injector size

[CB7lx91]

I'm doing the head swap, so I figured I'd check out aftermarket injectors for the hell of it. Are they worth it? and what size should I go for? I heard if you go with a larger bore injector you should get a bigger fuel rail.

not for a head swap the stock injectors are fine. the h23 takes the same size injector as a h23. without tunning that is just retarted

Do you mean "the h23 takes the same size injector as a f22."? if not, then i am confused

not worth it or even remotely necessary.

yes, i was told that my injector is the same as a h23, i have the f22b2. all f22 's should be the same the only injector that is bigger on a stock honda is the h22 injectors i think.
f22 injector = 355cc
h22 injector =450cc
or something like that. my point was stock injectors are just fine unless you have some serious mods (usually only for turbo).

f22 an h23 are the same

The headswap itself is going to give you more of a headache than it's worth... I don't know why anyone bothers. It's the most worthless thing to do to an F or H series motor. You didn't even specify which head you're using.

You don't need larger injectors until you're making considerably more power.



Also, please resize your sig, or you will lose it.

If I'm not mistaken, the f22 injectors are 230cc and the h22 injectors are 330cc

[deevergote]

OBD1 H22 is 345cc peak and hold
OBD2 H22 is 290cc saturated

Since the OP didn't specify what particular head he is planning on using, there's no point even putting that much effort into a reply.

Those injector sizes sound alittle high bro..The F22a I believe is 240cc and the H22 injectors is I think 340cc if Im not mistaken.

[deevergote]

Yes, the F22A injectors are 240cc. The H23 injectors are the same.


It's sad how much terrible misinformation is being given in this thread. The people helping the OP are as clueless as he is!
