fuel injector

[G&M motorsports]

what are the stock fuel injector cc size out of f22a1 and what would be one size bigger and where can i find or buy new one's i have the a6 intake with the butterflys removed so i think i need more fuel....... help......

[ExplodingCake]

No you don't. Stock ones are fine. IIRC they're 235 CC.

my manifold was red hot after i ran it hard and someone said that it looks like i'm running it lean and i should look into getting bigger injector thats why what would you do

[tommi]

correct me if im wrong but bigger injectors wont help u none. since the ecu governs how much fuel air to mix. even if you were to put bigger injectors in. the fuel pump is only gonna puump out what it was designed to pump. unless u go walbro. and get a tuned ecu and rc injectors.

Tuning the ECU will correct a lean condition. The injectors flow fine for a lightly modified engine. Larger injectors will only confuse the shit out of the ECU, potentially causing even more damage.

You might want to have your injectors professionally cleaned and balanced.

just because "someone" said you might be running lean does not necessarily mean you are. there are plenty of people who have no clue what they are talking about. not saying this guy does or doesn't. i'm just saying be careful whose advice you take especially on something as vital as fuel injectors.

I thought most Hondas were 240cc minus the NSX and Prelude which were 270cc?

I take it your talking about your exhaust manifold? If so, is it a cheap Ebay header? Cheap ebay headers will do this cause they are like paper thin.

If were talking about the oem cast iron manifold, you might have a clogged cat or bent exhaust causing a restriction.

This is of course if the exhaust manifold is actually glowing red hot and someones just not talking out their ass.

A wideband A/F meter will tell you if you're running rich or lean... it's a much better tool than "someone".

98 crx and civic del sol are the only hondas i know of runin 240cc most others run 235cc just like the cb7

Here is a list I was emailed from a local engine shop that cleans, services and flow tests injectors.

1988-'91 Civic Si/CRX Si Peak and Hold 240cc
1992-'95 Civic Saturated 240cc
1996-'00 Civic dx cx and lx Saturated 190cc
1996-'00 Civic ex/si Saturated 240cc
1990-'91 Integra RS/LS/GS Peak and Hold 240cc
1992-'00 Integra LS/GS Saturated 240cc
1992-'96 Prelude Non-VTEC Peak and Hold 240cc
1992-'96 Prelude VTEC Peak and Hold 345cc
1997-up Prelude VTEC H22 Saturated 280cc
1990-'93 Accord Non VTEC F22A Peak and Hold 240cc
1994-'97 Accord Non VTEC F22B2 Peak and Hold 240cc
1994-'97 Accord VTEC F22B1 Peak and Hold 240cc
1997-'02 Accord VTEC F23A Saturated 240cc
2003-'07 Honda Accord 3.0 liter V6 Peak and Hold 240cc

Why split hairs between 235cc & 240cc it's 5cc's. Big thing is the impedance of the injectors and the drivers that are being used to control them. As well as the fuel pressure. Fuel flow, as in a walbro 255lph fule pump, does not change the amount of fuel flowing through the injector. However, increasing and/or decreasing the fuel pressure will.

In the current case one would need to know what type of manifold is being used. I had my header (18 guage SS) glowing red hot and my AFRs were a stock 14.7:1. I agree that a wideband O2 is a reliable way to scan your AFRs. You could also pull a spark plug and see what the tips look like. If you are running lean they will have a white dust covering the electrode and ground strap. Worst case they will have already started to melt/burn up.
