you probably are looking at like a stage 2 or 3 clutch. I think you have a lot of work to go befor eyou need anything mentioned above. when you do the head gasket are you going to do the head studs? look at companies that make a lightweight flywheel with a heavier clutch. Also you should look into SS clutch lines and removing the restrictor from the slave cylinder. As far as EMS, dont bother when we have ECUflash around..... Plenty of stout evo's running stock ECU's making great power!
