Hi i have been told that i could fit a 1600 motor into my oval is there much involved in doing this? I have an ex army 10 kva genset that has a real good 1600 single port motor maybe i can use that will it fit up to the oval's gearbox is there any problems with the flywheel fitment etc can i use the oval's dog house cooler etc. The 1600 also has the small generater stand so maybe i can fit the 6v gen of the oval onto it as well.
Sorry for so many questions just i have never done much on VW's before.
thanks for any help
cheers

Yep, pretty easy swap. Youll have to fit the flywheel from the 6 volt (oval) motor to the 1600. And use the 6 volt genny and you could even swap the genny stand.

you will need to trim the rear peice of cooling tin to fit.
Right hand side wire bail that holds the valve cover on may also touch the body near the bumper mounts

Grey57's right about the righthand rocker cover retaining wire - mine fouled on the bodywork a bit. The gearbox compatibility will probably be an issue too. You may need to use a split bus gearbox nose cone. I think Empi might sell an adapter to overcome this problem.

Does the 1200 flywheel not fit onto the 1600 motor?
I have a 1972 beetle that has a swing axle gearbox and a 1600 twinport motor can the gearbox complete with axles swap into the oval just a thought?
thanks

im not certain but i think the sw gearbox and engine will fit but only with a different nose cone. the front gearbox mount on a pre 61 is very high and the normal nose cone off a later gearbox wont fit

Just a query following up on this in terms of exhaust choice.

We are fitting a 1600 twin port into my fathers 54 beetle, and i'm not sure what off shelf exhaust systems will fit whilst still clearing the rear valance as a 54 has no exhaust cutouts.

Any tips? (no pun intended)

Anything other than a 1200 means the engine is about 20mm wider so you may find that the head tinware fouls on the engine trays.
I know that even putting my 1200 back in the 59 shell was pretty tight with the engine seal in place.

Maybe measure the engine from the edge of each head tin to make sure she'll slip between the engine trays 🙂

6V flywheel will fit no worries but it may be worthwhile have a groove machined in the top of the bore that the flywheel fits into. On later 12V flywheels this groove is there for the O ring seal that takes the place of the old paper or metal gasket on the nose of the crank. IMO the O ring does a more reliable job of sealing than the paper gaskets and also makes setting the endfloat a bit easier.

Oh, and make sure the clutch pressure plate has the central contact ring for the clutch throw out bearing to push against. Fine if an old style 3 finger pressure plate but newer multi spring finger plates need to have the central ring to work properly with the early type throw out bearing 🙂

Oh, and if keeping it 6V then you'll need to swap the coil, genny and choke if the ones on the 1600 are 12v.
madness is in the eye of the beholder 👍
