Any Difference between JDM and USDM injectors (OBD-1 for VTEC)
Not sure if I searched under the right criteria, but could not find anything related to JDM vs. USDM injectors. I have an H23 and will be swapping in an H22A4, so I know that I will need the 345 cc peak/hold injectors for OBD-1. Any difference between the JDM and USDM VTEC injectors?

Re: (NoVALude)
Is the FPR OE (JDM)? Wow that's a lot of acronyms
THe injectors look and feel identical, I've held both in my hands. I highly doubt they're any different internally heh
4th gen injectors are peak/hold and require a resistor box
5th gen injectors are saturated
So the market doesn't dictate base H22A injectors types, but rather the OBD'ness/generation.

H22s have some of the best injectors for flow. Alot of all motor B series guys buy our used ones for there motors.
They are the same flow for JDM and USDM. 300cc isn't bad for factory.

Re: (ludesrv)
I have a pic, but not sure how to set up here so you can see it....the pic I have was included in a Word document with instructions.
It is oil filled and looks real nice....

345cc for the OBD-I injectors but those would need a resistor box on 92+ Civics/Integras. The 97-01 H22A injectors were only rated at 270cc IIRC which isn't a huge jump over the OE 240cc on B-series DOHC VTEC engines.

Re: (Quick99Si)
Yeah I am swapping out my 92 H23 and throwing in a sleeved H22A4 block with type-s pistons (for now) and Crower cams..... already have the resistor box. I actually bought some injectors a while back, but they are only the replacement set for the H23 (non-VTEC).
