Hey all,

Just got the GTR back from its 100,000km service. All went well except a few things need doing. I had so called K&N pod filters already on the car but the guys who serviced the car said they were not, but infact a K&N copy that cannot be cleaned or something. Anyways, what kind of pod filter should I fit to the GTR? Is it worth spending the extra money on a Japanese brand like HKS or apexi?

I went for a ride in a mates car and he has a HKS pod, and when changing gears it flutters. I WANT THIS SOUND. hehe :rolleyes:

thanks

Boosted_RB26,

Most of the filters that come with the foam type arrangement are shit, the particles end up working there way through the foam and hitting the turbo, this leaves the turbine with pits in it, which can lead to failure.

I have a Blitz SUS filter, they are excellent for airflow but they allow small dust particles in, so in dusty environments are not very good.

The best and cheapest option is to get a redine filter for $25, they give good filtration with no noticable power loss.

If you are into "name brands" then I read the Apexi power intake has a good filtration and good air flow combination compared to the other brands e.g. HKS, Blitz, K&N. Also, it is a dry type, meaning you don't need to re-oil it after cleaning (Autospeed).

Otherwise, just go for a cheap Hurricane air filter from Works. Does the job and for ard the same price as the redline filter you won't lose any sleep over it.

400HP, Damn that makes me a rice boy too. Always new that they filtered for shit, but though that they would make better HP, waste of $400, but it looks cool.

If your not after looks then go for the K&N or Hurricane filters, they are cheap provide good power and filter well.

ok thanks for your input people.

dumb question but are some filters louder than others? the reason i ask is that I went for a ride in an R31 with an RB20det the other day and I think it had a HKS filter. Anyway...it was much much louder than the ones I have now.

Im pretty sure its "works autos" old 31.

BoostedRB26,

In general the filters that don't filter as well will sound louder, so that is not a good thing to go for, mine is hell loud but will only filter things the size of a small child. Go for the hurricane's from Works, they do the job well, plus you'll save heaps of money for something else.

Boosted rb26 i dont think it is the filters that are lounder rather the setup on the car. When i had a pod filter on my car with the stock turbo setup the pod was very loud with all the woosh noises when you back off etc, now with the new big turbo and a different setup there is no noticable annoying noise coming from the filters, i think it is an rb20 thing with loud filters.

Actually I do think the noise is to do with the filter and maybe the engine. A friend with an RB20DET + HKS pod is VERY loud. Then again Franks' car with RB25DET NEO + Apexi is very loud too.

In general all aftermarket filters are loud. When looking at the link I sent before the best for performance and filtration were the K&N and the Apexi.

I have a Trust Airnx filter, and it is one of the foam type filters. It does a good job of keeping out pebbles and small stones, but i'm convinced that it lets anything smaller than that through. It is damn loud, wooshing and fuffling like a mad dog.

I had a K&N on my old car, and it was a much more pleasant sound - deep and tough sounding intake and probably filtered alot better... thinking of changing back to a K&N,

I read somewhere on the UK GTR forum that that test doesn't prove much as there are other variables that weren't taken into consideration. I'll try to find it.

Here it is

It is a long thread, but the Scott guy seems to know.

Silver-Arrowz,

I agree that most tests don't prove much in terms of power, but I do agree that most of the expensive Japanese brands tend to be pretty poor at small particle filtration. I like the look of my Blitz SUS, but if your after value for money then some of the cheap brands will filter much better and not affect power for about $25.

So if your a rice-boy like me, then go the Jap brand, if your not and only concerned about power then go for the cheap pod.

Absolutely.

For the 32R , the gains in a pod filter over a good K+N panel filter are zero unless you pushing big HP and there is some sort of cold air box .

Only thing pod filter gives is the blowoffs are heard which may or may not be a good thing.

Sounded good on mine for about... ohh... 5 minutes then started getting annoying.

Cheers

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
