would ITR fuel injectors make a difference on a b18b1?

 

Depends on your setup. If you're running lean, you may want to think about it, but you'll end up too rich if you just want more fuel.

The fuel system is special in that it all needs to work together. You can get an intake and it will help your hp gains, but if you just add more fuel, you're going to make things worse (depending on how much you add).

 

arent all B and D series injectors the same?
as far as i know the injectors in a civic vx are the same as in an integra type-r....all are 240cc...
i know inspyral posted similar #s as well a while back

 

All B series are 240cc's

All D series are 240-cc's

92-96 H22a1's are 270cc's

97-01 H22a4's are 290cc's

H22a1 injectors are a bolt on affair for all b16a2 fuel rails, all you need to do is lengthen the 3rd and 4th plugs


Cool huh,so no it wouldn't do you any good.

 

actually 92-96 h22a injectors are 345cc....least that is what RC says...i got 3 sets of em

 

Isn't that what RC can make them?Are you maybe talking about the H23A or A1 or the H22A1 from 94-96,or I am I getting owned?Also the is a 50cc jump between the B and D 1.6 to the 2.2l H series I don't see the need for such a big jump for .1 liters.

And another thing rc doesn't have 345cc injectors

But this is just their website,it could be wrong.Meaning they might not be listed don't get in a twist.

 

i think the h23a1 is the 270cc, i know h22a1 is either 320cc when measured at 85% duty cycle or 345cc when at 100% duty cycle.
the vtec cams on the h22a are a lot of lift....i know the fuel maps for the p72 ecu cant really handle the large injectors and cam lobes til high rpm...

 

If your B18B injectors are dirty or clogged, then newer ITR injectors might make a difference. Otherwise, they flow the same amount.

 

You can have your injectors cleaned fairly cheaply ($50) if you are concerned about them.

 

good to know.. thanks!
