Does anyone know if the B16 injectors push more cc of fuel than the D16? I would figure that they would b/c its a bigger and more HP motor but wanted to be sure. I want to put some in my d16y8 to increase the fuel by a little bit. Well thats if they can even be installed in that motor.

 

240cc injectors for b16 and i think it's the same for the d16 but they have different duty cycles... can anyone confirm this?

 

all civic and integra injectors flow 240cc, idk about the prelude injectors, they maybe the same maybe not idk. only difference is duty cycle which is controlled by the ecu. so it wont help

 

yeah, ecu controls duty and swapping in a b16 ecu for a d-series is not possible so i don't think you can do that for more fuel.

preludes are 290cc 5th gen at least

 

its not to do with the duty cycles, it has to do with the impedance of the injectors. the dual cam VTEC injectors are a higher impedance injector than the D's, but they both flow 240cc. the 4th gen prelude injectors are 310cc if memory serves. 5th are 290 as Kal said

 

ok then explain to me why jdm obd 0 b16s need a resistor box. if they are high impedance then they wont need a resistor box but they do. obd0 are low impedance and require a resistor box, 0bd 1 and up use high impedance injectors so you dont need a resistor box. that should be right for civics and integra, idk if accords or preludes are different

 

*edit* lol yes the obd0 b16 uses low impedance injectors, forgot about that one, thanks man

 

so to answer your question green ex, yes you can use b series injectors but since they all flow the same it wouldnt help you in any way

kal, why cant you use a b16 ecu in his d16 ? ive seen it done on obd1 and obd0 cars. unless obd2 is alot different. not saying this is a good idea but im just saying it can be done

 

well i'm thinking since they're different engines and have different fuel curves and such... that it would not be a good idea. keeping his stock ecu would be better.

 

i have the si ecu in now and a friend of mine used to have one in his ex. ive been told that its better b/c of the fuel. I mean im not expert that just what i heard

Ok well i need more gas to be push in does anyone have an idea of what i should get or do. Im not going turbo or anything just need a little more

 

aftermarket fuel rail, fuel pressure regulator, idk

 

aem fuel rail and fpr is a good combo.

 

if i just got the FPR for now would that push more fuel or do i need to get a rail too?

Um, all 92-00 Civics and 92-00 Integras use 240 CC high impedence injectors, except the CX/VX/(maybe HX), they use 180 CC high impedence. 90-91 Integras use 240 CC low impedence injectors, as well as 88-91 Civics/CRX (only SI with MPFI).

 

Thanks for the info everyone

well then can you explain how im using 99 civic ex injectors on my obd0 ZC?

 

how can you tell the difference?

 

sobe, are you runnin a resistor box with those injectors ?

 

u got lied to! Check the resistance in the injector..ohm it out...let us now.

wait your using an SI ecu in an ex, ahhahahahahahah there are two things that is doing for you giving you shitty gas milage and giving you less power

 

how was i lied to when i pulled them myself? I got the injectors out of a car at the junkyard (99 EX). I am using a resistor box with them and they work fine.

 

how long have you been runnin these injectors ?

 

bout 3 1/2 months

 

i can verify also, i've used 92 JDM OBD1 injectors in my 89 Civic. I also later used OBD1 RC injectors later on with the resistor box with no problems.

the car gets the same gas mileage and it also seems to have a better throttle response so i dont know if its giving me less power
