hey guys does anyone know if engineers can engineer Filters if i had made a aluminium box around it ?? Because the RTA Is getting really tough on these boxes around them .. A workshop was telling he couldnt pass it, or is he just having me on

any ideas guys ??

thanx..

Pretty sure they can pass it. You may need an emissions test done however. I think the laws/ADR's for pod filters and such are regarding changes to emissions if intake is modified, thus you may need an emissions test.

From top of my head; you're allowed ONE intake modification legally... else needs to be engineered or something? Which is modifications including putting a FMIC on, filter, anything...

Call up any certified engineer and ask if they'll do it/criteria is your best bet. They always change the rules.

Ok thats kewl guys, I have already cleared my RTA Defect With a blue slip..

Trying to get my EPA One cleared Now. Doing a emissions tune got that under control But then its Got Rectify Noise for Filters in which case i have built the aluminium box for filters to try and seal off all noise .... I do have engineers papers for this box. Why i am very concerned about this is i cannot put the standard box back on because i am running a power FC D jetro which runs Without AFM'S So in this case if they still try and stuff me up what can i do there , The rta is not clearing my EPA Defects but there is a list of too workshops in sydney....?? I did speak to the engineer and he said it will be fine but im not too sure.. Any thoughts guys ?

thanx for all the help..

If the car's tuned with aftermarket intake, etc. and nothing's been modded since the emissions tune... then car should pass emissions, which is the main concern - as this be where major fines can occur.

EPA are seperate body, hence RTA cannot clear business with them, but can take your car off road because of them...

Pretty sure emissions tests aren't all that accurate either :D

If the only issue is noise from filters, maybe you could try putting a smaller one on? and block up your box a bit so that less air can pass through - if induction noise was the issue. Stock intakes are restricted and don't make alot of noise, thus restricting it should shut it up a bit. ;)

The issue isnt actually the noise from the filter box .. its the actual box , if you see the box i have put on now there are no gaps wat so ever its a perfect box not some dodgy back yard box...

I dunno i guess ill take it and see if it passes if not ill have to work something out... :D

The rta is not clearing my EPA Defects but there is a list of too workshops in sydney....??

the 2 workshops....

1 at Granville and another at Campbelltown?

I didnt go to Campbelltown so I cant make a comment about them.....

However, I did go to the guy at Granville and from my experience, he's too strict and right down to the letter of the law.

I have no doubt he would have still failed me if my GTR exhaust was 91db!! Luckily, the car came in at 88.6 (but he still yelled out 89.6!!) I didnt give a shit by then as the car finally passed (afer 3 tries at it)

cheers

Yeah jeff thanx for that,

The guy at granville is a bit of a prick i did go there didnt get a test though as i havent done a emissions test as yet.My noise test will be fine though i do have the standard exsaust on there.. i did indeed call the guy at cambeltown i did have a chat to him Mainly about My Air filter Aluminium Box which i had somebody build for me. He told me its not up to us to decide the EPA office will decide But he was being negative about it, i do have an engineers Report for the Box but some people are saying even thats no good these days ( I READ A POST ABO BOB MADE ABOUT THE DECC I READ IT ALL :-( ).... . My question is if i do need to put the standard Air box on how will i do it . I am Running APEXI D-JETRO Which runs Without Air Flow metres ? and the standard box runs with air flow metres ? Anybody have any ideas on this ? THANX..

As you said, it's a problem to make it fit. The afm itself shouldnt be the issue.

Your box should have something to let it breathe.

I'm not quite understanding what the EPA's problem is/what you've got to pass?

If the noise test is fine; is it an emissions test? if so, that's exhaust emissions - nothing to do with your intake. and if your intake is modified and cleared by an engineer, they shouldnt have a leg to stand on against you.

My EPA Defect

Rectify Increased induction noise ( AIR FILTER )

Ensure all Emission Control Equipment Conforms with Manufacturers Specifications

Large Intercooler Fitted

Remove Variable Boost controller

Waste Gate Actuator Arms Welded , Remove Welds

These idiots got no Idea, My intercooler is actually Standard Size as a R32 GTR But its an aftermarket Firstly , My Mechanic told me The waste Gate Arms arnt welded that they dont know wats going on ( EPA ) , Boost controllers gone to get it passed . Emissions Tuning i am doing this week to get it passed.

