Hi all,

Givent the amount of airbox vs pod threads on here I thought I might share my experience.

My car is no power house, it is a S2 r33 gts-t with a turbo back exhaust, r34 gt-t intercooler and until now a K&N pod.

The reason I love this car is its responsiveness which is why I have kept the mods to a minimum. I enjoy its peaky style compared to my old pushrod v8.

Now I have finally sourced an airbox, bought myself a BMC filter and installed it. I also made a scoop which ducts air from behind the grill into the snorkle (figured it might be worth a few kw at road speed?)

Now I have noticed lately as the weather has warmed up that my car has become less responsive when leaving the lights (fast or slow) no doubt due to the fact that the pod/engine bay had heat soaked while sitting still. I also noticed when cruising slowly that if you put your foot down (rolling start) that it was not performing that well and even hesitated sometimes.

So I have finally sourced all these parts and put them in, what a difference!!

The car is sooooo much more responsive now, I dont think it makes any more peak power but in any circumstance when you accelerate, standing still or in gear its better! the car also dosnt hesitate anymore.

This was probably the best 'mod' I have done to the car and will be a great thing next time/if I get pulled over :D

Anyone 'deciding' which way to go with the pod vs airbox debate should read this carefully before selling their airbox I think :)

to make sure I wasnt making the improvemtn up in my head I gave dad the keys (he is a car nut himself) and even leaving the court he noticed a difference, once I told him what I had done he was quite shocked it was so difference from just that mod.

airbox and high flow filter FTW!

Anything to reduce heatsoak is going to be a win. I still have my shitty foam mushroom pod filter on my 33, but have purchased a fibreglass cold air box to enclose it off a fellow SAU member here in Canberra. He had also lined the inside of it with that heat reflective shiny foam shit to help....and it definitely makes a difference. My pod used to feel hot to the touch after driving before, and now it's barely warm.

ill get some. basically just some folded aluminium which mounts with the same screws that hold the snorkle to the rad support. it bents down with a curve behind the grill so it scoops incomming air up into the snorkle. dont know how much it helps but it certainly cant hurt!

It's not the pod's fault that you just stuck it in a hot engine bay! biggrin.gif

Most people who install pod filters fit some kind of heat sheild and/or cold air intake to work around this issue.

In saying that though I've heard that the stock airbox with a good quality filter is good for up to 300rwkw and is much less bother with the cops!

Personally I love the sound of the intake with the pod filter (I am running an Apexi pod in a fully enclosed UAS aluminium cold air intake box)

+1 ^

I made my own heatshield/box out of 5mm aluminium and lined the inside with insulation material; there is no noticeable difference between driving when it's cold or driving when it's hot. Obviously when ambient air temperatures get hot enough you notice a bit of reduced throttle response, but panel filters would feel the same effect.

It's well known that pod filters will be less effective if they are exposed to the heat from the engine bay. Simply box it, problem solved.

    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • 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
