Pod Filter & Intake Setup...

Hi guys, just wondering, for those who are running non-AFM tuned R34 GTR's, what are most of you running in terms of pod filter setup and intake design? I know that R32 and R33 are different so this is really a thread for R34 GTR only.

There's the APEXi twin power intake kit, then there's the HKS and Trust versions. BUT what options are there available if I wanted to run twin K&N pods? Must the intake pipes be custom fabricated or is there a kit available?

Interested to hear what people have done as I have a D-Jetro and want to upgrade my standard air box.

Cheers,

Ed

Any reason why u wanna run the knn filters? seems apexi got the best rating for airflow/filtration so a simple kit from them would be the best bet.

knn i recall uses a hoseclamp so you could use the standard rubber intake hoses and a piece of alluminuim/stainless to adapt the filter onto; woud be very simple and cheap as knn filters are washable....but then again, so are apexi and you can buy new ones every 2 years or so for 150bsu so they always look new.

as you have a vs2, id say money aint too big an issue, possibly an arc airbox to keep the cops from asking too many questions.

There is not much difference between the R32/R33/R34 GTR intake systems.

As Johnny said APexi are decent pod filters and the kit should come with 2 metal intake pipes to you can bolt on the air pods then bolt on to the AFM's.

One of the reasons I think to run an APexi D-Jetro, is for the GTR's which run massive single turbo conversions and there is no AFM, but I too have seen it on twin turbo setups.

I am not too clear why or what the difference is... Instead of having the 2 AFM's, they are replaced by 2 Map Sensors... Probably so the APexi Power FC can monitor it... Control it too... Maybe.

Looks like they do come with pieces of aluminium/stainless to adapt the pods on.

Any reason for modifying to twin air pods?

The standard R34 GTR air box and filter is good for over 300 kW's.

Hey thanks for your replies guys, appreciate your thoughts.

Johnny:

My tuner is getting better results from K&N's over the APEXi's. I've seen results from comparisons on an R32 GTR and Mazda 6 MPS. The ARC airbox is close to double the price, and is it really worth it for the extra 10hp or so gain vs twin pods? It's not really that stock either, it's big and silver with orange filters haha. But I do appreciate it is a good piece of gear though.

(OO)SKYLINE(OO):

I went wth D-Jetro as the AFM's max out. Yes they run off MAP sensors and yes you can use oiled filters now that the AFM's are bypassed/removed. Also, this means the intake pipe can also be increased in diameter to a custom or off the shelf kit . The APEXi Power intake kit retains the AFM piping so I'm really looking to get rid of them all together as I don't need them there. As for reason in modifying, I'm convinced that twin pods will flow better than the stock air box.

I kept the AFM's installed for that "stock" appearance when I ran a map based ecu in my R33. They arent a performance restriction unless your chasing over 600hp. That opens up the world of other options for AFM based air filters. I was using an aluminium ARC air box. They have nice trumpets inside the box where the MAF sensors bolt onto it.

Right I see.

That explains the point of D-Jetro. Maxing out the AFM's and want even more air = Have a bigger air pod... LOL!

So how big of a pod do you want?

You could take off the AFM piping and just have the pod itself... :P

Yeah, you will get a lot of air in with twin pods... Since you have a Nur, which runs 1.2 Bar = 17.4 Psi, pods will free up the air flow with your test proven.

I guess you can shield off the pods on the side and retain the standard air feed to feed air to the pods.

I want to run standard size'd K&N pod's with the AFM's removed so I have a slightly larger diameter intake but don't know what pipes I need. At this stage I think they'd have to be custom made as I see no kits available from K&N or even a generic type to suit 34GTR. I know APEXi and HKS do the full 'hard piping' kits but they're stupidly overpriced in my opinion (in excess of $750+) - may as well go a full ARC intake box.

Anyway thanks guys, appreciate all your comments. I just wanted to know if anyone else was running K&N pod's and what piping kits were/are available to suit them non-AFM style.

Cheers,

Ed

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
