    f22a1/h23a1 headswap

    i know yall got threads for days about the f22/h23 headswap on my 1990 accord, but ive been searchin around for a month and i cannot find anything concerning the problem i am having to complete my headswap...i have an f22a1 block with an h23a1 head.. im not totally sure what distributor i have to use... i have an h23 external coil distributor, my friend told me i can rewire the external coil distributor plug to work with the f22a1 harness, ive gotten the majority of it rewired except for one wire. i wired the black and yellow with the matchin wire and blue with its matchin wire... the only wire i have left is the yellow wire...i tried wiring it together with the black and yellow but it didnt start up... keep in mind my distributor is external and the accord is originally internal...would i need to get an h22 distributor...or is there a way to rewire the distributor.... and would the h22 distributor plugs plug up with the f22 harness... my h23 distributor didnt plug up with my f22 harness so thats why im tryin to rewire this thing...any help would b greatly appreciated

    So basically what you need to do is find information on doing an internal coil to external coil conversion...

    http://www.cb7tuner.com/vbb/showthread.php?t=84028 Might help a bit.

    Don't concern yourself with the fact you did a headswap... it's just an internal to external issue you need to fix.


    Now, I hope you did the proper modifications for the rest of the headswap!

      ok thanks for the link...but im not understanding how that is gonna help me much... my car is originally internal coil....that is for an external coil car to remain external, while using an internal coil dizzy.... i have a car with an internal coil and im trying to make it external

        hey bro, I have the same set up - an internal f22 with an external h23 dizzy. From what I have read and understood, if you take everything out of the h23 dizzy, except the long shaft, and then take the same stuff out of your internal f22 dizzy, then put the f22 internal dizzy's "guts" into the h23 external dizzy, it should work. Since your car is already internal coil, you don't have to worry about the fifth sire off of the cap. I also heard that the internal, cap can fit on the external dizzy. Don't know about the rotos though. I don't know if the f22 internal rotor will fit onto the h23's shaft, or if the h23 external rotor will fit under the f22 internal cap.

        does that make sense? I sure hope so

        ^^click it or ticket^^

          try d112crazy's advice on that same thread



          ok.

          Another way to do, which requires no cutting or splicing of anything, and keeping the internal dizzy, but its converted to external.

          First thing that should be done is to make a reference mark on the cam side of the dizzy. Be sure to put everything back the way it came off.
          Take off the o-ring with some pliers, and take off the rotor and washers. Set them aside where you won't lose them.

          Take off the dizzy cap, rotor and dust cover. start taking off all the screws you see on the top part. Make sure you don't lose anything. Once you get the top half loose, move the plate to the side and remove the other screws(should be 4 of them) on the lower part of the distributor.

          Now, pull out the distributor guts.

          Do the same thing to your stock f22 external distributor.

          Install the guts of the f22 dizzy with all the correct screws into the h22 housing, with the h22 shaft/plate.

          Install and align the washers/rotor and put on the o-ring.

          Reinstall the h22 cap/rotor. and now you have a usdm h22 distributor.

          Sorry for whoring your thread.

            aight guys.. thanks for all the help... i understand what the diy is saying now... i took out the grommet out of the plug and the solid yellow wire that was hanging loose from the external coil i plugged it up to the empty space were the grommet was. i made sure that it stood in place then i connected the plugs back together...the solid yellow wire looks like its plugged up to the solid green wire now...i tried crankin it up and still nothing.... oh and i understand what you're saying about swapping out the guts... but the thing is i dont have another distributor this is all i have

                did you check for spark? you make sure your timing is set correct?

                    check whether you have spark or not by removing a spark plug wire from the spark plug. have an assistant put a screwdriver in the wire and place it near a ground, body of the car. then crank the engine there should be a spark jump. if have spark you need to check the timing its possible you put the distributor 180 degrees off. you can still do a close timing without a timing gun. remove spark plug from cylinder 1 (farthest from the distributor) put a long screw driver down the spark plug hole. now turn the bottom crank bolt to turn the engine. there should be a hole in the splash guard for that behind the drivers side tire. it will start to lift the screwdriver up. wait till the cylinder is at its highest position before the screwdriver starts going back down. this is TDC. you should also notice that the mark lines up on the bottom crank. look at distrib cap look where the wire for cylinder number 1 goes. mark the outside of the distrib where the cylinder 1 wire lines up to.take the distrib cap off look where the rotor is facing. it should be pointed at the mark you made for cylinder 1. if not like i said the distrib might be 180 degrees off so pull it off and adjust the rotor so it lines up to the mark. not perfect timing but it should run




                    peace

                        it is timing.

                        code 15 is the igniter. You fucked up the wiring, some how.

                        Pictures of what you cut would be helpful.

                        i have a feeling you cut the wrong wires.

                              First off, I suggest you rewire the stock plugs in their stock locations. There is no need to switch plugs. They all fit.

                              Since you need the h23 dizzy, you should have either swapped the INTERNAL wires/plugs, or ONLY splice the yellow/black and yellow wires.

                              That's it.
