Legally !!
I would think probably 1300cc for a 60s Beetle..
and 1600cc for the 70s beetle...
without engineers certificates etc...
I know everyone puts 1600s in everything
I have heard where two speed wipers are needed with larger engines.. but that may be on an engineers certificate too...

How do they equate cc's to rotary engines ?

A 12a = 1.2lt and a 13b=1.3lt. You then have to multiply this by 1.7 (I think)
So a 12a= 2lt
13b=2.2lt
Then if it is a turbo rotary.......................................... :jesus
I think you then need to multiply it by 1.7 again ?????????

ok, the NSW rules are briefly described here (QLD rules are almost the same);
http://www.rta.nsw.gov.au/registration/downloads/vsi06.pdf
So, without approval you can go 15% bigger than the maximum engine offered by the manufacturer for that model, which for a later 1600 beetle is
1840cc. So a 1915 requires a blue plate (qld) or papers in nsw. I had a blue plate for my old 1915.
To go bigger than the 15% rule, you will need various safety upgrades. These are;
a) Seat belts must be installed for all seating positions. Lap/sash seat belts are required for all front
and rear outboard seating positions. Lap/sash or lap belts shall be fitted to inboard seating
positions (this requirement does not apply to small buses. No upgrading of seat belts is required
for these vehicles);
b) Windscreen washers must be fitted;
c) Two speed windscreen wipers with a fast speed of at least 45 cycles per minute and a slow speed
of at least 20 cycles per minute must be fitted. (Single speed wipers are acceptable if the speed
is 45 cycles per minute or more);
d) A windscreen demister must be fitted;
e) There must be an external mirror on the drivers side (and on the passengers side if there is not an
effective internal rear view mirror);
f) If the replacement engine has a capacity more than 45% above that of the largest optional engine
for the vehicle and the vehicle is “pre ADR 10/--”, a collapsible steering column is to be fitted;
g) Flashing turn indicator lights to be fitted at the front and rear of the vehicle if not originally
provided on the vehicle;
h) Automotive safety glass (either marked accordingly or can be shown to be safety glass) shall be
fitted for the windscreen and other windows in the vehicle.
In addition to that table, the engineer may ask for upgraded brakes or basically anything he feels is required to make the vehicle safe. When I went
to the V6 my engineer wanted to see rear disc brakes, and quite frankly so did I.
You will then be limited to engine capacity as per this table;
Now most later beetles are around the 840kg mark, the exact weight depend on which VW manual or handbook your looking at. The engineer will accept any
weight that looks like it comes from a reliable source.
Now assuming 840kg, you are limited to;
1 - turbo/supercharged - 840kgx2.5 = 2100cc
2 - naturally aspirated - 840kgx3.0 = 2520cc.
Hence I went for a 2500cc V6 over a 2lt turbo suby.
Notice it says multiply the rotary capacity by 2, so a 13B is a 2.6lt, a 12A is a 2.4lt. Therefore there is absolutely no way a 13B turbo is legal in
a beetle (or buggy).
Also note the table says;
| Quote: | “Original
weight” is the original (unmodified) “tare weight” of the sedan version of the vehicle model fitted
with the largest engine available for the model but without optional accessories such as air
conditioning and tow bar.
|
A lot of engineers are using this rule against it's original intent, and assuming that for a buggy you should use the sedan weight, which is the
beetle. So people are putting 2lt turbo motors into 600kg buggies, cos the rules say not to use the modified weight.
Then of course if you build an individually constructed vehicle you can go to any engine size you like.

Hi
I have a 1967 1300 glovebox owners manual. The weight quoted in it for a 1300 bug is 1638 pounds (avoirdupois) is equivalent to: 742.984 kilograms
742.984 x 3 = 2228.952 cc max NA
742.984 x 2.5 = 1857.46 cc forced induction.
My 1972 Superbug glovebox owners manual quotes 870 kgs
870 x 3 = 2610 cc NA
870 x 2.5 = 2175 cc forced induction.
Does anyone else have glovebox owners maunals so we can post the weights?

in NSW the RTA tell you to get your own weigh bridge ticket, so before you do a conversion, you could always get it weighed with a full tank of fuel
and 4 bags of cement
If it aint broke,

well actually the pdf link I posted is from the RTA, and it says
| Quote: | “Original
weight” is the original (unmodified) “tare weight” of the sedan version of the vehicle model fitted with the largest engine available for the
model but without optional accessories such as air conditioning and tow bar.
|
Which is written so that people don't use weighbridge tickets because the vehicle can be sand bagged. For later cars the weight should come off
the compliance plate, or stamped elsewhere on the vehicle.

Nice attitude, just don't bother insuring the car as the insurance company won't pay anything in an accident. Don't hit anything you
can't afford.

It's attitudes like that that make it harder for everyone involved. 
Doing things properly takes very little extra effort so why not do it properly. The rules are there to protect ME from YOU.
The rules are to stop some backyard mechanic deciding to put a 5L V8 in a 1960 Beetle without doing appropriate other mods. If there wasn't these
rules he'd plonk it in, hit the throttle, and torque steer off the road into me walking down the foot path.
The rules are generally very reasonable. Heck, Wes has a fully legal 2.5L V6 in his beetle. Blue plated... done... properly. :thumb
Based on the regulations specified above a 2 litre type IV is a fully legal mod if done correctly so why not do it correctly and get the approval
paper or mod plate? 
Mike
PS. So if I steel your car, it's not illegal to do until I get caught??

