I am going to pull the injectors on my SR tomorrow and see if they are the reason the engine isn't running smoothly. For some reason I feel like they are the problem. The question is I need new o rings for them, can I just get 0 rings for a 300zx TT? I hear they are a direct swap for the injectors the sr comes with so does that mean I can use the o-ring kit for them as well?

Should Work. I belive the 300 uses the same 370s... if not the Sentra ones should work
