you spin the diff around, so the crown wheel is on the other side of the Gbox

I would say switch the diff around like what craig said; there isn't a single vee out there that I know of that has it upside down...

Yeah - swap the diff around is the normal caper. Curious tho... with the beetle... what's the plan for rear suspension... multi-link of some sort ???
Don't imagine there'd be much room for torsion bars and stuff with a mid engine setup...
I know of a few open wheelers that run a beetle box mounted upside down... believe it had something to do with wanting the starter motor sitting down
lower to help the CoG. Need to make sure the breather hole is well and truly sealed up if going that way I'd think !!!

The upside down thing.
The Hewland Mk8 & Mk9 were originally
VW cased gearboxes and they are up side down.
The upside down thing is you can mount the centre line of the engine lower as upside down the input shaft is below the drive shafts.
Which is pretty important for inline and V config engines.

Turning the box upside-down would create ground clearance problems. OK for engines without a camshaft & oil pump under the crank. Most of the
upside-down boxes, incl. Hewland, run a 'conventional' engine - usually dry sumped.
You will most likely lose some straight-line traction by going mid-engine, but - depending on the suspension setup - gain heaps in the corners.
Cheers, Greg
I'd rather wear a Beetle out by racing it than by polishing it!

I think just turning the G/Box around and swapping the diff over might be the go. Was going to go with a set up similar to independant rear with half
chasis under the beetle to give enough clearance and keep wheels tracking straight up and down
