Lightened Flywheel, 12lb or 9lb

[AzCivic]

I think the way a Civic would lose "torque" with a lightened flywheel is that it would lose the momentum of the heavier flywheel when going into gear, which should be able to be overcome by revving the engine higher. Granted i didn't read that article but thats just what i'm thinking. So does anyone know the stock weight of my flywheel??
