Rotorchase

ok first off did a search, helped some. little background, have s5, with a blown motor, got s4 motor. now i do have the wiring harness to s4 also but if i were to use the s5 intake manifold, how much of a pita would be swapping sensors? any tips would be appretiated.
Another question since its an s4 and the engine is out i know the pulsation dampener is a pain, but i have the s5 fuel lines, all ive been able to find searching is about banjo bolts. Is there anything i should know on using the s5 fuel lines in place of the s4 rail? thank you in advance.
