If it's balanced right it will DROP like a mofo when you let off the gas. if it's not balanced right, your idle will be out of control...

My only experience on the work is on a 4 cylinder 4a-gze, and it idled crazy... shaking, and just out of control. It must have been slightly warped, or damaged...

hmmm..... i dont want my rpms to drop quick. is this cuase its the stock flywheel or does the fidanza do this too? also will the power gain make up for the drop in rpm's?

it has less rotating mass, thus rpms will drop quicker....
if you take an empty shopping cart and push it at say 10mph and let it go...it will stop relatively quickly

if you take a full shopping cart with 10 bags of 40lb dogfood and push it at 10mph and let it go...it will take a while to stop

more mass
more momentum
more time to stop

less mass
less momentum
less time to stop

ultimately, when you let off the gas and pop the clutch, the engine will go down to idle as fast as physics allows it to do.

fidanza, os giken, ogura, stock lightened will all do the same thing...slow down quicker
