JDM H22A injectors?
I'm lost between peak & hold and saturated. The more I look for the answer the more I'm confusing myself and now I'm hoping someone here can please help me.
From what I've been gathering, a P13 ECU is OBD1. So if I'm using OBD1 the car needs to use peak and hold injectors with resistor packs?

i'll try and answer your question:
1992-'96 Prelude Non-VTEC are Peak and Hold 240cc
1992-'96 Prelude VTEC are Peak and Hold 345cc
1997-up Prelude VTEC H22/3 are Saturated 280cc
peak and hold honda injectors require a resistor box. saturated do not. obd0 and obd1 injector clips are the same. and obd2 clips are different and require a jumper or splicing in of obd0/1 clips. and from what i am reading, if you have saturated injectors they are obd2. so it will will require obd2 clips (thats if you are obd0/1)
i may be wrong, since i just got rc injectors and clips for my project.
also some info about the car you are working on would help out a ton.

I'm putting a JDM H22A into a 1998 Civic HX. P13 ecu, Brian Crower stage II (N/A) cams, Crower springs and retainers, Competition Clutch Ironman, AEM swap CAI, Greddy header, VAFC2, BDL fuel rail, and some other stuff.....
Sending out the engine harness to Rywire or Hasport to convert.
Looking at upgrading the injectors to RC engineering's 440cc/min, as I'm shooting for between 200/225 whp. Using this: http://www.rceng.com/technical.htm#WORKSHEET , I come up with 390cc/min for 200whp/236bhp and 438cc/min for 225whp/265bhp. Using 18% as a gouge for parasitic loss between the crank and the wheels.
If I'm understanding your post correctly, I can run the saturated injectors as long as I don't run the resistor packs?
This is my first venture into the import world. In the past I've always been a V-8, carburetor(s) guy. Like always though, I'm jumping in head first and trying to figure things out as I go. The more I read the more I question my own sanity.

Thanks.
I was over complicating things, by figuring the injector signal is coming from the ECU and would be different from one OBD to the other. Last thing I want to do at this point is throw some good money away or burn down the engine by being too lean.
So much to learn, so little time.
