A lightened flywheel is not desired when you want torque.  You boxer is not
disigned for high revvs.  When I had my boxer it would always cut out at
aprox 5500 RPM which I find can be dangerous in emmergency situations.

Want a high revving engine?  Install a 2.0L 8V 4 banger.  I take mine to
6500 RPM every now and again to make sure there is no carbon on the valves!
 They love high RPMs.  The only problem is that after about 5500 RPM the
power begins to fall off with the stock cam.  A longer duration higher lift
cam will fix that problem, but you will loose bottom end power if you get
too carried away.  The Audi 5 cylinders will rev higher than your boxer but
they really start to make just noise after 5000 rpm instead of power.  BIG
bucks for Audi cams!
