Could someone tell me when the 1600 motor came out in the beetle as I have a 03/1970 bug with 1500 case and is now a 1835.

1500cc x 20% = 300, 1500 + 300 = 1800cc
1600cc x 20% = 320, 1600 + 320 = 1920cc

So if my 03/1970 series bug came out with a 1600cc motor I am ok.
If not I need an engineers certificate because I'm 35 cc over for rego to be legal.
Thanks
Darryl

The only "standard" beetle that had a 1600c engine was the 76 model. Superbugs from 71 had the 1600cc until production ended. Here are the details if you want to have a read http://www.clubvw.org.au/austvw001

Not much help to you but at least you now know.

How are they going to know it is an 1835?

The engine number will be for a 1600.
I read it on samba, so it must be correct.

Darryl are you sure the RMS standard is a 20% increase,from memory it used to be around 15% when I was in the trade. The 1970 bug should have been a 1500.
I stand corrected out of curiosity i just had a look at the VSi 6 and 20% it is .

Is it possible to get a new 1300 or 1200 case? I'm thinking no.

So, when our poor tired, fretted to prices, 1200 or 1300 case needs a rebuild... And the only option is a new 1600 case. What do you do ? 1600 is over 20% increase on a 1300.

You need that engineered - when there is no alternative ? Is that right?

Is rms paying that close attention to the engine codes. And don't the new cases come blank? So what code is put on - and by who?



....Please pm me if required.

Yes it is an issue.

Some low life owners go as far as buying a blank 1600 case and stamping it with the 1200's engine number.

The hide of them!

Thanks all who answered with info and advice.
But I want to be legal because if an insurance company wanted to cancel on a claim and pulled down on the motor they would due to the cc being over the RMS 20% rule.
Also needed engineers certificate with the steering wheel/ boss, exhaust 95 dcb just under 96, blinkers, wheels and tyres and retractable seat belts.
I just spoke to my engineer who told me that the 71 bug is ok as it is the same as the 02/71 model suspension wise when the 1600 came out, so I'll be sweet and legal.

Thanks again
Darryl

not the same suspension. the 71 standard was only a 1500 single port and had beam suspension.
the 71 super had struts and a 1600 twin port.

The solution is simple -get an engineers certificate but get him to cover all of the other mods that you have done and weren't going to mention,that way it is only one certificate and no dramas.

You could always get a 10% bigger engine and then rev it 10% higher............

Nah, I'm an old fart so legal she goes.
If per'say you had a major accident, people injured etc. and the powers to be checked modifications on my vehicle and found non compliance I would be in all kinds of poo.
It's better to take the extra effort now to get it all sorted, and if it is over the 20% rule ( I'm 35 cc over) and the engineer is going to certify it as safe.

I thought new engineering rules allowed power to weight ratio HP increase taking into account other mods such as brakes abd suspension.
