Alright, so after weeks of searching this site and others without finding a straight answer, I figured it's time I hop on and ask it outright.

I'm currently in the process of switching out parts on my '96 LS from OBD2 to OBD1, particularly the ECU (so I can install an S300) and the injectors (getting a turbo thrown on it, need all the fuel I can get). The original OBD2 wiring harness is staying in, since I honestly don't feel nearly confident enough to mess with all that. My main concern is with a resistor box for injectors. The new ones going in are peak/hold, just as the OEM ones are. However, there is no resistor box in my engine bay (at least as I can see), even though the current injectors are peak/hold, which already has me confused.

I see a lot of people saying that peak/hold injectors require a resistor box, but if I'm already running those kind without a resistor box, why would I need to install one if I'm keeping the same type of injectors. My head is spinning with all of this already, so I'm just hoping someone can tell me just what needs to be done. Thanks for any help or advice ya'll might have.

 

It's been a while since I tackled this issue with my car(89 civic). I thought that Honda had only used the injectors that require a resistor box in the OBD0 cars, not OBD1 or OBD2. I'm not 100% sure but I believe you will not need the box for aftermarket injectors, at least I didn't when I was running RC injectors.

 

OBD1 and OBD2 Integra injectors ARE NOT PEAK and HOLD type. They are saturated. You need to stop listening to people giving false information.
