During my transmission rebuild, I decided to go ahead and install a Fidanza Lightweight Flywheel and Ralco RZ Lightweight Underdrive Pulley. These were purchased from Cattman years ago.

Here are some weights recorded from the installation:
30.6 pounds - Stock 2k2 Manual Flywheel
15.6 pounds - Fidanza Lightweight Flywheel
5.8 pounds - Stock 2k2 Main Pulley
1.2 pounds - Ralco RZ Lightweight Underdrive Pulley
So, with these two mods, I am saving 19.6 pounds off the crankshaft.





Below are some pictures from the installation.
