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

    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
    • Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣
    • After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
