What is the weight of your 3SGE lightened flywheel?
 

the 3SG ones advertised above are 6.2-6.4kg. i can get them down to just under 6kg with more time-consuming/expensive machining
 
on everyday street driven cars anything under 6kg has a noticable (negative) effect and prevents nice idle they have when stock. if its a real performance monster, then that's not such an issue
