i need the wiring harness for it. i have everything else.i have an engine harness for it. missing 2 or plugs. u can get them off your old harness. $20

im not sure but i wouldnt think they are any bigger than what your running now.


edit: they are bigger i had to do some searching

h23 are 240cc
h22 are 345cc

[bpoweredhatch]

h22 injectors are bigger then h23 injectors i ve been told a few times

[h23bb2]

h22A1 USDM= 330CC OBD1
h22a4 USDM= 280cc OBD2
h22a JDM= 345cc OBD1&2
h23a1/3 USDM= 230cc OBD1&2
f22b JDM= 230cc OBD1

Hope this helps

[Romeo]

So your putting on a h22 injector on a stock h23 motor?? Why would you do that.

no. the motor isn't stock. that's why i want a bigger injector.

[DarKStaR]

whats up, the h22 injector is bigger....BUT it should still flow about the same until you get it tuned or turn up the fuel pressure

unless you're tuning for it you shouldn't swap injectors unless you're wanting to run rich for some reason.

the injectors will either be the same or 2 chances to be larger:
240cc
280cc
345cc
it depends on if the h22 is auto, 5 speed or jdm 5 speed.

100% agree!!!! your H23 doesnt need the H22 Injectors unless your Boosting NOW, if its a N/A car leave your H23 injectors it will run better then those H22 unless your getting it tuned!

When I say getting tuned I dont mean in about 6 months from now after you install them I mean NOW before you crank it up!

I know him. He won't do it and not get it tuned. He'll have everything done the right way the first time.

why thank you tyler. haha. but i was wanting to run them because my motor has some stuff done and i figured the bigger injector would help it out a little.

only if you tune for it...sounds like you will though. depending on what you have done to it you may still be ok w/ a stock injector unless you're pushing signifigantly more power.
