well they are different according to honda. do a parts number check they are different so yes its safe to assume that y8's are bigger than y7's and y7's and y5's have the same part number too

You say maybe the y7's just didnt work.

How is that possible when they work with the stock ecu fine ?

I know the chip ran extremely rich on my car, and on his too.

That might play a part in why they didnt work withthe chipped ecu.

I just found out: All 6th gen civic injectors are 240's.

ya'll can stop bickering now.

I looked in the helms manual for damn near an hour and couldn't even find out looking in there. Luckily, last night I was thumbing through some old Honda Tuning Magazines and found an article about fuel tuning and the injector size was mentioned there.

The article was written by somebody from RC Engineering so I can trust that.

D16Y8-Z6

Info from a good source.

But maybe Ill send out a extra set of y7 injectors to RC to get flow tested.

Just to double check.

Some things just DONT ADD UP.

I can't believe I couldn't find the damn info in my Helms manual. I mean..it is a large book to look in but I combed the fuel section pretty thoroughly twice and didn't find the injector sizes.

If anybody can find this and point the page out to me that would be cool. Feel free to call me a dumbass if you can find it.

y7 injectors are 190, arent the ex injectors bigger since its vtec?

stargazer

Yeah dude...the Y8 injectors need to be 50 CC larger for that other 21 HP the EX has over the DX/LX.

They are all 240 CC

projekteg

all civic and itegra injectors are 240, that's sohc, dohc, vtec, and non vtec

this shoulda been locked (i know u dont lock this ----) when this was posted

i dont see how this can be true if you go to your local honda dealership or www.hondaautomotiveparts.com you will find between the engines the part numbers are different for the injectors. why would honda make different parts if they produce the same results?
