Hey guys,

Just been reading up through the epa guide lines and it states that no modified or aftermarket plenums are permited... So this means anyone with the greddy style plenum will have issues?

Just wanted to confirm with everyone. Anyone been done for it?

Cheers in advance guys. :-)

i think the answer to your question is yes and yes.

although i thought it came under the 1 intake modification rule, but based on what your saying thats not the case. if it says illegal then its illegal.

If that's what is in the guidelines, then you've answered your own question.

As to whether anyone has been picked up, that simply comes down to luck.

Some people probably have, some probably haven't... That's not to say it wont happen tomorrow.

and it would depend how it looks too

if its all grey dark and oem looking and looks standard you might be ok

if its got HKS and greddy plastered all over it with shiny parts and nice blue coloured joiners etc

then its likely to get more noticed

Get it engineered then its all legal. For the intake plenum you'd just have to make sure the tune is correct, as GTRR34 says because the AF is different.

Do all your intake mods at once before doing the engineers though, as it will be expensive.

not to mention that with all aftermarket ecu's being illegal, you therefore can't "make sure the tune is correct"

(even if the tune is better for the environment than stock) go nanny state!

my case.

f**kn stupid i reckon.

but im told that a stand alone ECU which is locked after a tune can be engineered.

its only PBacks that cant be eng'd.

or was I being trolled

I had a Greddy copy on my 180, the boys at EPA still passed the car, guess they like me

Aftermarket ECU's can be legal providing they pass a special emissions test (which i was told by Lou at EPA is about 3g and if you fail there goes your 3g) and it must be locked.

Well technically you can pass with remap since you cannot tell from visually checking but the problem is passing the a/f tesf they do, so even if you did get an ecu engineereed but it failed the emissions test it still doesn' t help.

And how do you lock it? a factory ecu is considered locked but is it really locked?

Unless im mistaken you first need to pass the emissions test before you can get it engineered.........

Once you pass the ADR emissions testing aka: "3k if you fail, tough. You have to pay it again".

Victoria, fail state.

you know what is really stupid..

Adding an aftermarket plenum and nothing else would have zero affect on emmissions and would actually make the car slower yet some how its deemed bad enough to consider it defectable..

f**kin victoria

    • I mean it's a bit late to say "This won't have any tangible effect and it is not worth spending more than about three seconds on it, please just enjoy the car" But I said it anyway. Does the pod actually get any airflow in that position behind a bumper like that?
    • Hey guys - apologies for digging this up. Has this website been shutdown or is the outage temporary?
    • So, went shopping at Just Jap for things that might work for the intake  After some trial fitting there I ended up with a 3" x 45° silicone bend, a 3" x 300mm alloy straight, and a humped joiner, some minor trimming will be required to shorten some of the stuff, but nothing that is beyond my "ham fisted" skills The guy at Just Jap was most helpful as we had all sorts of joiners,  bends and stuff out trial fitting  Laying it out above the stuff in there it seems everything will fit nicely, and looking at it, it is probably the way I should have been looking at doing it from the beginning, probably..... In the end it is a front bar off job anyway to remove the original stuff behind the front bar that is taking up the required realestate needed, so maybe a Thursday or Friday job And because I'm a hopeless consumer, I grabbed some new steel wheel nuts, the current ones are a spline drive type with a "security" socket, that somehow someone keeps misplacing, the new ones are a basic black steel 17mm hex socket In other news: I just did my "final" tax return, I am now officially a old retired veteran pensioner, and I'm milking the system for all it's worth,  life is good
    • I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!  
    • Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out
