Could anyone tell me if a 1200 box would stand up to 1600 motor? any disadvantages or advantages? problems i could face?
Cheers

Question: 1600tp with 1200 gearbox

The diff ratio of the 1200 was 4.375 to 1...
The gearbox diff ratio of the Superbeetles was usually
3.875 to 1...
going by My manuals, so You would be revving the engine more when on the highway... with the lower diff ratio..
but it would give You more pickup in traffic...

How they would stand up to the extra horsepower I don't know....
Add some Molybond to the gearbox oil will help....
I think if You do a lot of highway work, the fuel economy would be gone, with the engine revving much more than with a super gearbox....
If You do mainly city traffic, it may be OK... You would be able to drive sometimes in top gear....
the 1200 had a 180mm clutch plate where the 1600 had a 200mm clutch.... so there are some differences....
like using a 6 volt starter motor... with a conversion bush..
If You were putting a 1200 gearbox in a super beetle.... that is much more complicated...
1200 gearboxes have Swing axles - supers have CV Joints and IRS rear end....
unless You are using a 1200 gearbox in a 1500 beetle with a 1600 engine.... swing axles... in both,,,

this is what I am running at the moment...ditto to everything Lee said
I do find it a little short in gears but as I mainly do city driving I like it.. You will have to grind the bellhousing to fit the 1600 but this is minor really
A 1600's Horsepower should not affect the 1200 box..

yea it;ll work with a bit of grinding and the right flywheel and clutch
theres plenty getting around like it already
it'll just be geared like a mack truck
ie pedestrians are still walking faster than u by the time ur in 4th

My brother's first car was a Baja. It ended up with a twin-kadron, big-cammed Stan Pobjoy-built 1640 in it. Off-road, jumps, drag racing idiots in Commodores, all with BFG muds on the rear and never broke a 1200 diff. I reckon it went close, but it never broke...

The best you'll do in a swinger chassis is a 1500 box with 4.1 R&P. That will give you four-stud wheels too

The rpms that you do with the 1600 100km/h will be the same as they were with the 1200.
The later trannys may be in better shape however.
