R34 Gtt Induction Box Do It Yourself


Recommended Posts

Guest TR34GT

Hi SAU members.

As promised, my son and I now post the pictures and instructions for the DIY induction box, which is now finished, installed, and working like a treat.

The best thing about this exercise, was that the whole deal cost just $40. (with a few bits lying around too)

The car had an HKS Superflow pod filter, which we were trying to make legal.

The steps we took were as follows:

1. Buy a pices of 2mm thick cardboard from the paper shop.......around 400mm x 600mm - $2.00

2. Cut to the approximate shape to house the filter (car specific fit) using the existing GTT mounting points and trial fit until you get the approximate correct fit. The dimensioned template we made is shown in the attached pictures.

3. Buy a 900mm x 250mm x 2mm think peice of scrap aluminium polished sheet - $20

4. Mark out your template on half of the aluminum sheet and cut out with a jigsaw

5. Mark out the approximate fold lines on the aluminium

6. Fold by hand across the fold lines in the directions with a gentle constant pressure across a rolled flat edge

7. Drill 5mm dia holes in each of the end lugs

8. Trial fit a million times to get it right, and keep filing, cutting and massaging until you get the thing to fit perfectly.

9. Cut out two 80mm x 30mm peices, and round edges to for the top fixing mounts, bend at 90 degrees, after drilling two x 5mm holes in each lug side (see photos)

10. Fit top fixing mounts to side as shown using 2 x 5mm x 25mm high tensile steel hex bolts, washers and nuts.

11. Install your new heatshield using the existing mounting bolt and one new 25mm x 5mm dia high tensile steel bolt (see pictures) - $6

12. Cut shape of top out of same cardboard and trial fit so that it does not touch any of the chassis edges of the engine bay.

13. Cut out the top out of the other half of the aluminum using your template.

14. Mark out exact drilling points through top, to match fixing points and position in engine bay.

15. Trial fit another million times until its just right.

16. Remove all, and hang by lugs in a fairly dust free sterile environment (sure, we used the garage)

17. Spray Knights grey primer on all areas (touch dry in 15 minutes) - $7

18. Spray Knights engine enamal (gloss black etc) covering all areas till desired effect is achieved. - $7

19. Leave for at least one hour

20. Fit and glue on a rubber / foam edging across the bottom.

21. Fit all as shown, and dress with whatever vinyls you want (Mines in this case)

The project took a full day.

The installation is solid, with no vibrations or noise, and I think its now made that pod filter legal.

(At least we hope so)

Anyone wanting any help, or any additional information, just email me.

very nice job man, looks heaps pro.. Just a quick question. With the stock snorkel gone, where is the heatshield pulling air from? I know its pretty tight on the underside of the filter esp. with the stock cooler piping there, did you route a CAI into the guard too?

Also, did u notice a difference? is it quieter? more power?

very nice! i'll have a go at this myself.

do you have larger versions of the pics? more importantly pics of the measurements as they're too small :blink:

thanks

R-Spec,

Many thanks.

If you open up each pic in your browser and in the bottom right hand corner, increase the magnification to 200%, the pics should be ok.

One thing I didn't mention is that at the chasis mounting points, I used a 4mm thick x 6mm dia reinforced rubber fuel injection hose between two washers, around the 5mm bolts, as anti vibration mounts. Don't forget those.

I hope all works out.

Remember to trial fit 500 times and the result should be good.

Regards

Jim

Angelo,

On the GTT, there is a direct opening below the pod filter position which leads straight to the left hand grill openings in the front bumper and behind the the bumper.

No air piping needed. (I hope)

The noise from the pod filter was not reduced, however, if you were to also line the box with some sound deadening material on the inside, you might just quieten the ride.

As far as more power, there doesn't seem to be a difference, however, I'll try and route some 3" flex tubing directly to the pod, and see what happens.

I'll let you know.

Regards

Jim

Hello Guys

Here are some pictures of my DIY induction box and snorkel, following some of Jim ideas

Love this idea here, Gonna give this one a go but rather than make a wall in front of the pod(where the headlight is) ill leave it open so air can come through the head light area.

Wow your set up is so clean

Good work !

What intercool kit are you using ?

And did you have to cut a hole for the cold side ?

    • @soviet_merlin Thanks mate!  Nothing too major but will hold me up for a while. I've got lymphomas to get taken off the back of my neck and the middle of my spine which always conjures scary thoughts!  It sounds worse than it is. Yeah great, conjuring more rabbit hole deepening , just what I need! 🤣  
    • I'd argue the F50 kit I got is very good value. For ~2k I got the calipers (refurbed condition), adapters, pads, brake lines, rotors, and top hats. I think you'd be pretty hard to get Evo/GTR/350z brembos + the additional hardware for similar money. Used market for a pair of front calipers alone I've seen tend to run anywhere from $1500-2000 depending on condition.    That said, something like a GTR or 350z brembo is a lot easier to adapt to the Silvia. 
    • Is there a significant price difference between the Evo/gtr/350z brembos vs the F50? Looks amazing.
    • I was actually being a tightarse at the time LOL... My OCD is tickling me into running a 2nd 8AN Teflon hose all the way down and removing the 2x OEM hardlines. My other side of my brain is telling me to run 2x hardlines front to back (also acts as a fuel cooler, so win win).
    • As I mentioned in an earlier post, I had some trouble with the Silvia's brakes dragging back in 2023. I managed to sort it out then, but the same problem came back to bite me late last year. Just take a look at the picture – I had a feeling the handbrake was acting up again, and I was right. Anyway, I'd been wanting to upgrade to bigger brakes for a while. Not that the Silvia's brakes were bad, but it was more of a "want" than a "need", you know? It was funny, though – at the time, I couldn't find any Evo Brembos, 350Z Brembos, or GTR Brembos for a decent price (of course, tons of them popped up online after I already bought my kit!). I ended up going with an F50 Brembo kit, which came with adapters, brake lines, 330mm rotors, and top hats. The F50 Brembo caliper was used in a few other cars too, like the FPV. I also decided this was the perfect opportunity to ditch the Silvia's ridiculous rear brakes and that awful handbrake (some of you were definitely right about that!). I picked up some R33 calipers and all the necessary bits – rear drums, backing plates, and new hardware to refurbish the calipers. Of course, it wouldn't be a project without a few hiccups. Turns out the brake master cylinder was playing up and basically (to put it simply) keeping the brakes engaged. I had it overhauled, and after some adjustments, everything was working again. The whole process took a while, as you can imagine. To top it off, the front right wheel bearings were shot and needed replacing too. This is a rare occasion where I'm posting an update while it's all still fresh! These pictures were taken just this afternoon.
