You need the B204FT engine, including all accesories, manifolds, turbo, intercooler, the engine computer, the engine wiring harness, and the fuel pump(s). You should try to have the donor car nearby to get other small parts that you may need, like the fan shroud, coolant overflow bottle, and other relays & electronics. I don't know exactly what you will need because I've never done an engine swap like this, and the United States never used either the B230E or the B204FT, so I'm not very familiar with them. I do know that the B204FT made 200HP. You should be able to get 250-300HP with a 3" exhaust and more boost, but your transmission probably won't take that much power.
