Pod Filter Help

[Aznbongsta]

Hi All. i have a R34 RB25DE NEO and i want to install a pod filter but i got couple of questions.

1. My car is pretty much stock with a Fujitsubo exhaust system (legalis-R), will i gain power at all?

2. What sizes does Pod filter come in? I know that having one is illegal, so i was wondering if i can get one that can fit inside my original airbox? Has anyone done this?

3. If pod filter does come in difference size, will performance decrease if the pod filter is smaller?

4. If im hiding the pod filter in the airbox, does it defeat the purpose of having one over a hi-flow panel filter? ( i sort of want a bit of sound from the pod filter)

I guess if all doesnt work out, i might just go for a hi-flow panel filter.

Any help will be thankful

1). Umm, to gain power you need a heat shield and cold air intake, the exhaust wouldnt do anything the cat and extractors are all that needs to be done to NA's if you want value.

2). All range in sizes (length) Apexi are stubby if your after a small one. If your a P' plater its "illegal" but i have had every cop that is not a highway patrol fine with it. Reason being NSW ask for the pod filter to be enclosed in a heat shield too make it legal for street use. The cops see it like that and are fine but the highway patrol just say take it off and then drive away. Yes people do put pod filter in there stock airboxes.

3). No, not necessarily. you could have filter paper wrapped around your intake hole and it would still change how much air is being taken in.

4). Yes, if you make yourself a heatshield and cold air intake with the pod in it and had the stock airbox and highflow panel you would be looking at the same setup for a NA. There isn't enough induction to create an actual strain on how much air flows through the filter on the NA. Thats why turbos and pod filters will atleast make there difference, you wont get induction sounds for it. If my foot is flat to the floor and i get to 5000rpm i can hear a sucking that sounds pretty weak. Id compare it to like 10% the induction volume of a turbo

To be honest, it will have no performance difference. Its up to you if you like the stock look or a pod filter look.

K&N Panel in the box would be your best bet. That's what I done till I had my conversion done, and even then there's panel filters that still flow very well for that application.

As Andrew said, they really need to be shielded from the heat soak in the engine bay. Stick with a high flow panel in the box and it will go unnonticed and you won't compromise the small gains to be had.

Hey Thanks for the tip. I notice that you turbo your DE. How much does that roughly set you back? im thinking of doing that after i get off my p's.

A little or a lot.

I used a misx of 2nd hand and new parts.. biggest killer in costs is the labour and tuning! I've lost track of costs now, they always get added to, whether its an EBC and tune, rebuilding a half dead gearbox, or just throwing in some gauges to see how hot my oil is actually getting and that I probably should consider the cost of an oil cooler in summer. really allow between 3k-5k.

Also consider that the brakes on an R34 25GT Sedan (not the GTV) are piss poor. 280mm front discs and 265mm rear discs with 2 and 1 pot calipers is really a joke so factor in a brake upgrade to something like R33 GTSt brakes, and custom lines to suit.

You'd be best getting sorting out things like suspension, sway bars, tyres, brakes etc.. before throwin on a turbo. if you've already done those things, then start saving and way up the balance between an engine swap and a conversion.
