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.

Just get a K&N panel filter for your factory air box.  You won't be sucking in hot engine bay air and they filter a lot better.  Plus you can't get defected for it.

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

    • For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.
    • Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve. 
    • I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.
    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
