Fuel Injector Question
I'm doing an H2B swap into a civic ek chassis. The tranny (which I just finished putting together last night) is a b16 em1 tranny with a quaife lsd and LS fifth gear swap. The harness is an obd2 vtec harness. The ECU is a chipped P28. The engine is an H22A, but that's about all I know for sure. It has had the head replaced but is all stock except for the valve springs. The injectors are obd2 I believe, but according to the guy I bought it from they came off a B-series motor. How can I identify what the injectors are, and what injectors should I be running with this setup. As of right now the engine is stock, but I have an obx IM port-matched to an oversized throttle body that I plan to run later, along with a possible cam upgrade and maybe even a port/pollish on the head in the future. I'm trying to avoid buying a second set of injectors when I start to upgrade the engine. Any opinions/thoughts would be appreciated as I am VERY new to this and need all the help I can get.

Re: Fuel Injector Question
well i know that b series injectors are 235 cc just like civic and accord but you might wanna get the prelude 290cc OBD2 h22a4 injectors. OBD1 h22a1 is 345cc so go with the 290cc. You really cant tell unless the computer makes the car run like crap. If the computer has a chip for the b series 235cc which i highly doubt you would run hella lean it would blow. If you have 290cc injectors then it should have power all the way up till redline and it wont feel sluggish at take off nor between 5k rpms

Re: Fuel Injector Question
Ya I think I'm going to go with the rc 440 injectors. I can go ahead and tune them down for my application and if I decide to go bigger later on I can add a little more fuel. It's a p28 ecu, not p13 or p30, not sure why I got so mixed up with my numbers. Thanks for commenting, I havn't had much luck with my other posts.

Re: Fuel Injector Question
The p28 has been chipped, supposedly to run the H2B, but I don't know who chipped it or what they chipped it for, so I'm considering just retuning it myself. I really want to get into tuning things myself especially since there's no performance type shops for at least 2 hours. It's already socketed, but I would really like to be able to tune it while it's running, and make small adjustments to it without having to take the ecu cover off and reburn a chip every time I want to tweak it. So far all I've found that will allow for that is Hondata
