Supercharged or naturally aspirated?
EGR and tubes - Yup. Two different setups.
CPS and Crank Pulley - If you mean the crank/cam sensors and the HB, no they do not need to be swapped. If it were a 92 engine, then yes.
MAF - Yes on that one too. If you have the complete engine to swap in (intake manifold and throttle body attached), all you need to swap in is the MAF sensor.
Knock sensor locations - L27 to L27 are the same locations (up front, above where the oil filler tube goes into the block).
02 - When doing a swap, I usually try to go for new instead of swapping. But yes, the O2 sensors are different in that the '94 uses a 4-wire setup.
Keep in mind there were *slight* internal differences, mainly in the piston rings and bearing design. Nothing that will keep you from using the motor if you already have it.
Any work going to be done to the "new" motor before getting swapped?
