mana sifoo :P
if i were u, the option i would take is the first one, plus a little more: exedy 3 puck clutch for 4g15, and a slightly lightened and balanced flywheel...
OR get a slightly larger flywheel so u can use a larger 1.6 racing clutch...if u wanna use standard 1.6/1.8 clutch, like u sed, during enthusiastic driving it will lose grip, dun 4get it is still an oem clutch designed more for comfort than anything else, of kos still better than standard 1.3 clutch la
ur engine modded lots edi...no more standard
the 1.5 3 puck clutch is nice, pedal pressure is acceptable, and it bites...after 1-2 months of using it, with lots of enthusiastic driving, no slips at all, just that the initial 'juddering' upon take off, is less, not sure whether this is a sign of the clutch settling in or what :P
i like the idea of using back ori flywheel la, lighten a bit, engine more rev-happy...
