depends on what tranny you want.

you will need:
-transmission w/ fork & throwout bearing $200-$1500 (cable LS to new ITR)
-pedal assembly ($100 ish from a junkyard)
-clutch master cylinder, fluid resevoir, lines, slave cylinder ($75 for all used, up to $250ish all new)
-linkage ($20-100)
-ECU (OBD1 P75 $40)
-flywheel ($25 used to $300ish new)
-clutch ($25 used to $300ish new)
-3 qt. OEM MTF or synchro max/mesh/wtf ($30)

these are all the extremes, for the most part. i think thats all the parts you will need.... obviously, you will want to change the tranny fuild seals unless you know the trans is in great shape, and i would suggest new OEM clutch fluid components, unless you know they are in good shape.

do the math, and it can be as cheap as $300-400, or as much as a couple grand depending on what you want.

ive actually seen people selling all the parts for a swap, less the tranny itself on here, so keep an eye out.

you might also want to call eddy at Ace autoparts in tampa, ive heard he gets TR guys good quality parts for decent prices.

good luck.
