i personally have not done one. it IS doable. you shouldnt need a new engine (unless the old one is rubbish) but you (obviously) will need the tranny. you'll also need a clutch master and slave cylinder (available at any auto parts store), clutch assembly, flywheel (autotragics have flexplates, not the same thing), shifter assembly, shift knob and boot optional, clutch pedal, and a ecu for a manual tranny (not necessarily required from what i hear but i does eliminate the CEL coming on for messed up tranny codes and various what-not-ery)
