R34 Gtt Induction Box Do It Yourself

[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.

mate this is awesome.

well done and thanks.

[R-SPEC]

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

thanks

[Angelecles]

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?

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.

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

I lined my carbon airbox with sound deadiner and found it no quieter.

for vic peeps, if you're running a FMIC, even having a boxed pod is illegal yeah?

[Flash89]

where would ya get a aluminum sheet from and you can seriously cut it with a jig saw wow

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 ?
