Its been a couple of months since I did my swap (JDM H22) and ive had nothing but problems ever since. At first i was throwing a couple of cels and the motor would run hella choppy. I was running a p13 4ws ecu that steve at Hmotors sold me. I swapped back my orginal p14 and dam the car runs like a champ (no vtec though). I put the p13 and then runs like **** again. Im stumped and I dont know if it is the ecu or the wiring.

 

Sounds more like someone forgot to switch over to the H22 injectors.

 

I still have the original injectors... hmm that might be culprit

 

You have the injectors from the H23 on the h22?
Almost 100cc diffrence on those injectors. H22=345cc(obd1) H23=240cc

 

Dang!! not my fault it was the stupid *** that did my motor swap!!

 

Lol, that would explain why the p14 runs the motor better

 

Cool sounds good now I know what I gotta do!!

 

Is the fuel rail the same in the H23 and in the H22?

 

Yes just the injectors need to be changed

 

Wrong. The fuel rail on the JDM h22a is reversed compared to the h23, due to it coming from a right-hand drive vehicle.

So unless you want to completely re-route your fuel line to come from the left side of the engine compartment...use the h23 rail with the h22 injectors.

The engine is already in the car brosef. It is most likely, as well, that if the mechanic left the h23 injectors in there, the h23 fuel rail was also most likely re-used.

 

Yes I do believe I have both the H23 fuel rail and injectors. I have the H22 rail and injectors and im just gonna take them off that rail and put it on the 23 rail
