You will not cause damage to either the coil or ignition by using a 12v coil 
(which is what yours now probably is) on a ballasted system, but you *will* 
have a weak spark.  This could cause difficult starting under adverse 
conditions, although being a Sport coil with a slightly more powerful spark 
this is mitigated somewhat.

12v standard coils measure about 3 ohms across the primary, 6v coils measure 
about 1.5 ohms.  A Sport coil I have measures about 2.4 ohms.

Ideally you should have a 6v coil on your system, which together with the 
ballast and the ballast bypass system when cranking actually results in a 
more powerful spark when cranking than when running.  You *could* bypass the 
ballast and hence get the full running spark with your 12v coil, but you 
would lose the 'boost' effect when starting.  I recommend you fit a 6v coil.
