Back in 2001, I converted my automatic to a 5-speed manual. I think I was the second person to do this to a 3S, Hans from GZP was the first and this list actually came from him. I was going through my filing cabinet and ran across the parts list, so I figured I'd post it here for anyone interested in doing it.

As hard as it sounds, it's actually a pretty easy and straight forward conversion. The hardest part was replacing the automatic brake pedal with the standard clutch/brake pedal unit. You have to drill holes through the firewall for the pedal assembly to attach to the clutch master cylinder on the engine side of the firewall. The only thing really tricky was the TCU plug that used to go to the automatic transmission. You have to add a jumper wire on this plug in order for the car to start, and I can't remember which plugs are jumpered. Also, the axles you need are determined by what year your new manual transmission is. If you have a 1990-1992.5 transmission, you need axles from the same years. If you have a 1992.5 and newer transmission, you need axles from a 1992.5 and newer 5-speed car.

lol, yes it was! and I still have the 11 year old print out of it! hah. I never did have to go buy all these parts, thank God. I was able to score a complete transmission with everything I needed from some guy in Oregon IIRC. I paid like $350 for everything.
