Options for replacing 1200 Engine
Just taken delivery of 2 beetles, the '69 is running but the '60 (which I suspect is not a '60 anyway) is not - it has a siezed engine but is
otherwise complete. It will become a project over the next 2 years or so.
What I am looking for is advice - I will eventually need to get an operational motor in there - should I recondition the one thats in there? Or
should I look at trading the dead one against a reconditioned one somewhere? Should I be looking for working ones at wreckers?
Also, I wouldn't mind putting in something bigger, what size could I squeeze in with minimal modification? If $$ permits I'd also like to move up
to 12 volt, what problems can I experience there? Please bear in mind with all these questions that I'm in a country town and we don't exactly have
a large range of mechanics or parts distributors on hand.

the 40hp 1200 had a few problems with it. The rocker box studs tended to pull out and they often needed a repair kit. the 36hp engine was actually
really good, pretty weak but they were very nice, just look at a pair of 36hp heads, they have nice ports and valves. Its difficult to get cylinders
for 1200/1300/1500 these days
There are effectively 4 types of engine cases:
36hp
40hp
1300/1500/1600
1600 dual relief
the 1300/1500/1600 and 1600dual relief are all more or less fully interchangeable
Its pretty easy to put a 1600 in there, the cylinders are readily available. To fit a 1600 engine into an early 6v car:
- If you are staying 6v you need a 1300 flywheel. You cannot fit a 1200 flywheel to a 1300 or larger crank/case.
The early flywheels only work with the early starter motors because of the number of teeth on the rings. If you want to switch to 12v, you need to
get a conversion bushing to fit the 12v starter onto the 6v tranny.
- if you use a 12v flywheel You need to use a early kombi style pressure plate because they are 200mm pressureplates with the early style release
bearing.
- If you use a 12v flywheel you will also need to clearance your transmission bellhousing, its kinda labour intensive as you'll have to slowly grind,
and then bolt on engine, and repeat. You can of course attatch them and turn on the engine and let the flywheel grind it out.
there's a few days work in just doing that. I think its a good idea to go to a 1600 because its just easy to get parts and cheapest. Although
converting all your electrics to 12v is more complicated.
