Automatic to Manual

I found a 240sx with a bad motor that I am looking to do a swap with. I am wondering how much extra work would it be to put a manual transmission into an automatic car.

pedals... brake and clutch, clutch master and slave cylinder, clutch line, drive shaft, and some wiring for the starter. other than that installation is easy, just drill a few holes in the firewall and bolt everything in... bend up your own clutch line.. unless you have the one from the doner car

you also have computer changes to make so the computer will accept manual trans
