Unless the car is in great condition with decent miles or if you can do ALL the work yourself, I'd suggest waiting until you can get a car that comes as a MT. You'll need new trans, shift linkage,shifter,clutch pedal and cable or hydraulic depending on the type of tranny, shift boot, new gauge cluster, and I believe some changes done to the ECU just to name a few. I read somewhere about someone else having this done and it was a ridiculous amount of sh1t they had to do. Unless you can get ALL this for the low low and do ALL the work yourself, I wouldn't recommend it. If you are going to get a 5 speed and put it on a non turbo ride, I'd suggest the b16a2 tranny, short gears and quick as hell if it will match your set up.
