the M116 engine in 3.5 format came with either 0280 150 024 or 280 155 203 injectors which according to my book run at 310cc/hr at 28.5 psi.

all of these injectors are low ohm at about 3.2 ohm

the nissan injectors will bolt straight in on your fuel rail and the 300zx are rated at 280cc to 310cc/hr at 28.5 to 32psi and are 2.7 ohm resistance so they should work just fine. but I have not done it myself so I dont know - I can tell you they would be better than using the 036 injectors that you see on ********.

I use the brown top nissan 300zx injectors on their own rail and then a piping bender to bend the rail to get the holes to line up. I also use a megasquirt controller to control them

lastly remember if you do use the nissan ones then replace all of your lines and push the pressure to 32 to 35 psi. I use the proper braided silicone pipe at 7.5mm and only full clamps. If I can help let me know I should be around the forum more this year and yes if you decide to clean yours I can send you pointers and parts. below are the nissan injectors, and piping I use
cheers
