This may be true as I wasn't into taking my then new Fox apart or having 
a Bentley for a brand new car, let's investigate.....

 From David's VW page:
<http://www.volkswagen.org/EngineSwap/default.htm>

1.8L 87-90 Fox  	81@  	   	JN  	CIS
1.8L 90-93 Fox  	83@  	   	ABG  	Digifant

OK, looks like the motors are 9:1, not quite the 10:1 I have come to 
know as VW High Compression, but not the original Rabbit motor either.

Engine Code -----> 	UM	JM	ABG
Compression Ratio:	9.0:1	9.0:1	9.0:1


Thx for the catch,
