Shit just basically the much small piston pocket it seems to me.  You
could probably get a similar effect in a regular 2.1 by using 1.9 pistons
though you'd have to check pin heights to see if stuff cleared.  Of course
before everyone runs out there searching for the 10-15 hp this even began
to net you, I'd consider the one little key about that engine and that CR.

VW recc of 98 OCTANE!!!!

Yep, where you going to buy that in the US, going to run super blue
racing or avgas in you waterboxer at $4 a gallon for 15 horsepower???

You'd pay for a 5 cylinder even at the ridiculous costs for the conversion
parts here in the US pretty quick.

It has always amazed me to no end that VW made the engine in this
tune as if it isn't a detonation king in the 9.0:1 form, I still can't fathom
why even the MV wasn't equipped with a knock sensor ignition, I mean
it was hitting all the other product line across the board in '85 or so.

Oh could be that they just couldn't ever get the sensor not to hear those
persistent rod and lifter noises 8-)
