ok so i have a 93 civic with a h22a4 and the motor is blown, i just bought a 94 f22b1 sohc vtec and am goin to swap it into the civic, i already know that my motor mounts, tranny, clutch/flywheel can be swapped from the h22 to the f22. what i dont know is if the wiring is goin to be the same, am pretty sure a lot of it will work. does anyone know anything about this swap.. thnks

 

IT sould for the most part plug up but I think your intake air temperature sensor will be on the manifold instead of the intake pipe.

 

doubledeucehatch are you going to respond to any of my pm's???

 

there is another two wires at the ecu that has to be swapped back. when the h22a was installed they were swapped.

i forget which ones they were of course but i learned this the hard way when i had a h22 in my accord that i put back to f22 to sell and i ended up selling it with a CEL because i didnt swap the two wires.

 

What 2 wires?? I havn't had to swap any wires at the ecu when swapping an H22 into a civic??

 

the H22 and the F22 dont use the same mounts.. how ever why are you swaping an Fseries in a civic? it doesnt make sence to me.. what harness are you using the H22 or F22?

 

the f22 and h22 are the same mounts, i did this same "swap back" about 9 years ago when my H22 spun a bearing. i used my same wire harness as i used for the H. i never had a problem at all except the fact the F22 sucked *****.

 

oh my bad bout the mounts.. its not the same for accords

 

o blown okay i was about to say why downgrade lol =]

 

if the OP is using a 94/95 Accord ECU (P0A/P0B?) he would need to swap pin A6 with A11 on the ECU harness. this is necessary since the 5th gen was wired opposite of the 4th gen for these two pins. these were EGR and O2

ah..i got goofed..OP said f22B not f22A. carry on
