This has been covered hundreds of times, the problem is trying to get a good set of search terms.
Long story short is that you would only want to swap in the short block. Keep all the stock S5 intakes and electronics. If you try and swap over the S4 electronics, then things get complicated really quickly.
As far as power, remember that the S4 engine has 20HP less then the S5.
