I am having the tranny rebuilt, I might as well put a lighter flywheel on there right!?! So, I have two options, take the exsisting flywheel and have it machined (anyone know a decent cost to expect?) or, purchase a flywheel that has already been lightened. I don't want to spend 300+ on a damn flywheel.

Oh, is a lightened flywheel a good idea with a turbo!?!
