Difference in CC? Same dimensions? Any help appreciated.

im pretty sure all b-series motors use the same injectors.. 240cc if i remember correctly.

Fairly sure this is right also

Wouldn't 240cc be quite small for a B18CR?
What does H22A use and are they the same?

Honda run their injectors to 100% duty,so they prob seem smaller than most,I dont know what others use...

I think the H22's are something like 310cc

B18CR are 240 CC same as per B16A

The difference is in the fuel pressure

I dont know the exact figures,Im a net mechanic,but they run them close to 100% at peak rpm,whereas Ive seen others like to stay below 80% I believe.So prob hard to get much more out of a stock injector I pressume,only adjustment being pressure?

Ive seen 94% so far on mine.I actually got worried & installed a better pump before I knew this,but I gotta drop the whole tank out to change it so stuffed if I'm changing it back again.My duty has dropped about 10% on average now & I'm still yet to work out whether this is a good thing or not yet.Maybe you can enlighten me? All I know so far is I'll prob get less accuracy out of milder loads or something like that,cause of the lesser range of duty I'm playing with??

does htis mean that all B-series fuel pumps are the same to?
is a D-series fuel pump sufficiant for a b18?

Like I said,I'm no expert,but I'd quite happily put my D16 pump back in tonight to supply my B18 if I didnt have to drop the whole tank out to do it.Its a lot quieter.

If the fuel pump can supply enough fuel to maintain the fuel pressure the regulator is demanding, then all is fine.
