Limits Of The R32 Gtr Stock Airbox

[MrFlex]

Hi Everyone,

I'm just wondering what are the power limits of the 32 gtr airbox. I understand the 34 airbox flows very well. But i recall someone saying to me the 32's dont flow as well. Has anyone actually made above 280rwkw on a standard airbox in a 32? I looked in the rb26 power section and noticed most people use pods. I also saw on a few forums that when upgrading the standard turbos, one of the immediate things to do is to upgrade the intake system, i.e. ditch the airbox.... although this is generally done before anyway....

Please dont post "look at the mines 34" etc, im asking about the 32 - The airboxes are different...

Thanks in advance.

The only reason I changed my airbox to pod filters was to allow the use of larger Air Flow Meters. The Z32 units don't even look like fitting.

For the kind of hp you are talking about the airbox is fine. Just use a good filter eg a K & N.

So when or how would you know your airbox is not sufficient with aftermarket turbos? Would you be hitting a wall in terms of boost ?

simple. if you are on the dyno, do a run. then unbolt the airbox, do another run. if your second run gains say 15+rwkw over your airbox then it's a restriction. if it gains say just 5kw then I would leave it where it is.

Has anyone actually done this on a 32 gtr? What results did you get?

296 RWKW with stock airbox, and k&n.

Now at 340RWKW with stock airbox (no duct), HKS panel filter.

I'd say they flow okay, but I'm still going to open up the intake on the box.

yup pods are dumb and a waste of money, much better sticking with airbox and quality panel filter.

unless you love hearing an annoying turbo whistle everywhere you drive.
