Fuel Rails

[imashy14u]

Hi,

Just wondering how much extra flow does the fuel rail of a DC2R compare with a B16A and a D16Y4. Is it a lot different between the three??

[bennjamin]

the fule rails size and cc/minute flow rate etc arent so relevant to the engines flow of fuel - its the very injectors themselves which directly control it.

If you want more fuel into the mix get bigger injectors , and a ECU to control them/make them worthwhile.

b16 and b18 have same size inj

the d series rail and injectors are smaller and flow less than the b series

[ECU-MAN]

flow is regulated by the fuel pressure regulator. at the end of the day you can put a bigger rail but if fuel pressure and injector duty cycle stay the same there will be no advantage

Tanghy I assume you are correct but Honda say the injectors are two very different units.

My little question is will my B16A injectors feed a JDM B18cR ?

Im confused ..

Putting larger injectors/fuel rail won't do anything unless you have an ECU to alter the duty cycle!

[Civic Type R]

would a Mugen 'race only ecu' qualify the necessity of larger injectors over the B16A ones ?

[poid]

you need to use the injectors that are the size the ECU is tuned for if you wanna do it properly

As above!

how come no one has suggested getting bigger fuel pump?

You don't need a bigger fuel pump for N/A. The stock one will be able to cope with gay N/A power.
