Lightened flywheel

[brixspeed]

Can anybody tell me the effects of a lighter flywheel to a diesel engine(pros and cons)? Is it applicable to diesel engines the way it affects gas engines? I am not after any performance gain but that would be a plus. The transmission cannot accept the bigger flywheel of the diesel engine. I was hoping, I could put the flywheel that came with the transmission. The balance of the flywheel to the engine is not an issue but more on the weight.

from what I hear, a lighter flywheel doesn't dampen the vibrations as well
