I do simular conversions with CIS, Digifant and Motronic.  Here are my
experiences

1 - I find this a problem with the Digifant systems.  The computer wants to
run the engine at 800rpm which is too low, especially if it is cold or the
timing is slightly off.

2 - The is common with all 50 degree mounting angle conversions, there are
some manifolds out there that are better than others for clearance.

3 - I have never had this problem.  It is true that the 2.0L engines have
far more compression than the boxers (190PSI isn't uncommon) but the
factory starter never seems to have a problem with any of the conversions
that I have done.

4 - This buzzyness is a function of the exhaust system.  I find the more
things that are attached to the pipe (cat, muffler etc) the worse it gets.
Make sure there are a very GOOD bnracket between the engine and the exhaust
system that allows for ZERO movement.
