I'm not sure if they are going to work on your car. It all depends on if you have a resistor box making your low impedance injectors high.

since the injectors in your car are 13-15ohms seems like you would have to add a resistor box to make low impedance injectors work. And I'm not sure if that can be done. you are able to find high impedance rx7 550cc injectors easily.

that may be the easier route to go.
