I was bored and I found my stock flywheel in the garage so i plopped it down on our scale. Weighs 21lbs even. Something to keep in mind when looking for a lightweight flywheel

Here some for the RB25 I did a few years ago. Was weighed on a bathroom scale so don't expect accuracy

Block: water pump, ac/ps brackets; 150lbsCrank: with crank girdle; 65 lbshead: intake/exhaust manifold, no valve covers and coils; 110lbsPistons: with rod bolts and rods; 15lbsoil pan: 7 lbsvalve covers: both with coil pack cover; 10lbsRear oil seal cover,oil pump, crank pulley; 10lbsFlywheel: with ACT rb25 PP and disk; 35lbsstock turbo; 15lbs

So that puts the engine at

417 lbs with all major parts.
