sometimes thep people on here amaze me....
anyways... Injectors are going to be the same in CC.. (not sure on Impedence)
I am not sure what 2000 I4 Camry ( MIC0417 )

has seen but all the 2000's I know of are 5sfe....
I have a 1997 that i swapped a 94 5sfe into and it was a PAIN in the @ss!!
A gen 3 engine is not a DIS motor therefore signifently different and the CAS sensor is all different..
I basically had to almost fully dissamble both motors and make a good one out of all the parts I had.. again Pain in the @SS!!!
going form a gen 4 to a gen 3 may be easier did not do that one..
