I think you may need the fuel pump and lines?
You'll need the whole intake system obviously, which should come with the engine, and the ECU.
Not too sure what exhaust parts you need, but you should get away with using spacers on your current system from the downpipe back if it is standard. Not sure about the downpipe fitment.
You may want to think about things like new clocks (8k rpm limit), better brakes, 16v anti-roll bar and suspension, etc.
