Stock, Honda injector sizes

[TheChosenOne]

I was wondering if there are differences between single cam injectors and dohc injectors.

I know this is prolly a noob question, but I am just wanting to know if putting B16 injectors in a D15 would help out with a Walbro fuel pump.

you would need to tune it. Or get it adjusted correctly so a fuel pres. reg. would be good to have too. cant just run it straught up. Also the b16 injectors are a bigger cc than the d series.

Yea... that's what I was wondering. I know I have to adjust the fuel pressure, I just wanted to know if the cc's were larger on twin cam motors.

all b and d series are 240cc w/ the exception of the non-vtec d-series which are 180cc. h series are a different question up to 345cc for the jdm engine.

Thanks everybody... so I guess stock prelude injectors will safice when it comes to all motor builds then?

[scttydb411]

yes, the usdm prelude injectors are smaller than the jdm ones, but bigger than stock civic injectors. i think they are 280 or 290cc.