VW cases
As I understand it. The maximum capacity is based on the standard capacity of the engine block.
Therefore, you can use any size engine providing the standard capacity of the engine is within the guidelines.
Accordingly, I am free to bore and stroke my engine out.
Sounds silly, but VW engines are the exception to most engineering limitations.
Where your average watercooled engine might only go out an extra 200-300cc maximum, VW engines will go out an extra 900cc.
Now when it comes to insurance, I am guessing that cars with engines of this callibure need specialist insurance anyway. To get this the company needs
all the important specs of the car. Be honest and do it properly. Wes is absolutely right.
Let me give the bonehead who suggested illegal modifications a senario to think about.
Just imagine some idiot in a highly powerful, illegally modified Torana wiped out you prize Vw while your wife/girlfriend was driving it.
Firstly: His insurance company would refuse to cover the damages to your car leaving you without a car even though you weren't in the wrong.
Secondly: The insurance company might void his 3rd party personal insurance and refuse to cover your partners medical expenses, leaving you out of
pocket again.
Thirdly: you can bet that a low life like that has no money you can sue out of him.
Please don't do illegal stuff. It endangers peoples lifes, livelyhood and gives petrolheads a bad name. Right!

I don't read the rules that way. Even if you found an engineer that did read the rules that way it is the insurance accident investigator and
their legal representitive that you need to convince.
My engineer agreed a 1915 should have a blue plate, but said you'd be pretty unlucky if the insurance company found out, but it should be done.
However if it had twin carbs or looked modified they are more likely to look closer.
For people like me with my car details posted on the internet, I have to be sure everything is legal as I can't argue that I didn't know
that it was modified. I can't use the "oh, is it really a 1915? I thought it was a 1600 when I bought it" excuse.

Height above ground of My number plates??
After reading all the posts here and others about illegal hood jax etc... It looks like My Beetle will be stock standard.. apart from air
horns!! I suppose they are illegal too??? the RTA is killing us.... next they will be measuring how far the hubcaps stand out from the wheels....
about the only thing left... or the height of Your number plate from the ground is a classic.... Who knows??? If My front number plate is on the
front bumper, is it OK to have My rear number plate where it should be??? Lee?

insurance companies
I think you will find that what wes is saying is that the problem is not with the RTA but with the insurance companies.
This should be no surprise, but there is an alternative, no insurance.
Personally I think this is not the better option.
But i will repeat what I said before. If your car is of the calibre that you would spend the money that a 1915 costs, the least you can do is insure
it properly. This involves telling the insurance company everything about the specs of the car and having it legal to begin with.
Wes, I certainly agree with you on that point.
However, the specifics of the engine specs vary greatly as to which engineer signs your certificate. Thats the way it works in NSW. Therefore, alot of
people build something that complies as far as they can see, then they shop around until they find an engineer who will certify it. You will be
pleased to know, that is not the way I have operated.
However, As long as it gets a certificate, it is legal as far as the insurance companies are concerned.

yes I agree Pete. What it actually means is you should be ok, but the person that approved it will be in a lot of trouble.
But my point was, if you have an unapproved 1915 engine, then you don't have a certificate. So you can't tell the insurance company that it
was approved, cos it wasn't. You can say "I asked billy joe if it needed to be approved and he said no it doesn't". They will
either say, no you didn't, or they will ask billy joe and he will say no I didn't so he doesn't get in trouble. Either way your excuse
won't work. That was my point, if that makes sense

and slightly off-track but a similar legal-insurance company subject, tyre size.
In qld the rules say, and I quote
| Quote: | The maximum tyre
width must not be more than 1.3 times wider
than the vehicle manufacturer’s widest optional tyre.
|
Now the person that wrote the tyre rule didn't understand the english language in a legal sense. Note it says, "1.3 times wider".
Legally, that means for a 165 tyre, you can make it 1.3x165 = 214.5mm wider than the original tyre, bringing the total width to 165+214.5=379.5mm
wide.
What they meant to write was "1.3 times the width of the original tyre".
But they didn't, so in QLD it is legally impossible to get prosecuted for having illegally wide tyres (unless you fit wider than 380mm). I have
this on good authority.
Then the only other part of the rules to worry about is "The tyre and rim must not foul wheel arches or suspension components under any
conditions. Steering limit stops should not be adjusted to reduce the turning circle in order to allow the fitting of the tyres and rims."
Comply with that and your sweet.

I think you took what I said out of context. I agree with the rules and agree that appropriate mods need to be done before you drive on the road. My
car has been modified when I transfered the rego from nsw to qld was not required by qld tpt. to have mod plates fitted. After much discussion with
the police when they pulled me up found out that needed mod plates and went and had it done. The mods that I have are 4 wheel disc brakes and bigger
motor all of which was the same as when I had it regod so I went and had it done. A bloke I work with has a cortina with a 351 in it the cops and qld
tpt dont even want to know about it. What I was trying to say is You speak to one guy who says yes you do and another says no that why so many people
just do it and worry later on. I have seen this first hand after doing some tow truck work how many people have mods done have a smash take the car
home and take the mods off put it to original and get away with it. eg. Towed a bloke who rolled his hilux surf. Bigger tyres and a lift kit illegal.
Towed him home and he changed everything back to original got a call to pick it up and took it to an assessing centre who sent it to auction, they
didn't even bat an eyelid at the car. Thats what I meant when I said its only illegal if you get caught. Sorry if this offended anyone it was not
meant to be that way.
