what oem injectors can i run????

Most top feed injectors can be made to fit, just a question of clips, impedance and type (peak and hold versus saturated), and whether spacers are needed for the injectors or if a riser is needed for the fuel rail and whether or not the rail or head need to be bored out... I can't remember the diameter of our injector inlets or outlets right now.

The first thing you need to be sure of is that the injectors are low impedance and peak and hold... low impedance + saturated is uncommon (unless it's a saturated injector and there's something wrong with it), so generally, if the impedance is low it's a peak and hold type and you're good.

I didn't think the RX7 injectors needed different clips, you sure? What's the flow rating, impedance, and what are the dimensions of those DSMs?
