Vehicle Engineers reports, 4WD Modification rules, whats allowed, what not...

NSW. A few years back I engineered my GQ with 6" lift & 35's. Engineer said it would be a good idea to engineer the turbo setup aswel as GQ TD42 never came from factory with a turbo. Cost me an xtra $100 but same deal, had to fit a muffler to quieten it down.

I think you will find that you will get different info from different engineers/certifiers as from what I can work out it's a bit of a grey area. My 2 local engineers wouldn't engineer a Patrol over 3" lift with 35's. I know they both work together & they are bios! He passed a landy with 35's & a jeep with 37's so I searched further a field & found quite a few who would engineer it but price was way over the top. then I found my current engineer, strict but good on price. Didn't bother me as I wanted it 100% legal for insurance purposes & safety.

Unless you pay to get him to engineer the other mods.

Yep.. get the car how you want it and then get it passed for the lot..
Wish I was in Adelaide.. would make dealing with the sa boys much easier..

Oh & because of the heavy suspension components, I had to lower the seating capacity from 7 to 5 because of the new tare weight. He didn't charge me any more than what he quoted but I know a lot of engineers do.

Wow! I was quoted $2400 just for the suspension by one mob? Wouldn't touch 35's.

Seems to be a trend in NSW being much cheaper.... can we cross the border to get this work done or does it have to be engineered in your state.

Well that's one point I'm very interested in finding out..
I would so no due to each state having different rules and regs, and each state having there own listed engineers..
But then how do we go for legalities when driving our "legal" rigs into other states??
I'm planning on calling back the bloke I talked to last year and having a chat..
If price is not extreme I'm going to eventually get it done with a 3" and 35's.
(That is illegal here is south aus)

So all those blokes who get write ups in the magazines with their rego numbers in photos will be easy game for authorities.
Even with numbers covered, I bet publishers would roll over with info if pressure was applied.

Might be possible, but I'm guessing the inspector would need 2 know the rules for your state.

I found this from an article "MOTORING ENTHUSIASTS’ CONFERENCE EASTERN CREEK"

29. Why won’t NSW recognise and accept engineering certificates issued by other Australian registration authorities?

Under the Commonwealth Mutual Recognition Act 1992 RMS can only accept certificates issued in
another State or Territory if the certificate was issued in accordance with legislation that is reasonably
equivalent to the NSW legislation.

NSW is currently reviewing the potential for certificates from other state s and territories to be recognised by NSW where appropriate.

a few years back if you removed your rear seats to do a lap from Melb it was illegal in Sth Aust
They may have relaxed the rules knowing this mod was only temporary ,
but it reduced your patrol to a two seater.
Question would fitting drawers need a cert as youre reducing the factory seating capacity.
Only for insurance purposes

Still an issue in majority of states... I believe QLD is red hot on the same issue

Only 2 months ago had some seating capacity changes blue plated here in WA after last row seats removed.
When the seats go back in the seating capacity mod plate gets changed back.

Vehicle is illegal otherwise
