Hondata

i about to purchase s300 and wondering if my injectors will work precision 780cc with a resistor box??? in a 99 honda civic gsr swap obd1

as long as the PTE's are peak and hold, why not?

If at all possible use high impedance injectors - they work better than peak and hold injectors.

If the original setup is peak & hold with a resistor box, do you need to take out the resistor box when switching to high impedance injectors?

Yes you do. YOu can depin the clip the resistor box plugs into and swap it to an OBD1/OBD2 style distribution block that uses the end cap that ties all the wires together.

if you are usint the factory green plug on the resistor box, an obd0 dual point dizzy connector works also.
