Can anyone explain the difference according to some searching the 96-00 civic injectors are 240cc like our integra's but area a "saturated" 240cc vs peak and hold 240cc of all the b-series one's. I'm asking cause my friend would like my 99 dx(d16y7) injectors for his bolt on gsr with a 255 pump stock fpr. He claims it's running rich so idk he can have them for all I care but I don't want something bad happening and it coming back at me lol, so with a 255 pump and dx injectors on a bolt on gsr is there any risks ?. Or are dx injectors 190cc as I've heard a few times.

thanks

Not all 96-00 civic injectors are 240cc. 96-97 have the same part number as 99-00 si, being the 240's, but 98-00 lx/dx/hx are 190cc.

Cant comment on saturated vs peak and hold, because I have no clue lol

Obd0 b series injectors are peak and hold and require a resistor box. Obd1 and obd2 are saturared and dont require the resistor box.

Oh snap post 1000

Also, from what ive read, if you use obd0 injectors without the resistor box youll blow up the injector drivers in the ecu.

Also saturated and peak and hold refer to how the injector operates.
Peak and hold injectors peak at a certian current to open them, then reduce current to enough to hold them for one pulse width. I guess its so the injectors snap open real fast, but reduce current to only what they require to stay open to keep them from overheating.

Saturated I think just use one current level to open, so they apparently are slower to respond but run cooler since they dont have the current spike peak and hold injectors have

ahhh ok thanks good to know so I guess that doesn't play into my scenario, any danger in running 190cc's on a bolt on gsr with a 255 pump tho ? we threw them in the car feel a little down of power so to say...

Oh god please dont do that. The stock injectors are 240cc and are already pushing it on a bolt on gsr. For what its worth, I looked in smanager to see the duty cycle if I extended my rev limit to 8500rpm on a b18a1 map, and it was at like 90%+ duty cycle.
I think the stock injectors max out around the 200hp mark.

Those 190cc injectors would probably max out on a bone stock gsr.

ok I was defiantly skeptical of using them after we drove it down the road. The affect would be you lean it out to **** right ?

96-00 Civic HX, CX, DX, LX are all the same part number 06164-P2A-000 and flow rate 190CC. 96-00 Civic Si/EX are all 240CC but have two different part numbers 06164-P2J-000 and 06164-P8A-A00.

Yep, lean as **** and no good for the engine.

How would you tell the difference between b-series and d-series injectors?

B_Swapped93

Good question I used y8 injectors on a friends ls swap they honestly seemed the same I do have a set of y7(190cc) injectors lying around and a random gsr one lol. tbh they seriously seem the same so I'm in to know.

There's really no way to tell between the 190 and 240 injectors. some people say there's a different colored paint mark on the 190's but I don't trust that.

The OBD2 EX, Si and GSR use the same injectors, no difference at all. Same ones go on the non-Vtec accord & prelude.

The SManager duty cycle map isn't really that accurate, FYI.

Peak & Hold is OBD0 except for the H22, an OBD2 harness wouldn't fit on them anyway.
