I have this car I'm working with and has an H23 Vtec with H23 injectors. How much fuel pressure should the regulator have so that it can compensate for the H22 ones?

 

doesnt matter, injectors are to small

 

So definetly they don't work at all? No amount of fuel can compensate the other injectors?

 

sure pressure can compensate some, but overall they are too small.

 

The thing is that the owner doesn't want to change them (cheap bastard), so I have to work with what he is giving me. Anybody know how much pressure to put so that it can compensate almost as the same as the H22 ones?

 

stock is usually ranging from 40-45 on h23s I would personally say to adjust from there and see where it runs the best... Dont you mean H22 ? W/ 23 injectors? or is it a frankinstien? I would prob. set it myself around 50-55... Somewhere in between... But it wont be as effieciant or productive as new injectors... *Plus could cause fuel to leak*

 

I set it around 60 psi-ish and worked fairly good. LEt's see if he decides to spend some money on the other injectors. Thanks!
