Hey guys, i recently got pulled over and copped a defect for my pod filter, so obviously i got that changed instead of my cooler.

but when i go my car tuned, it had the pod filter. Will it affect the performance in any way ??im currently running 14psi and pushing 240kw atw's im also currently got a blitz turnflow cooler so everything fits snug, will that be any difference to a normal cooler have a pod filter or the standard. iv ask a few people and they've given me different answers. is it possible just enclose my pod filter? or does it have to be full standard to be legal??

any help??? cheers

:) LMAO im from Vic, so it wouldnt affect performance whats so ever?? sweet but iv been told that if it is physically untouchable ( the pod filter) then its alright, or have i heard wrong? and is it also illegal to have a ARC air box with the cooler or is it alright?

and +1 on the infomercials LMAO

dude - read the vic section - has all this info.

ARC box + pod, is still a POD. So no.

FMIC & stock airbox.

OR

POD & Stock cooler

Simple and clear choice. Whoever you 'heard' from, knows nothing about the laws.

stock airbox is fine anyway

put it on - DEFECTBEGONE!

Standard airbox is shit and restrictive. Car makes 280rwkw with the custom air intake I got, but with the standard airbox in it's own only made 270rwkw. I'll have my extra 10kw thanks. I got an intake setup that would pass you an EPA or a defect just because it looks like I have an airbox :). If you wanna know it pm me

btw only talking about the standard r33 gtst airbox. Gtr ones are probably better hence you can make decent power with them withou being too restrictive.

What sort of filter were you running, the standard unit or a decent hi flow panel filter?

As someone said above, you need a decent sized turbo to suck more than the standard box can flow.

Just because it looks like an airbox - does not mean it will pass.

It counts as an intake modification if you are no longer using a panel filter and you have a POD. Fact.

You cannot argue the facts of the law unfortunately - regardless of how smart you think you might be.

Just because you might have cut the a$$ out of your factory airbox doesn't mean a lot, if you get EPA'd and try that over with them on a full inspection i'd be surprised to see you get passed.

As for the 10kw - if you can tell the difference, you are a better man than i am. You'll never notice 10kw other racing paper (dyno sheets).

Anyway we were not talking 280rwkw.

We are talking 240rwkw.

I would guess differences would be near on insignifigant using a high quality (read: expensive) panel filter for the topic/discussion at hand.

The thing is i am using a standard r33 airbox with a panel filter. Its whats underneath the filter is the key lol

Ye a big hole with a CAI air feed - almost hidden, been done before, just pray you get the EPA on a good day is all i gotta say as technically its two intake modifications as you have "modified the intake"

Yea correct. My goal was to not get busted in the first place to not have to go to an epa. But yea im aware that its still 2 intake mods but most cops wouldnt look twice.

Yes. I am using pipercross filter ...there are others. I am making 245kw atm - haven't seen my intake pipe sucking shut yet! I'll look at it again when I am getting above the 350kw the poster above is making with the stock airbox.

I got a custom 3 inch stainless intake pipe going to my afm, dont think if you have a turbo with a big compressor housing the standard crappy pipe will do

ok ill think ill stick to a standard air box, but if i were to get a high quality panel filter will it improve the performance and be as good as the pod?

K&N is what i use tried and tested.

You drive a bright orange car... Might as well have a sign saying "look at me" :D

Probably a silly question, but would using a standard airbox & panel filter with changed piping to the turbo be fine?

All I hear are guys being told that changes to the airbox or popping a pod on is not legal if a FMIC is installed.... but what about airbox to turbo piping that still uses the stock AFM?

    • Apologies for the long post, but needed somewhere to lay out the entire timeline of events and actions taken:   I've got an 89 GTR with a R34 RB in it. It's been running great all year, driven probably 500KM in the last month. It's not my daily driver, just a weekend fun car.    Build info: R34 RB26 - HKS 2.7 stroker kit, HKS adjustable cam gears, HKS turbo upgrades, Trust intercooler, R34 factory DENSO 440cc injectors, JUN chipped/tuned R32 ECU. All of this work was performed in Japan back in 2019.    Thursday 10/2/25 - It's a nice day and decided I'll drive it to work, I start it up in the garage and I notice it took a few extra cranks and sounded a bit funny. I figure maybe it was just because it was a pretty chilly morning. I pull it out into the driveway to warm up a bit before leaving. As I leave the driveway, it feels very off and sounds like a misfire. I pull it back in the garage to deal with after work and take the daily to work. I was able to diagnose it as a cylinder 5 misfire with the old spark plug test (unplugging each plug until a sound change with the engine running). I take off the whole ignition system, ignitor, plugs, spark. *Important note, it is still on the R32 ignition system with the separate ignitor system. I test each system with a multi-meter and nothing presents as a smoking gun. I put it all back together and it starts up no issue. I go ahead and order the PRP R35 ignition conversion kit. It should arrive today (10/13/25)   Friday 10/3/25 - Another nice day, car starts up great and drives great all day. Very pleased that everything seems to be OK   Sunday 10/5/25 - Decided I'll take it to play some golf, load up and drive to the course about 25 minutes away. Drives wonderful the whole way there, I pull in the parking lot and the engine completely comes to a stop. I do not recall if it sputtered at all, but just remember all of the sudden the engine was off. I roll it into a parking spot, try to crank it back on and nothing.  It'll crank and crank and not even try to start. End up getting it towed back to my house and push it up into the garage.    Items I have checked: Fuel in the tank Fuel Pump relay Fuel pump fuse  Spark Plugs & gap Coil packs Ignitor    I know the cylinders are getting fuel as the plugs smell like fuel after a start attempt. I tried spraying starter fluid into the manifold and cranking and not even a sputter.    I decided to do the live CAS test (removing the the CAS, ignition on and spinning the CAS stalk to see if the injectors pulse and spark is active). All of the injectors were pulsing and I have spark at the plug. The half-moon end of the CAS did seem very loose, I'm not sure how much play is supposed to be there, but it was more than I expected. There was no in/out play of the shaft, just the tip end that is pinned on had quite a bit of play.    CAS Play video   When I put the CAS back in, I stupidly did not re-time the engine. I know I need to do that tonight, however, I do not think it will start given it seemingly was not the issue. My plan is to do the PRP R35 coil kit and retime the engine at the same time.    I plan on ordering the Haltech Nexus Plug-in ECU once they are available again, but ideally would like to get this sorted before firing the parts cannon at it and potentially adding more variables.    Anything glaring that I am missing here, I'm a bit at a loss?          
    • Get it on a dyno. Get something logging Consult. Run it up and find out what is causing it.
    • Looking for a plenum for rb25 de+t neo  Not looking to push much power maybe 300kw at the wheels, is there much difference in flow for Freddy “Greddy style” compared to original Greddy or options like Proflow or Otaku garage?    I won’t be porting the de Neo head for now as I think it’ll be fine 280-300rwkw but appreciate the help and any experiences anyone has between them and any advice. Thanks  Looking at this plenum for now below 
    • engine wise almost no mods: stock ecu Greddy front mount intercooler Greddy forward facing intake w R33 TB stock fuel system, stock injectors, rail etc. Kakimoto racing hyper 3 inch exhaust system Apexi intake filter New NGK –R BCPRES (.8 gap) plugs  
    • Nice one @Pac - looks like a fair few 1600's there!
