want to swap d16 to b16a2

hi,
i was thinking about swapping my stock civic si hatchback into the b16a2 motor, but people say that i need all this and that. i didn't know that. this is my first swap and i need some information. if i buy the b16a2 motor what else would i need to have a good fit onto my car without any hassel. i know i need the motor, the transmission for that motor and the mounts. what else??? is the b16a2 a perfect fit for the 94 civic hatchback si? do i need to buy any mounts? i'm a newbie at this so anyhting that can help me find out what i need it good.
thank you,

you need a ecu and wiring harnes. You will probably need some B16 cv axles also. Good luck.
