Sorry I've come in a bit late in this thread, my advice could have been more timely...

Anything can be registerd, and nothing is "illegal". It is not against criminal law to drive a rotary powered bug. It will not however comply to ADRs as a bug...

In NSW you will need to get it registered as an ICV, or individually constructed vehicle. This involves stringent engineering tests, stuff like tortional rigidity and the like, as well as some pretty easy 1st year mech eng calculations.

Make a booking with an automotive engineer, talk through your plans with him (costs less than a dentist!) and then make your decisions. It'll be the best money you'll ever spend on the project.

ILLEGAL is a very strong word...

They stipulate that i need an engineers report, including brake fade tests, lane change manouver, Dyno results for motor, and ridigity test. I've got an engineer in Adelaide who is happy to help me achieve this. Brakes continue to be the biggest black area, I've got type 3 all around at the moment, but the falcon rear disk set up sounds like the go.
Engine trandplants is one of the reasons why I am developing/manufacturing a big ventilated front brake kit for Beetles. See my thread 'big brakes for Beetles' for more info and some pics of what I am doing.
Slightly off-topic... I don't "get" the rigidity test...?

No, no, no.. it doesn't have to be an ICV! Just an engine transplant with engineering certification. But yes yes yes, ask lots of questions, buy a copy of the Code of Practice for Light Vehilce Modifications for your state and talk to an engineer before you begin work

That's different - it's not an ADR 37 compatible Australian market engine. Think HQ with a VP V6 in it... or likewise

A VN... how the F* did you demonstrate compliance with current crash protection ADRs for ICV?! Or did you retro-fit VS airbags?

Herbie Runs a standard 12A at the moment,
Although I have had dramas getting the 43 year old accelerator pedal mecanism to reach full throttle, or even close, it is by far a big improvement over the 1200 I took out, {That possibly wasnt getting full throtle either.}

Its great to see the look on peoples faces when they see Herbie doing over 160 klms, and I guess they think the expression on my face is equally amusing when they pull up at the lights and I just cant.

By the way, that only happened twice when I first did the conversion, since then I learned to settle down or die.

Mine is perfectly legal in Queensland, and I would expect also in N.S.W.
but a 13b is too big according to the rules and a turbo on either would also break the cc/weight restictions,
However you can restamp a 13b to say 10A and then Turbo Charge that baby.:thumb
But you would want to sort the brakes and maybe fing a serious gearbox probably from a porsche, On my next trip over to the states I think I will buy a 911 porsche wreck and bring it home, I've seen plenty over there in the wrecking yards, they pile them up with the Mercedes, its a totally different attitude to european sports cars over there.
I can then proceed to graft the running gear under the bug/Kombie.

Definately go to ZENJOE's website, if for nothing more than inspiration.
My kitt is a sherman engineering kit and is a real early one too, it uses the rotary starter motor , Flywheel and clutch. which gives me a strong cheap clutch setup but because it moves the engine a few inches back I cant run an electronic distributor under the standard decklid as its too tall and fouls, so I am running a points distributor, I will set up a crank angle sensor oneday but its a low priority at this point. Ironing out the cooling system is my main challenge at the moment, I think I have a tiny pihole leak that is reaking havoc.
If you are putting the setup into an off road bug you wont have these sort of troubles.
Email me at "info at anthonyvoevodin dot com" <- {I do that to avoid bots sending me spam.} if you have any questions, I may be able to help.
If the engine your friend sells you is only 20000klms old and is built properly you should be fine, however same as anything, an old motor wont last as long as a new motor and rotarys have a habit of running fine right up till their final day and then they die, no major indication of their wearyness, but its all about fresh motors and treat them like you are not trying to rev them to oblivion, despite popular theory they dont really like it, and wont put up with it forever.
A turbo rotary doesnt need to rev that hard to create all the power you can get to the ground and for so many reasons are a better idea all round.
Make sure its tuned properly so it doesn't lean out, They are quite intollerant of that, and then just set up water/alcohol injection and raise you boost as high as you turbo can feed it and then try to hold on tight.

Lots of fun.

It wasn't actually me who built it, a friend who's been in the game for a few years, although I did a bit of work on it and it's hell dodgee.

I do know it runs BBQ juice to stay emissions compliant, and from what I can gather re: the rest of the certification, sometimes it's not what you know but who you know.

Sounds like that baby might just rip itself clean off its mounts and out the side of the floppy VN!! woohoo :P

Why not just strap a jet engine to its lid! its been done before with great effect, or is that impact!! :duh

Hmmm no offence, but it's sh*t like that, that pisses me off! No wonder the states won't agree on the Uniform National CoP that has been doing the rounds since 1995!!!!....😠

None taken, fact is though that seems to be the way it works most of the time. Could be worse though.

But dodgee Commodores weren't really what I was getting at. Fact is that YES you can put a rotary in your Bug, but there's rules to follow and tests that have to be conducted.

Unless you happen to find a dodgee engineer. Send me a PM and I'll give you his number (just to piss off VWCOOL).

PS Just kidding . . . He's already pissed off... 😉

Clearly some of those hubcaps will pop off under the strain, and for what...5 seconds of uncontrolled warp speed ending in oblivion!! They should be removed first!! :duh:duh

G'day guys, It's been a long time. Due to circumstance I'm
having to sell, all the gear I've purchased for my 13BT conversion.

I have a Sherman Adaptor Plate and Flywheel.
Gas Research Carby to replace the throttle body on a 13bt, hence not having to run catylatic converter, fuel injection etc. (Making It regeristable in SA)
Also for sale a 13bt Series 4 (Import Motor)

Please email me if you have any questions or interest.
Thanks Brett. bholbourn@optusnet.com.au

When converting a dub to a late model engine (ie the 12a) do all the emission laws apply to the engine you install or the year of the bug?
