Vti fuel injectors vs Vti-R fuel injectors

[Terry]

Hello people, is the vti fuel injectors is the same as Vti-R? If swap the Vti-R fuel injectors to a vti would that be any good? any help would be great!:D

PS: right now i got CAI and full exhaust.......so i wonder VAFC and Vti-R injectors would do any good for the SOHC Vti civics.

they have different cc rating I recon

your engine will run shit, you will need to retune your ecu

jack shit difference. d15b sohc vtec injectors vs b16a dohc vtec injectors... doesnt do any difference.

a) I hope English is a second language - I've read this post 3 times and barely have an idea what you mean :(

b) Why are you doing it? Don't expect a power increase from the swap without other big-time mods - assuming you are asking if swapping them will net you an increase.

Given the compression ratio remain unchange, can i get more HP from my Vti engine by improving the air intake and fuel supply?:confused:

Your stock injectors are plenty enough for all the air intake mods you could ever do other than fitting a turbo.
Once you have done your intake and changed injectors you would still need to retune your ECU.

[sivic]

absolutely ZERO point in doing it.
your mods nowhere near warrant fuel system mods.

are they even different? I don't know what engine comes in the Vti versus Vti-R, but I do know out here everything from the d15b7 to the b18c5 come with the same cc injectors... difference is in fuel pressure and fuel mapping

saxman: vti here in australia has the D16Y8 engine and vti-r has the b16a

then the injectors are the same

No. You will not benefit by changing your injectors.

you want to reduce fuel delivery, not increase it to gain performance from those mods.

more fuel with this setup will actually make you lose power....
A petrol engine requires more air to make more power
