Default prelude injector sizes?

what are the prelude injector sizes and for what years? and what years will work in my first gen b16. I have access to a blown h23 so i wanna know if those injectors will work. thank you.

OBD1 H22 injectors are rated by RC at 345cc. I had mine flowtested by them a few months ago. RC claims the OBD2 H22 injectors to flow 290cc.
I don't know for a fact, but I believe the H23 injectors are rated at 240cc like the B series. Give RC a call and ask a tech for accurate info.

'97+ Prelude injectors are 290cc/min

Let's get something straight, they aren't OBDI and OBDII injectors, they go by engine design

H22A1 injectors, which includes 93-95 OBDI and 96 OBDII ar the 310-330 (RC says 345?) Peak and Hold Type INjectors, they require an external resistor box. They are high impendance injectors.

H22A4 injectors, which is 97-01 OBDII engines, are the 290cc Saturated type injectors. I have not seen them myself, but the resistor is 'on' the injector. they are low impedance.

Unfortunately I know nothing about OBDO....but OBDI and OBDII ecus send the same injector signal, it's just a matter of using the right resistor/injector combo to make it work.

thank you, that answers my question. 92-95 SR-V injectors it is then.

no that's actually 93-96 SR-V injectors. No SR-Vs in 92 and the 96 has the same ones

What the majority of people are talking about when they are saying OBDI and OBDII injectors is speaking about the injector plugs...the OBDI and OBDII injector plugs are different, and would require you to change out the plugs to get an injector from an OBDI car to work in an OBDII car...hence the reason of using the '97+ Prelude injectors, allowing you to use the injectors as a simple drop-in modification, not wiring changes needed.

I´m using 97+ prelude injectors on my ITR and i believe they´re high impedance, saturated.

lets get something MORE straight, and less WRONG...

Peak and Hold are LOW impedance ie 2-4ohms

Saturated are HIGH impedance ie 10-14 ohms.

OK?
