as long as you have a "normal" clutch pedal feel, and it returns back up when released, its not a problem with hydraulics.
on the same note, if you have the speedo moving when you put it in gear, and you dont move, then it is either a driveshaft or diff issue...which i dont see being the problem either.
clutch, yes, esp being its on a "fad car" that everyone wants to race

i have seen clutches break the hub from the center of them, blow all the springs out so the clutch wont release, explode and take out the bellhousing (and legs of driver if not careful!) etc....
there is a remote possibility that the mainshaft of the tranny is broken....but you would hear that.
and that is a relatively easy clutch to do...good starter!
