Can anyone tell me what other engines injectors are compatible with a H22a with a P28 ecu

 

You want an OBD1 Peak & Hold Injectors, these are 345cc.
Not the saturated OBD2 that are 270cc or 290cc, can't remember exactly at the moment..

Is the P28 you're using Chip? Does it have an H22 Base Map?

 

I have hondata

 

What's wrong with the 290cc/min 5Gen injectors? I made 204WHP with them without any problems at all.

If you use the P&H 4Gen injectors, you need to make sure you use the ballast resistors. With the 5Gen injectors, you don't need the ballast resistors.

BTW, I use a P28 with NepTune RTP.

 

^^Yea, what he's running and what they're in, being used with would help alot.

So would you like to give us more info, please?

 

Ok here is what going on. I have h22a not sure what year, turbo charged, 750 cc RC injectors and i have hondata s300 that I have not tuned yet so the car deos not good or practically at all because it's getting to fuel so i would just like to know what other engines injectors would be compatible with the h22 and the p28 ecu which i am assuming is just tuned to stock, because i had a accord h22 turbo and i took the stock injectors out of that car and put them in this one and it ran great. so i just need to know which injectors weather it be d series, b series, f series, or h series if there is anyone that can help i would really appreciate it thank.

 

Most of the Honda injectors, or any injectors pretty much don't have much of an issue plugging in. Alot of injectors are designed to be universal.

It sounds like you are over thinking this too much. If your running an OBD1 car, and you want to run a stock H22a, just run a P13, with the 345cc injectors. Anything other than stock sized injectors will cause issues. Smaller injectors will run leaner in the higher RPM's. Bigger injectors will run richer.

 

yeah i know i dont have smaller injectors so im asking because i am going to buy some i am wondering if they have to be from an h22 or will others work

 

What year car is it in? Does it have a Resistor Box?

If it's OBD1 with a Resistor Box, run 345cc Peak & Hold Injectors.
If it's OBD2, not Resistor Box, run H22A4 Saturated Injectors.

I don't know the Specs to other engines injector ratings.. So I don't know what would be similar. I'd recommend running a stock injector from the H22 anyways.

 

you said the car has a turbo, and not tuned..... is this a project car just getting finnished? you might want to think about tuning the car befor you buy more parts, exp stock injectors. i still have the stockers out of my h23 and the box for them. when i turboed my lude the stock ecm ran the car beter then the hondata one did, but it was very lean! now im not say'n you dont need smaller injectors, im say'n get tuned and go from there. you just might be lucky and be good with what you already have.

 

I have the engine in the a right hand drive crx and yes it's a project the only reason i want stock injectors now, is because i want to be able to drive it to the dyno to get tuned but i cant do that with the larger injectors. All i want to know is what injectors from other cars or engines are compatible so i can go to the junk yard and get some because the car runs fine with smaller injectors but i could not find any h22 injectors for cheap so i was wondering about other injectors and the engine doesn't have a resistor box
