Long story short, installed a JDM J35 into my USDM 2003 Honda Pilot and was getting a couple of misfire codes. One code went away when we swapped out a coil pack from the JDM engine, but the other code could possibly be attributed to a broken injector. The mechanic pulled the JDM injector and my USDM one and they are noticeably different. The JDM one is much larger, so he did some searching and said that the injector looks like the same size as a 2004 Pilot injector. Worst case, would it be possible to swap out the JDM fuel rail/injectors for my USDM rail/injectors?

Thank you!
