Help Fabbing Airbox For R32 Rb20det

[hobbsy]

hi guys, I just bought a R32 GTS4, its got a pod filter so I want to box it up.

does anyone have some examples of designs they could show me? especially for intake.. i don't really want to cut any holes in my chassis/wheel arch if i can avoid it.

the cars at the mechanics at the moment so I can't measure it up, but i was just planning to do a 4 sided box sitting against the chassis with a 3 inch hole in the front to run a piece of pvc pipe or some form of tubing out to the front bar. where do people usually get the air from? does anyone have pictures of the stock airbox so i can see where it gets air from?

I work at a fabrication shop so i probably have access to anything i would need.

If you don't want to cut any holes you will probably need to use the stock hole under the headlight.

You can get an r32gtr or r32rb25 intake snorkel, which uses the all of the stock hole unlike the factory rb20 snorkel.

Also you can take the nose, that the snorkel fits onto, off your factory airbox as it is made of metal and rivet it to the front of your new airbox in a position that aligns with the factory snorkel.

It's up to you if you want to use the gtr/rb25 intake piping that attaches in front of the snorkel.

I've thought about using the gtr/rb25 intake section that bolts to the front bar reo and blocking off the intake hole and then plumbing an air scoop into the fitting that used to go to the gtr/rb25 resonator chamber.

The thing I wasn't sure about was whether the resonator duct was big enough.

i'll probably just run some of that cylindrical plastic air ducting stuff from a hole in the airbox to the factory hole with a heatshield along the side of it, or something like that.

Yeah pretty much what i had in mind myself, engine going back in this weekend so hopefully finish off the box while im at it

GMB ... ever finish your Airbox?

here's an example of my crappy diy for the time being. need a nice 3" pvc pipe but got this one for free, so cant complain.

[Craved]

DMR - that is actually a clever way to do it, looks std

shame this type of option is alot hardcer for the 33 guys out there

[funkymonkey]

in the process of fibreglassing one for mine. I've got a plug, now I just need to make a mould and then lay up some fibreglass on it. Will post a DIY with pics when I'm done.

hey this is my airbox shitty pics i know , its all outta brushed stainless . its great stuff!

[GTST98]

oh and ive got a front mount so there is one spare hole where the pipe work normally returns to the engine so i used this as my air feed from down next to the bliker in the front bar , ive used that flexible tube from super shit AKA super cheap , the stuff the streaches then stays where u leave it , its great stuff

[ACTIV32]

i made one those covers but came to the conclusion to put my pod outside the car i relised that it sucked way more cooler air just thought u like to know

i also have 32 gts4

hi i own a r32 and i made an air box out of polycarbonte (lexan) which is clear so you are abl to see you pod filter

is an aftermarket airbox defectable??

[TurboX]

I think the std airbox with K&N and the triangular metal entry pipe beaten out to cylindrical,

inside a five inch plastic duct molded to fit into the entrance along side the headlight is the ultimate.

In the pic above ( post #7) you can see the two rectangular holes near the headlight,

- cut the middle bit of metal out making it one HUGE opening for the intake plastic duct molded

to the same shape and protruding out a bit and wrapping round to make a smooth air path!!

if ur after ideas for an airbox heres mine, on a r33.

2pieces of allie. top of one is press bent. then small rivets hold on threaded fasteners, so screws can go on top for ease.

i also have the box lined with heat resistant, and reflective foam. works a treat

im having trouble thinking up a heat shield design for my r32, the pod is basically sitting upright because it has to fit between the cooler pipe and the a/c pipe i think it is. and im not to keen in extending the rubber intake pipe due to keeping things as short as possible for response purposes.

does anyone else have this problem?

any pics to show a design someone has come up with, to counter this problem and still keep things cool?

cheers

I'll get Sl!m to post pics of his airbox in here.

As for shorter piping from the pod to the turbo - this is not going to affect the response of the motor.
