Can anyone tell me what size injectors are in what cars-preludes, accords(do they work?), integra, dsm, etc. and if they are saturated or peak&hold. maybe if its a good list it can be a sticky.
heres what i got so far-
http://homemadeturbo.com/tech_projects/dsm_injectors/index.html

Saturated Injectors:

1997-up Prelude VTEC
1992-95 Civic Si/EX
1996-00 Civic
1992-00 Integra LS/GSR/ITR


Peak & Hold Injectors:

1988-91 Civic/Crx Si/HF
1990-91 Integra
1992-96 Prelude non-VTEC
1992-96 Prelude VTEC


1g DSM Non-Turbo 4g63 240cc
2g DSM Non-Turbo Uknown if works
1g DSM Turbo Automatic 380cc
1g/2g DSM Turbo Manual 450cc


Blue tops are 1g DSM injectors, and black tops are 2g DSM injectors

damn !! beat me to it .. lol .. i was just searching the web for an Injector cc chart !! nice find Dog !

now heres a question ... what the difference between ' peak and hold ' and ' saturated ' ??

[DOG]

Peak and hold is the OBD0 (pre-OBD) low impedence injector type which needs the resistor box in order to recieve the correct voltage.
Saturated is for OBD1 & OBD2 systems which do not need the use of the injector box.

You can use Peak and hold injectors on OBD1&2 systems if you use a resistor box.
You can also use saturated type ijectors on OBD0 systems but you need to reove the box.

All that right or did I miss something?

[2redstars]

now do all of those work on civics?

[DOG]

I would say yes but I dont have any first hand experience except with the Honda/Acura injectors. However I believe they do. Some of those seals may need slight modification as shown.

Ok, I`ve lurked long enough...

If 92-95 si/ex injectors are 240cc saturated...then what are stats for 92-95 DX/LX injectors (d15b7)? I`ve scoured the net looking for an answer and found nothing.

(I`m assuming they are the same but that`s probably wrong)

<edit>

According to accel`s fuel injection page 1992-1995 ex/si/dx d15b7 and d16z6 both flow 235cc saturated (so I answered my own question).

[DOG]

You are correct sir. 92-95 dx and ex flow the same.

Injector size info
-------------------------------------------------------------------------------
http://www.honda-tech.com/zerothread?id=373764
You can go with any size injector that meets your HP goal with a standalone. And as long as you aren't running the injectors at really high duty cycles you are fine too.

Here is something I posted up on po.com a while back, it tells us what the various HP limit is for a injector size. The HP numbers are for stock fuel pressure, and 100% injector duty cycle, I suspect that they are a bit off so dont use it as a solution to your problem. I would still take the injector size and ask around to see if they are the right size.

EDIT: by raising the fuel pressure you can get more fuel from the injectors, and remember since the HP numbers are for 100% duty cycle, you should select the next highest sized injector for you HP goal.


270cc = 187 HP
310cc = 214 HP
320cc = 220 HP
370cc = 256 HP
400cc = 277 HP
440cc = 304 HP
450cc = 311 HP
500cc = 346 HP
550cc = 380 HP
600cc = 415 HP
650cc = 450 HP
800cc = 554 HP
880cc = 609 HP

Thanks 2redstars for the info and help. Very cool. 8)

I've a question here: what about the injectors of the B18C? I'm using it now for my SOHC engine.

[DOG]

"Honda usually runs their injectors to 100% duty cycle at redline. They appear to adjust the fuel pressure to achieve this. A good example is the early B16A and B18C engines. Both have 240cc injectors, but the B16A has 38 lbs fuel pressure and the B18C has 45 lbs fuel pressure."

[FMYStreetRacer]

is a 92-95 prelude obd1? it says up there that the injectors are peak and hold.

[DOG]

It does look like there is a problem there. Ill see if I can find out tonight.

[FMYStreetRacer]

thatnks it would be a huge help to me.

[bigmrg]

over here in the uk honda worked with a car company called rover suppliying them with the whole drivetrain stuff so can anyone give a injector chart with injectors matched to engine types as in the rovers they are using f22 and h22 engines amongst others this would be a help to us euro's when scouring the breakers yards

[DOG]

Ill see what I can find out for you. Give me a day or so.
