i dont have dyno info,

but dont put on a pod without a heat shield, you will definately lose power if its judt ditting there in the hot engine bay.

stock airbox with panel filter and cold air pickup pipe is usually the most effective value for money

  • 1 year later...
is there a difference b/n the gtst and the gtr stock box? in the r33 especially.

no. I run over 250rwkw.

Wack in a hi-flow panel filter and u will be set. I was convinced that unless u have a sealed box...ur just wasting time. Mine was loud and annoying...also a cop magent...stock box is quiet...and stealth.

I use a Trust Panel filter...works a treat. Dunno how much they cost but a K&N would also be fine.

Although I'm designing a new snorkel for the stock box...we be finished in a few weeks...will post pics. But its runnign fine as is right now.

Hi there,

I did it on the dyno and absolutely NO difference. 254 rwkw power runs - stock airbox with K&N flat panel filter one run, then we removed the top of the airbox and flat panel filter so NO RESTRICTION WHATSOEVER and the same 254 rwkw power output - both runs done with the BONNET UP so no temp differences either.

The turbo is 2835pros kit so has fabricated aluminium turbo intake pipe which mates up with the stock airbox.

Around these power levels pods are a waste of time/money unless you like to hear the turbo/blow off valve - and in a lot of cases poeple will see a decrease in power due to the engine sucking hotter air.

Cheers

it would be ok having the pod sitting behind the front bar low to the ground? thats what i got and it's barely even dirty after 1 year, then again i never travel on dirt/gravel/sand roads, the only thing i do is avoid puddles or where theres to much water build up on the road. Sometimes the sounds gets very annoying and I wish i still had my airbox

it would be even better having the open top type filters sticking low and just behind one of your front bar slots. In a S2 R33 with front bar (stock) after doing FMIC it is possible.

people have had issues with direct mount pods like this...too much air at higher speeds. They needed to baffel it to stop issues at 80+ kmph.

That being said..the gain ur gonna get..hmm not too much...stick with stock, get a decent filter, protect ur engine from crap and avoid another defect, oh an piss of they stupid whoosh sound..lol.

thats good to hear. especially as i've just ordered a apexi panel through kudos motorsports:P .

always wondered if its possible to do a CAI on the stock box. is this what your trying to achieve chris? any one else done this? pics would indeed be helpful :no:

andz 69: i guess it dependes on how much power they're running (which i havent a clue about). we are talking performance benefits at power levels of bout 200-300kws though

I pulled off the pods and got a hold of an airbox and k&n filter simply because,

it's my daily driver (don't want to risk defect),

Pods are illegal in NSW and can't be engineered unless fully enclosed(too much stuffing around),

heatsoak in traffic.

personally I'm not convinced of the pod style installs where they just sit in the bay. I have done this to a few cars an recently just returned them to stock which better filters and intake pipes.

As long as an air filter and box is properly sized for an application, the lost airflow will be very minimal. I haves een some1 do actual testing but cant find the link.

If ur worried build a new lid for ur stock box and feed more air into it with a new snorkel...looks stock. In fact thats what I'm doing.

My 2 cents

1. Air Box fanboy here....just look at the mines GTR

2. Pods are really only useful IMO when there isnt room for an airbox or it isnt suitable for plumbing.

3. I fail to see how a pod on a intercooled car will effect the inlet temps inside the cylinders....maybe a poofteenth of a degree once its passed through the intercooler? I can understand sucking in 15 degree air compared to 50 degree air will differentiate as the intercooler can only do so much in the amount of time it has an air molecule going through it, but with the forward acceleration of the car colder air from infront of the car should go into the pod, and I doubt that a majority of the hot air from the engine bay will get into the pod as it will most likely go out the top of the engine bay and over your window / into your vents etc....

the air that actually hits parts of the motor etc will bounce proportionally to the parts it hits.....

Therefore I fail to see air that is being slammed into the front of a vehicle travelling at XXX km/h when it has little velocity before it hits the car will have less of a chance to get into your air intake than the air that is rushing to the back of your engine bay and out of any gap it can find (as mentioned between ur bonnet etc)

my 2 cents of keyboard warrioring at 1.30am :no:

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
