hehe man the list goes on and on . . . . ignition+cap+coil, bigger injectors (the ones included in kits usually are too small for high boost), boost controller, turbo timers not necessary but nice, good suspension, traction bars are good, gauges, motor mounts inserts (or some nice solid mounts), upgrading radiator & fan is always a good idea too, etc . . . all i can think of off the top of my head right now
i guess a lot also depends on what kit (if any) is used. the only kit imo worth buying is the full-race. all the other kits u will end up changing out parts (to get to 11 secs) like the turbo, manifold, wastegate, bov, etc..
and ya slicks would def be a must to hit an 11sec run.
