Welcome to Zdriver man. Since you own a Z31 ('84-'89 300zx). You need to go to that section. To get the help you need. This is the Z32 forum ('90-'96 300zx). Hope that helped you out. Good luck.

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.

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.
