they are honda IPT 4006 they were on the motor when i got it.
My tuner was curious to see if he can make them work thanks.


Maybe this will get more attention here.

- Tue Mar 31, 2009 7:08 pm #106908 AEM has them down as 240CC, same as B, H, D series VTEC. But they're 2 Ohm, so you're going to need a resistor box.

Don't read too much into stock injector sizes with Honda. They use the same size injectors on every engine. The trick is that they vary the fuel pressure.

Early F series non VTEC engines are the best flowing 4 cyl engines available to us. The only problem is that they don't quite fit under the hood when swapped into our chassis. That and the stock tranny gearing sucks. However, Bisimoto seems to have developed this engine into the worlds fastest SOHC.

- Wed Apr 01, 2009 6:06 pm #107363 I don't count propping up the rear of the hood as "fitting". Or cutting the hood and putting in an Eclipse style hump.

I don't know much about it, but from what I can tell, in the Accord the engine leans way back. When you try this in a Civic, either it doesn't fit under the hood, or you have a bad angle on the axles going into the hubs.

But if you know something I don't then just ignore me...

now why the hell would a d series have 240 cc's, theres no way that the h and the d have the same cc injectors, im gonna have to call honda on this one...

HONDA OF AMERICA service center FTW!

Why the hell would Honda engineer a different injector for every engine they make? :wink:

- Thu Apr 02, 2009 10:25 am #107669 the litre size of the engine.. by dump the amount of fuel a h22a4 uses into a d15... honda makes there engine better than anyother company out there, they are not a car company, there an engine company.

thats why there are differnt DSM injectors. there are 390cc dsm, and 410cc and 450cc injectors.

on a factory maped ecu it is spec'd out to discarge the proper A/F mixture.

i just got off the phone with honda and

most b sers are 240cc along with other honda engines. but there are some differnces

heres a list of what ive come up with on injector sizes from honda.

Call Honda. D16Z6 injectors are the same as OBD1 B series injectors. D16Y8 injectors are the same as OBD2 B series injectors. Oh and guess what? The Acura NSX... yep, 240CC.

Not ALL of them are 240CC. Non VTEC SOHC are 190CC. H23, newer Civics, and the RSX are all 330CC.

Injector size by itself doesn't control the amount of fuel flow. It limits the maximum and minimum amount of fuel. The amount of flow is controlled by fuel pressure and injector pulse width. That's basic knowledge. But call me out on it so more so we have more to laugh about later. Maybe you should stick to DSM's.

- Thu Apr 02, 2009 5:08 pm #107734 Also neglected to mention that every time I get a new engine, I get the injectors balanced and blueprinted. I have a print out from RC Engineering proving my D series injectors are 240CC.

That reminds me to point out that injectors rarely flow the amount that they are rated at unless you've had them serviced. Even brand-new out of the box injectors don't flow as well as balanced/blueprinted injectors.

People ask questions because they are unsure,looking for clarification. it is totaly unecessary to be-little people for what your own pleasure?? expect that on honda-tech but here.. fuck you man.
