how much hp can 99 civic d16y8 injectors take? what r the best injectors? high impedence or low inpedence?

 

not much, best is not the answer, with out knowing what ems you are running, if the ecu is stock based.

up to 750 saturated can be ran on a stock ecu ( chipped ofcourse) with out a resistor box (obd1 ofcourse)

above 750 peak and hold will necessitate a resistor box for an obd1 ecu.

 

DSM injectors (450cc's) are a pretty good deal if you decide to deal with forced induction or have a crazy NA build.

 

well i only desire around 200whp for now, later when i get another car, i'll add internals to it. i was thinkin 440cc. what should i do to the ecu?