Emission test gets done at the RTA , Rest of the stuff gets cleared at a authorised workshop but there pricks. i Rang up one of them and told them i had built a filter box to get it passed which had been engineered and he told me it may not be good enough the DECC Is getting really tough.. When you hear stuff like this you get frustrated Knowing you paid a engineer to pass it and you dont know yourself if its going to help you at all....

. the engineer yes has passed it

This is what he wrote : Aftermarket Front-Mounted Intercooler and Ducting

Aftermarket Intake Plenum and Throttle Body

A K & N Air Pod Filter Enclosed In a suitably Selected Air Box , With Cold Air Intake

Shouldnt this be good enough ... Thanx for all your help george..

i was talking to the guy at granville about coilovers and other mods to be done on my car and if they will pass....

he said to me that if im unsure, get an engineer's certificate so i dont have any probs.

so i dunno, with that, i reckon if i had engineer's certificate for my mods, he'll take that into account and pass me?

if you have a lot of time in your hands before the due date, why not get it tested and see if you fail or pass before spending more money getting things changed just for the test?

Thats my plan only problem is ive run out of time ehehe.... but i will ring up the DECC TO Get a Extension... By the way that guy in Granvile is a tool hes got no idea... he had no clue with my car all he said is this wont pass this wont pass.. E.G Ive got a aftermarket Plenum hes like na that wont pass I do have it engineered Mabye because it looked very shinny he thought of it as a hazard.. Like i said HE HAD NO IDEA THAT GUY..... I Called up the guy in cambeltown he sounded like he knew what was going on... Hope for the best...

Did you have you Standard Air box when you done the Test ??

If there's a specific induction noise level, all they can do is test it and tell you if yours is louder. If yours is restricted enough, shouldnt be louder. Maybe try a deadner/rubber/foam to line the aluminium with, as metal makes more noise than rubber, etc ;) - and it's removable.

larger cooler and filter - as said before, i think the rule is only 1 intake mod; and you have 2 engineered. Engineered means that it's certified with ADR, so they can't say shit, all they can do is double check it unfortunately.

same with boost controller and waste gate, etc. If it's all certified with ADR by an engineer, the EPA can check it. If it doesn't pass, engineer is liable - unless you changed it after the certificate.

You're not permitted to adjust how the engine is running from inside the cabin - part of ADR. Hence adjustable boost controller is not allowed.

If you messed with any emissions control systems when you modded the car... big whoopse. :dry:

Other than that, just get it tested and hope for the best :D

If they say anything, talk it over with engineer or mechanic, and post it up here, and people see what can do about it.

I have a 4" pipe runnign from an exposed filter to a reducer to my turbo; got defected but they didnt even notice it :D

Had to get a blue slip to clear all the other b/s defects, and they didnt notice it either :( -but i wasnt dealing with the EPA....

'luck.

The guy at granville told me if i were to put my custom air box in for the test when i did mine, it would have to be engineered before hand, so if its already engineered then there shouldnt be a problem as its been previously approved to clear EPA standards?

A workshop won't be able to pass it unless they are an Engineering Signatory (see RTA site for a list).

I went through this when I had mine engineered. Some engineers just won't pass pods at all,

probably because administering a drive-by noise test is harder than looking over the car then collecting $500.

Who'd have thought?

Pods can certainly be engineered (mine is). They need to be enclosed; and they need to not change the

emissions of the vehicle to beyond the legal limits. Unless there's something wrong with your filter the

tailpipe emissions should not change; but you will find that they are noisier (this is what most

people get knocked back on). Basically, you need to be able to pass a drive-by noise test.

Keep ringing around the engineers on the RTA list till you find one that will tell you how to

pass the test; then do what they say and get your car certified... you will definitely find more than one.

Regards,

Saliya

    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
