this may be a stupid question, but i am going to be boosting my 91 hatch. i have a DOHC ZC in it. i want to get larger injectors but i was wondering how because of it being OBD0. factory it is setup for low impedence injectors. do i need to convert my car to OBD1 with a jumper harness,dizzy,etc.? so i can run high impedence injecers because that is all i see available or is there another way? thanks.

 

Low impedance injectors are also known as peak and hold injectors. You can also run dsm 450cc injectors which are low impedance. Check out http://www.rceng.com for injectors.

 

thanks for the info. are all dsm 450's peak-hold? or just certain years or just OBD 1 for example?

 

you can run both without switching to obd1

low impediance peak and hold inj. is what your car has and it setup with now.

you can also use saturated injectors if you want to. BUT you must remove the black box(inj resistor box) looks like a heatsink in top right of engine bay if your in front of car. solder and connect them to the 1 wire.

camp1320.com has prices on peak hold and saturated type. and already machined to fit our hondas.

450cc dsm need some machining to fit prelude 310s fit right but you must get rid of resistor box since they are saturated.
