My buddy works at Toyota Direct in Columbus, Oh and he said they would charge for about 10 hours of Labor.
You have a hydraulic clutch in your mr2, no cable.
Take the trans out, the clutch is inside the trans ^_^
how to fix speedometer for Toyota mr2
Check the Clutch Tension in the book there should be some specs as to how tight it should be. It sounds like you have gotten it too tight.
The clutch is hydrolic and should adjust automaticly unless there is a leak or air in the line. there is really no way of adjusting it manually
its located above the passenger fuse box next to the clutch the top relay above the 3 other relays.
You may have a hydrolic clutch. One that takes fluid to make it work, check your clutch fluid.

Does it go into gear with the engine off? If so, I'd be suspicious of the clutch adjustment.
after about 80k
Very top right relay above the fusebox to the left of the clutch. Above the three horizontal relays.
