Can R32 GTR airbox be improved?

[t01-100]

I need to keep the standard R32 GTR airbox in my car, has anyone played around with these to improve the air flow?

The dyno killed 11kWs straight up with between running just the AFMs (unfiltered) and running the airbox.

Cut the front of the bottom section out. Works well on mine.

thanks mate, will pull it off and have a look. will it need a duct?

is your box pressed steel, mine is top part pressed steel and the bottom part forged alloy.

Drive it around, get it all hot, stop-start traffic, etc, etc. And i think you'll find the air box will win out.

You can try and set up some CAI ducting to supply more air to the box's inlet to get some gains, plenty of threads on that around.

There is a big ass resonator that hangs behind the front bar. Mine was filled with water.

The resonator inlet to the bottom of the airbox is a circular cut out of around 5cms diameter.

If you want to you can enlarge this hole to say 8cms and duct from your front bar vent to the side of the FMIC directly up into the airbox

I have removed the resonator but have fitted an oil cooler there

Forged Alloy bottom section and steel top???

What sort of box have you got???

a strong one!

I know the tops are pressed steel, have not investigated the bottom sections though...

Does anyone have pics of a GTR32 airbox out of the car and in pieces ?

Thanks Adrian .

I thought they would have been plastic like the GTST ones..

odd

[FATAZZ]

am i better off putting my gtst standard airbox back on n cutting holes in it?

On mine I removed the resonator but kept the pipe that joins it to the snout under the headlight.

By reversing it you can face it towards the bumper getting a ram air effect.Ideally you would use a bigger pipe as it does make a difference.

As for the opening in the airbox its about the same size as a 4inch pipe but a triangular shape.
