    Head/Intake swap f22a1

    So I'm getting ready to do a head/intake swap on my f22a1. the intake manifold is from an h23 and I've got a 68mm throttle body. The head is from an F22a1 but I've cleaned up that ports, polished the exhaust and lapped the valves. I've got all new gaskets and o-rings and a delta ground 272 cam to install.

    What I'm wondering is if there is anything I should be prepared for or look out for. Do I need a special grease or sealant? So far the only thing I think I've missed is the Dowel Pins, which I will hopefully get today or early next week. I was planning on assembling everything to the new head and then swapping it over as one unit. Would this be a good way to do this?

    I have my Haynes Manual and the internet so I think I should be able to succeed, but I am pretty new to car mechanics and this CB7.

    The Haynes manual is pretty basic. Might be enough for you, but I'd strongly advise getting a Helm manual, which is the official Honda shop manual. Everything you need to know is in there. What tools to use, torque specs, part numbers, etc...

    You can even download a digital copy of it in the Files section of the CB7tuner Facebook group (which is a pretty terrible place, to be honest... but the file can be hosted there without any real issues... whereas I won't host it or link directly to it on this forum.) Still, a hard copy of the book is far more useful than a digital copy!

      Hopefully, Delta sent you some cam lube. If not, you definitely need some. And Web Cam wanted me to keep the engine rpm above 2000 rpm for the first 20 minutes of operation.

      You also might want to take the rocker arms apart and clean everything up and relubricate.

        Should he be using F22A6 springs with a more aggressive cam?

          I was wondering about the springs too but according to Delta, the stock springs are fine with the 272 grind.

          Also, my local auto parts store didnt have "cam lube", but in the haynes manual it says the moly lube can be used, which I have.

          I downloaded the manual from the facebook group page but its missing the index! does anyone have the index pages? It's tough to search through a 1000+ page PDF that you can't use the search function with.

            I used assembly lube when I installed my 272. Also, during the "break in" process, not only do you keep it at 2k for 15 mins, you need to have the valves at .008 and .010 before you go to the recommended .006 & .008.

              Web cams wanted me to use 0.007" for intake and 0.008" for exhaust after the initial breakin.

                Thanks for that! Hopefully I will get my dowel pins early next week and will be able to put this all together.

                Tomorrow I will be assembling the head, all my parts a ready.

                One thing is, I haven't ordered my sensor and ostrich for my P06 ecu yet so I wont be hooking up the IAB's yet. Will I have any problems with this? Or just less power at low RPM?

                  No problem. You can run a vacuum line direct from the intake manifold to the IAB control diaphragm for the time being. It's not ideal, as the secondaries will open at WOT at low engine rpm and you will lose some torque/power. But they will at least stay closed during part throttle operation.

                    I got my head and intake installed last night. Going to do a once over and fill the coolant and start it up after work today! Thanks for the help!

                      So since the throttle body and sensor are brand new, how do I set them up? I can't get a very steady idle. Some times it hunts around and sometimes it idles ok.

                      I tried to set my TPS at .45v but can only get it down to .6v. I guess I will have to elongate the holes a bit more to spin it. Or is there a "safe" zone that I am within?

                      What about the throttle body butterfly, how do I set that in the right place? The small allen screw and lock nut were loose when I got it. I couldnt find any guides online as I don't really know what I would call it.

                      Other then that, everything is golden.

                        Well I've been fiddling around and googling like a mad man and I can't seem to get my idle. Sometimes it idles ok for a while, and then it start pulsing up for one second and down for one second and so on.

                        It seams to be related to the IACV as far as I can guess. But I dont know if ive got the throttle body butterfly set screw in the right place. I've tried adjusting the TPS for 4.5v WOT and .48v idle but I can Never get below 4.7v WOT. These are the only voltages I've found so thats what I've tried to set.

                        I have tried disconnecting the IACV and then adjusting the idle with the throttle body idle screw and then pulling the fuse, waiting ten seconds, re connecting the IACV and the fuse and starting up. The car will start high idle and come down and move around a bit and then find a stead spot. Then if I open the throttle when I let it down again it goes into the jumping one second up and down state.

                        Parts are:
                        h23 intake manifold (complete)
                        h23 IACV
                        phearable 68mm throttle body (so I have no FITV)
                        f22a1 head
                        Delta 272 regrind

                        Any ideas? Would love some help!
