Hey guys just some advisement... (nice way of asking for a answer) as im from the land with all them sheep you love to tease us about but have secret dirty thoughts about where modifying a car to become illegal means it is not road worth or is a jet plane cable tired to your roof

but im moving to Aus on monday actually and ive been getting aussie car mags so i can learn a few things about whats legal n so forth, and from reading this thread if come up with a few questions since im a dumb sheep slayer as you will be harrasing me about

1. A varex exhaust is illegal i understand that, so what if you have it quite enough to pass with the exhaust on open is it still illegal?? (see where im coming from) as the exhaust is illegal or just having it shut is illegal cause it can be opened (not welded shut)??

2. what the hell is ADR? ive seen in mags where the bonnet is ADR approved so does that make it legal? or does it mean it will pass a form of certification test where all your add ons BOV, Front mount,POD, Injectors blah blah Front facing plenum(for a RB25 as i saw that its illegal to modify you plenum in anyway) can become certified and legal? obviously for a cost, thats what im getting at but im not to sure??

3. where is this place that it gets certified as we have that sort of thing over here like if you change your seats or swap engines you need a cert to show its installed appropriatly and safe is that the same as in aus?

im sorry ive all this has been answered but i got about have way through the thread and skipped a few pages then carried on

1. You'll never get a varex equipped exhaust legal IMO. Muffler only works properly in recirc mode. Begs the question of "why both" when they cost so much :D

2. ADR - Australian Design Rules

3. There are many. Just plug into the VicRoads search - VASS

Any VASS engineer can give approval.

So nismoid does if i got a ADR cert or whatever you call it, and i got pulled up for a noisy exhaust and emissions or what ever i would pass with the extra mods correct? (considering my exhaust is still legal)

from what i know about engineers certificates wont help much, and your exhaust wont be legal because of the cert it will be legal because its below 90db if its not then you will still get done for it.

ur car isnt loud lmao

cos you'd know. take your n/a fail boat outta here brew :D

If you get an engineers cert, and your exhaust is legal - then you can still be "reported" for a "check".

Its not a case of being proven guilty. You are guilty by default in this state.

Hey guys. In short, is a RB25DE+T legal? (If done correctly)

Ie, under section 4, pages 7&8 of:

http://epanote2.epa.vic.gov.au/EPA/Publica...6;FILE/1031.pdf

"the conversion is unconditionally endorsed in writing by the vehicle manufacturer as being ADR compliant"

I doubt Nissan would be interested in writing said letter?

"the type has ADR certification"

Ie. an ADR approved Greddy or whatever kit would fall into this category?

"the converted vehicle is in all respects identical to the production turbocharged/supercharged vehicle"

Which wouldn't be possible as the RB25DE and RB25DET run different internals/heads?

Or, is it the kind of thing that you could get engineered provided you did it properly?

I'm happy to get it engineered or carry a big book around. Lol.

Any help appreciated as I am looking to start getting parts for my conversion. ;)

why bother? either by an RB25DET and drop it in, or since n/a have crappy brakes an shit as far as i know upgrade toa GTS-T given they are cheaper then n/a's in some instances

DE+T is not legal

But then think about it, how would they know?

As long as you use ALL the RB25DET Emission controlls from ECU to AFM's etc, then you wont have a drama.

as above seems like a lot of effort when DET's are readily available to purchase

I want to do the DE+T conversion, personal choice that's all. The idea of a turbo top end, but still keeping the N/A responsiveness and power appeals to me, and this particular car has a sort of sentimental value to me. Why does the majority jump to the conclusion of "engine out" or "new car" whenever there's a whisper of a DE+T? Do they post on holden forums about how everyone should fit a GEN III or buy an SS when they want to supercharge a 6? No...

R31 Nismoid, illegal as in because it's not an identical set-up to the DET? Thanks for the reply btw. ;)

You have a non turbo body - it's just logical to sell and buy a turbo one.

brakes, gearbox and so on - depending on the engineer they might tell you they need to be upgraded... talk to them FIRST to find out.

    • It was cheaper at Trust Kikaku then it was at the dealer with my 15% off. No clue how, but I won't argue. Here's the link if ever you need one. Cheers.  Nissan A/C Climate Control Unit - BNR32 #663111124 – Trust Kikaku (trust-kikaku.myshopify.com)
    • Ah damn. I might grab one myself because mine works most of the time lol 
    • Yes, I mentioned it in my first that I did everything that is mentioned online (Redo dry solders, clean connector between PCB's, etc.) and unfortunately it didn't solve it.  It crapped out again earlier today, so I replaced it. I'll keep the old one around to repair it at some point. 
    • I've looked at some oval stuff but still deciding what material to use for the back half to the muffler.   Yeah I do all my own stuff with ecu setup and have it sorted before generally paying someone (my old work) to do base runs and a few power runs then I'll do anything else myself at track or after review data. It's hard to find  a dyno owner these days that will hire out to random.
    • Injectors are told by the ECU to open for certain amounts of time. If the injector flows more fuel, but the ECU doesn't know this, and is told to open for the same amount of time as the stock, smaller injector, then the larger injector will flow too much fuel/more fuel than the engine/ecu is expecting. You absolutely need an ECU to control injectors. You don't need a tune for a fuel pump (because your fuel pressure should remain the same assuming the regulator works). You don't need a tune for an exhaust (the parameters for fuel and air going into the motor have not changed much) You don't need a tune for an Intercooler (the parameters for fuel and air going into the motor have not changed much, it's just the air is cooler) Yes, forum regulars, I know that you really should get a tune for an Exhaust, and Intercooler. These *will* affect the tune, but the stock tune does have some leniency to it with stock AFM and Injectors. Intercooler and Exhaust will fit within this wiggle room. So will running a boost tee to about 10psi, which is a very old way of increasing boost which is not worth doing in 2024. The ECU is vital. It runs the whole show. Most people change injectors and ECU at the same time for this reason. Some people load base maps on some ECU's that have ballpark figures for injector sizing. Sometimes injector manufacturers are really great and tell you what parameters to input into your ECU, which is something you can do with your new shiny ECU. For a beginner, this may enable you to drive to the tuner to have an expert do the rest. Otherwise, you're installing injectors and ECU at home, and paying for a tow to a dyno. Or, you take the car to a workshop (be happy to travel across Melb for the right shop) and someone who knows RB will be able to source/provide/install injectors and tune the car at the same time if they have a dyno or access to a dyno. The reason so many people DIY things here is because finding said workshop is hard, expensive, potentially getting things wrong with miscommunication/other.
