no they are prolly not, the average person on this forum thinks that every honda/acura injector is 240cc/min but the fact is that on the d series honda i believe that those injectors are much less as in 170-180cc/min, its been tested

If its been tested how come you believe. I have never heard of a 170-180cc injector. The only 190 honda injector i heard is obd0 injectors. All other B and D are 240cc then H, F, K are different. If its been tested show the test results.

Yup, 240cc Saturated. used my VX injectors on my Z6 motor when it was in my car, didnt have any problems for 14 months b4 i went DOHC. Now if was the smaller injectors, as some of the recent talk on this forum, the motor would of ran lean and seized up, but it didnt

you should prolly check out the service manual for a 97 cx then, it clearly says that they use 190cc injectors

this is how misinformation spreads. There is no factual bearing that all honda injectors are 240cc, look at the d16y7 for example.

i believe the vx and cx injectors are the same size and I have always assumed they are smaller than 240cc

lol I'm so sick of this debate. Since I have a set (refer to sig ) someone want to tell me how to test them?

Like if I put them in on a stock B16 will it run all fucked up?

figured this might help someone out later on. vx injector size is NOT 240cc if you put that big of injectors in the z1 motor stock it will cause (as it did on mine) to throw a code (s). the proper injector size is around 190cc and a good way to tell what your injectors are is to check the injectors, and on the side of the injector there are four circles 0000 in the first circle there is a 5 then the next two are blank/empty and the last circle has a 5 so it would be 500A
and so there is proof once and for all here is a print out of a flow test done on the injectors. i have seen some others flow tested and they have been 185cc and running fine. but no where near 240cc like most of the community believes.

From the list at HAmotorsports the VX should be 240 (235).

The only motor from the 5th gen that was 180CC was the D15B8 USDM CX.

Code:
D16Y7 1996-1997 Honda Civic CX,DX,LX SOHC 16V I4 180 
D16Y8 1996-1997 Honda Civic EX SOHC 16V I4 VTEC 240 
D16Z6 1992-1995 Honda Civic EX,Si SOHC 16V I4 VTEC 235 
D15B7 1992-1995 Honda Civic DX,LX SOHC 16V I4 235 
D15B8 1992-1995 Honda Civic CX SOHC 8V I4 180 
D15Z1 1992-1995 Honda Civic VX SOHC 16V I4 VTEC_E 235 
D16A6 1988-1991 Honda Civic Si,CRX Si SOHC 16V I4 235 
D15B6 1988-1989 Honda Civic,CRX HF SOHC 8V I4 180 
D15B6 1990-1991 Honda Civic,CRX HF SOHC 8V I4 235
So if that is erroneous info it's pretty common misconception at most databases.

On the plus side, you know you can rob the USDM CX for it's injectors if needed in the future.

Did you notice any improvement in MPG with the injector cleaning? I've been debating whether or not to have them serviced, but not really sure if it's worth it.

ya cx parts are also easier to come by. so far only other thing i have noticed that is compatible with the vx is the injectors and throttle body. i read a thread once on ecomodder that the cx injectors have a different spray pattern however i can not verify that rumor though.

I can confirm that the CX/VX injectors are 190CC and all the others are 240CC.

Had mine done at Injector Rehab. Good people over there.

Didn't even think of checking the OEM parts sites.

^^ I had a tuner try to tell me my 190cc injectors were 240cc.. We swapped in a set of y8 injectors and the car ran rich. I don't know why its a debate when so many people have done manifold swaps(y7 to y8) and point this out. Cx/vx Same injectors

Just for clarity.... USDM CX and all VX have same injectors.

Canadian CX has the 240CC injectors and do not share the same part numbers as either USDM VX or CDM VX.

USDM CX's are a rare breed in Canada, even rarer than the VX is in Canada. This is a nifty trick for those in the states.

Would hate to see some Canadian VX user read this thread and go off running to a salvage yard to grab CX injectors and then cause cylinder wash from running the car too rich.

yes i should have clarified that. good catch

i am also tired of hearing people tell me when i am looking for parts for my vx that ALL 1.5 d series will work. my vx i recently bought has a ex manifold on it with 240cc injectors. just a headache.

Yeah that could get old pretty quick.

You can always use the OEM parts sites to compare parts between trim levels to see what is the same and whats not. It's pretty handy that way in my opinion.

Confirmed that that part number is shared with USDM 92-95 Civic with the D16Z6, D15B7 and is 240CC
