A Few Quick Questions About Pod Filters And Exhaust Headers

Heyaz

Any way a while ago i bought a pod filter and a adapter for my r32 gts-t type M and have just been looking for the time to make up a cold air intake box for it. But i have been reading and it seems that quite a few people running reasonably stock gear, havent bothered with the air intake box (although a couple of the people are running new turboes, injectors etc.) They just have the pod in the engine bay. So, a pod sucking in warm air, sucks enough in to make it better than the standard panel filter, sucking in cold air? I would prefer not to go to the trouble of making up the intake box for my pod, but i will if its worthwhile (cant afford to buy 1) If any one wants that re-worded just ask, im not so smart :O

Also is it worth putting some custom or aftermarket exhaust headers on it? It has a 3 inch turbo back exhaust, but standard exhaust headers. Am i likely to get less lag or faster spool or moor KW out of em?

Thanks, sorry about the annoying questions but i have looked around and cant really find specific answers to my questions.

you don't have to make a full box for it. just 1 wall to stop the hot air getting to the pod. i have a pod and i have a duct coming up from the intercooler pipe hole (i have a front mount so i have an empty hole) and i'm going to put the factory cold air snorkel back on and just have it sitting on the pod, and just make a single wall up to stop the hot air. that way i will have 2 sources of cold air.

So lets say i had it hooked up like that, coming off the turbo, i would then make a heat shield (out of aluminium) going diagonally from the [wheek arch] to the side of the pod filter to block off rising heat from the engine, and leave the back and front of the pod open, with my standard cold air intake in the same position

right? or wrong

yeah sort of. i have the standard intake, i just have a pod where the airbox was. go here http://www.uniqueautosports.com.au/ and go into parts catalogue, skyline gts-t, engine. then most of the way down the page there is a UAS cold air box. the pod sits in that. basically all you need is the vertical wall.

thanks so far, but another annoying question, what do you mean, have the factory cold air intake sitting on top of my pod? Do you just mean have the factory cold air intake, inside of the partition, facing the pods general direction?

Thanks for your help, so far :ermm:

the yellow line is about where you would put the partition, and the green represnts the top half of the factory airbox and snorkel.

the pod is under the green bit.

i'm having one of those days too. you'd probably want to make the partition out of a heatsheilding material rather than aluminium. any metal will just absorb heat and won't work as well.

you can get stuff for exhaust shops that works really well, but it costs a bit. but if you could get your hands on some high temp plastic, or a square of fibreglass, that would be ideal.

i'm going to make mine out of firbeglass and then go the the wreckers and get an old bonnet lining and put that in there for extra heat protection. if you do make it out of alloy i'd do the same.

r32's dont have a snorkel on top of the airbox like an R33 ...

the cold air intake comes from behind the passenger headlight and comes out of the guard into the airbox..

so yeah, might wanna consider that

So all your saying is if you have a R33 like me just buy the UAS fibreglass cold air box and keep the standard snorkel is that it?? wouldnt that just be pointless??? The air from the snorkel would not reach the pod in the UAS box.

heyaz, i just installed 1 of these things ( yet to add a partition for cold air) into my 32 gts-t and wow. I didnt think it would make any difference but the difference is huge. I dont know if the sensor just inside the intake had a loose wire or what but i added the pod and now i get my turbo spooling at 2800 rpm instead of 3000 rpm and it holds boost almost to 6000rpm at which stage it drops boost, instead of dropping .2 bar the second it hits 5000 rpm.

Makes the car sound a like its got a BOV or something, the pod noise is really damn loud. (not sure if im to keen on it)

thx 4 ur guide mad

nahh, just a pod and made a partition out of 2 peices of aluminium with some heat obsorbing material in between (split pins to hold the 2 pieces of aluminium together) a bit dodgy :unsure:

i wasn't saying buy a UAS one and leave the stock snorkel on. 32 thrasher didn't understand what i meant about a partition. what i'm saying is put a partition up and leave the factory snorkel. if you buy a UAS box you wouldn't use the snorkel unless u cut a hole in the box to feed it into. the problem with the UAS boxes is that if you have a stock cooler or a cooler that uses both stock intersooler pipes, then the box doesn't get very much airflow to it, unless you start cutting holes.

and i didn't know r32s didn't have a snorkel.

      R33 GTR running -9 with no tune

      By Duncan · Posted

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground

      Coolant leak?

      By GTSBoy · Posted

      I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.

      Is it alright to top up with just another green coolant?
