If you're planning on converting your car from auto to manual, the best(and easiest) way is to just go buy one with the manual tranny. You'll be MUCH better off. You'll need a LOT of parts to do the swap. You'll need the trans, obviously, but you're also going to need the shifter, and shift linkages, a new pedal assembly, the clutch hydraulics, a clutch, etc. By the time you're done with parts and labor, you're dropping a LOT of cash. Just go buy one with the 5 speed.
