Hi all,

Am new to the Australian modified car scene. I've tried searching but cant seem to find a clear direct answer and some are in bits all over the internet. So here goes...(with regards to a BNR34)

Which of the modifications below needs an engineering cert? and if so, can we like do all together and then get an engineer to inspect and save $$?

- 19" rims with 255/35 tires

- ganador side mirrors

- carbon trunk

- carbon gt wing 1710mm

- aftermarket tie rods, lower arms, traction and camber rods etc

- strut bars

- sway bar and end links

- gauges mounted on the A pillar

- body kit

- front wide fender (nismo Z tune)

- turbo

- turbo outlet

- front pipe

- high flow cat

- cat back exhaust with jasma cert

- radiator

- intercooler

- coilpack

cheerio guys! :cheers:

Turbo for sure.. what no boost controller, injectors, ECU or Air Flow Meter? These all affect pollution control (EPA laws).

Depending on what state you're in cops will try to defect A pillar gauges "because they are in a crash zone". Yeah not likely if you have a front air bag! and how about taxi's and cop cars (and who's on the road more?). Anyway have the line added to the cert.

Not sure on side mirrors and aftermarket tie rods, lower arms, traction and camber rods etc

rest should be ok.

suspension stuff engineer can sign off on it and over ride the rules but the exhust not under hes power that you have to deal with epa.

thats a relief.... sort of.

are there legal aftermarket exhausts for the BNR34?

Theres nothing that comes with a ADR approved sticker on it if thats what you mean its bascially just up to you to make sure its 90db if you want it to be legal and pass, but doesnt really matter if it is or not because cops will report you on suspicion for exhuast sound as some people have been done on standard exhuast so theres not really a way to be 100 percent bullet proof on epa issues.

Also take into account the stock exhuast is basically the loudest you could have and be legal since it is around the 89db mark.

whats the approximate cost of an Engineering Certificate? If you became a member of a car club would that help alot in getting things approved , i mean if you say the car is used for limited use on road and the mods are for the track etc etc..

I think i read somewhere that we can go get it tested after installing the exhaust where they test for emission and sound rite? if that one pass...surely the cops wouldnt be THAT anal to book u if u have something to show that it was already tested?

also... are they crazy? stock exhaust and still book u?!?!? but i take it that u can contest it right?

  • 2 weeks later...

yeah so according to the ADR..even if they wanna fine u for something ....there has to be proof rite? so if EPA tests prove that its below 90db..then u're ok...rite?

the cops arent judge and executioner wat!

    • I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!
    • I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
    • The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.
    • No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
    • Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.
