1200 original 61 to hot motor
Hey there,
If you were to do this conversion how would you do it....
1200cc original beetle engine to 1916.. remember this beetle is running 6volt... would you stick a different gearbox in it and convert everything over
to 12v or better yet how can you stick with the 6v?

Hmmm...to run a "hot motor" the preference would be to upgrade to 12V especially for the cold cranking power of the battery to turn over a higher
compression engine. You know how the 6V struggles with a 1200 at times, it would really struggle with the 1.9L+ range. (I'm sure its been done before
though so correct me if I'm wrong anyone reading this).
Also ignition system of choice might play a part?? Not sure.
If you are wanting to maintain the originality of the car for the 6V system, but will be running a big motor....its not that hard to convert back to
6V if necessary if you ever want to sell or go back to original.
If you ask me, I'd go to 12V for sure....stick with the 6V tranny if necessary. May have to clearance the bellhousing though and replace the starter
bush (if using a 12V starter). Otherwise put in a late 60s swing axle beetle (eg. 3.88r&p and 0.89 4th gear as standard) will give a good
compromise without worrying about clearancing for the 200mm clutch.
Hmmm...decisions decisions :o

You need to throw the 1200 engine away as you carnt make it a 1916 using this crankcase or any of the engine components.
You need to start with a dual relief case 1600 engine.

I'm kinda doing the same engine upgrade (but to to a 1916..i wish!) If you can, do what dasdubber sed and get a later gb with taller ratios. Change
to 12v (brighter headlights, easier starts in the morning etc..) and it would be wise to upgrade your brakes too(if you still have drums all 'round)
stopping in time is good!
What sized tyres are ya gonna be running?
good luck!

I was thinking similar, I have a dead 1200 engine and are currently looking around for a replacement engine. Once I have the dead 1200 out, what can
I do with it? I am often told that you can no longer source 1200 parts......can I get it bored out safely to a larger-size engine? What are the rare
parts and can I get around that if I enlarge it?
Or.....will that particular engine always have parts shortages?

If the parts are hard to find now, they ain't gonna get any easier in 5 years! yeh, ur best bet is to get a 1500 or 1600, but then you'll probably
have to change the tinware, electrics?, flywheel, starter even the gearbox might be a good idea so you can take advantage of the extra power by having
taller ratios for cruising... also, you may want to upgrade ya brakes..
yup.. domino effect at its best....

Unless you are going to reuse the 1200 in relatively stock form it is not of much use to you. (I know I have a dead 1200 I have to get rid of too). I
had my old 1200 bored out so it was 1384cc (the "big bore kit" at the time). Stock stroke though. The single port heads will be a big
limitation.....it is far easier to source a 1600 twin port engine and go from there.....or if you want to spend even more due to other "domino
effects" try a type IV conversion - hopefully it will be worth it in the long run (I know, I am in the process of this right now).

tim, 12 volts the way to go,and as others have said change the gearbox for a better ratio one or you will be reving the tits off it to get anywhereat
top end of the scale, i too have a 1200 in pieces under a tarp as was cactus so went to 1300 but still 6 volt:cussing as she is a bit lazy at starting
probably my next step in improving my Misty
aand dont forget the brakes need upgrading

Go 12Volts, at least this way you will be able to see at night. I wish I could have afforded a big motor since I just cooked the 1300. Ended up with a
1500 and now need to upgrade the brakes.
Why stop at 1916, why not go to 2100 or bigger?
