Would RB25DET and RB26DETT need to pass euro 4 or only the emissions standards of the time they were produced or the R32 was made?

my RB30 is engineered and emissions legal according to NSW and ACT requirements (car is from 94) and the emissions components of the engine dont change from the RB25, so its required to meet the 1994 emissions levels which are far more relaxed than euro 3 & 4.

i am not sure if the VIC system treats them differently.

The IM240 testing regime has been ditched for about 4 months now, they are using the 5 gas test to pass cars now.

If anyone has Zoom mag issue 146 (with the orange 764hp CA18 datto on the cover), read my 2 page article on pg 96/97 about it...

yer i know, just saying.

yer i know, just saying.

thank fk it's gone hey!

IM240 was a prime example of the government trying to be smart, and failing.

"Oh yeah I'll just take my AWD car to KEC to get the test done, wait! ... They don't have an AWD dyno..."

OK so i spent a few hours reading today... And have come to the follow conclusions thus far:

ALL ECU’s must be tested for compliance, LA2 clearly states this is a requirement, so its full ADR.

You have two distinct elements of engineering to deal with as a part of LA2.

1. The replacement motor itself.

2. Emission testing the RB30DET with all the aftermarket parts. It must go via the LT3 & LT4 as a part of LA2

Now as it stands. Part 1 - “LA2” is nothing more than a simple VASS Cert in Victoria. Costing around $600 and then you are done.

Piece of cake really, and exactly how I had my RB26 registered into the GTSR.

Part 2 of LA2 is the absolute mongrel, paperwork minefield and overall waste of time.

You need to get the full ADR testing, and then the same for the exhaust. That is a massive amount of time and money.

Once you do that, and only once you do that – are you fully engineered and totally safe from defects.

OR you can do just Part 1, just like everyone else. As it’s just a “VASS”.

Issue is you can’t modify and as soon as you do, it ends up with the EPA getting all funky on you time and time again.

Given you want to use a heap of obviously mods, you will get reamed, and they will probably take photo’s of your engine bay.

If you use a 26 head, you’ll basically be undetectable with only ECU/Injectors requiring a swap…

And that’s IF they pick it… As there are ways around that of course.

I'll do some more reading on ALL the ADR stuff over the next 2-3 weeks, it'll take me a while given I've got functions/booze sessions almost everyday from now till NYD :D

thanks nismoid. Yeah the exhaust noise and emissions test would be too hard.

I think after all this i've decided to change pathways. go with r32 gts-t and put rb26dett in. as you said low mount gt2860's will be stealth... then it's only vass ticket i'll need (if a bit sneaky)

damn vicroads and the fun-police

I know you're leaning towards a 26 now but just going back to your original proposed setup, I'm not sure a plazmaman plenum on a 25/30 will fit under the bonnet.. there's not a lot of room and the plazmaman plenum retains the factory runners (it bolts on top of the runners). Better bet is to go with a GReddy plenum, I couldn't find one for my setup (R32 RB25DE head, so RB20 style) so made up a custom plenum with GTR chamber welded to RB20 runners.

he wants to avoid legal issues.

that item is stand out like dogs balls obvious.

a good condition 26. -9 turbos, 300rwkw easily... and virtually defect free vs a similar result, and more headache then its worth.

if you've never lived/dealt with the Vic rules, police and EPA then you rarely appreciate just how bad it is.

i was defected not 6 weeks ago for semi slicks... which were totally legal.

end of the day the Vic police do what they want, thanks to Steve Bracks and his bullshit 'hoon' campaigns.

I realise this and appreciate that is why he is now leaning towards the 26.

I was addressing the plazmaman plenum on an RB30DET purely from a spacial standpoint.

At the end of the day, you can still get stickered for semi-slicks here in WA, you can get stickered for anything if the cops don't understand it.

Hell, when my 32 was defected (just after I dropped the 3L in and hadn't legalised it yet), one of the items on the list was for my STOCK BOV!

yeah but you can get legal, and then take them to court.

we can't get legal, so you'll never win.

It still won't stop an officer on the side of the road from putting another defect notice on it. Even with permits, the cops only need to suspect that something has changed to send you back to the pits.

But I'm not some teenage little shit so I don't get hassled and rarely get looked :)

P.S. move to WA where RB30DET's are easy to legalise :D

Not a teenager either...

However when i was a teenager i used to drive my datsun 1200 ute with custom made turbo setup (T25G) daily around bendigo ("the hoon capital") and never once got pulled over for it. Even with p's up!!!

Goes to show it's not what you drive but how you drive it and when you drive it. I drove it to and from work everyday for 12months and never got pulled over, while my mates would go out in their "sick vn bro" on a saturday night and cut laps and sure as eggs get canaried!

Anyway this is all way off topic now. Quite a bit of good info in here though

There is a lot of info in the EPA / Roadworthy thread in the Vic Section too mate.

I've tried to answer as much as I can over the years as I've had EPA's, Canaries, trips to court (to challenge the defects)... You name it (and im 28 now).

Also had at length chats to the EPA officers on many occasions about various issues as well as a few VASS Engineers.

It's interesting the things they will tell you if you aren't the typical dumb ass-hat that comes in there and wants to argue with them or tell you the sorry story of how the officer EPA'd you lol :)

Consensus seems to be 300rwkw is the point where you need to be looking for a new exhaust manifold. Don't get a cheap Stainless one - get a 6boost or a Sinco customs:

Nice manifold! Mine was one of Mikes first merged ones and the car he did half his testing on. Hes probably told you the overboost story, and yeah that was my thing not holding boost.

Was thinking about moving to Aussie due to better job opportunities but think i might stay in NZ. My 350kw car is perfectly legal on the roads with big wastegate, turbo etc. Its a shame really that you guys get put through the ringer for wanting to modify a car.

    • Did this end up working? Did you take some pictures?
    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
