Default H22a4 to H22a1 injectors? Will it work?

I have a 99 prelude engine, but my injector clips are for OBD1 Hondas (96 and earlier). Could I use the injectors meant for the H22a1 ( VTEC of Course)? Or would I damage anything? Lost of power? What injectors should I use? should I convert the clips for Obd2?This engine is in a 96 Civic hatback with a p13 ECU(92-96 prelude Vtec).I do not have a resistor box wired in car. Would I need one to use H22a1 injectors?

You'd need to use a different ECU and wire in a resistor box for it to work. The '97+ injectors are Saturated injectors, and the '92-'96 H22A injectors are Peak & Hold. Basically that means that they run off of different voltage measurements. Some people have use the peak and hold injectors, in a set up that is for saturated injectors, but there are even more people who have tried and burned out their ECU's doing so.So honestly I would recommend either rewiring the clips back to OBD2, or staying with the OBD1 clips and buying some aftermarket saturated injectors; as long as you don't have a resistor box wired up. Keep in mind that most aftermarket injectors only work with OBD1 clips, so that might be another reason to stick with OBD1. Stock H22A4 injectors are 280cc by the way.
