars.

Here are some pics of HS30-H from classiczcars if you want to take a look - however from the looks they will not work with the redline/cannon length type of intake manifold.

This is why I am keen on this setup - it works on the longer intake manifolds and my engine builder (when I start my engine build) wanted to try the long units.

Bump to see if others are interested in this still?

Also my genuine Prince GTB airbox (or as it states on the part number Duct Air) arrived today and I see why Alan needed to modify this to work as the Prince G7 triple manifold must have each carb on a slight angle to level the carbs out (assume the G7 mounted in the S54 is higher in the front vs the rear).
