From what i have read the 84 an 86 turbo cars had low impedance injectors what else should i change or is it just pluggin them in

Top feed & side feed use different fuel rails. You will need to use top feed fuel rails with top feed injectors.

i have a set of top feed rails an injectors from a 84 turbo do i just swap them in no other thing needed

the injectors were recalled in the 84-89 z's. (im pretty sure it was all of them) look it up, get them for free.
