    H22 performance question

    I heard that tthe difference in h22s between automatic and stick is more aggresive cams and a larger throttle body with the manual version. is this true?

    Only the cams are different. The tune may be, but the biggest difference is the cams.

        Where did you get this info from?? Because you are completely wrong.

        The cams are exactly the same on the auto and manual.

        primary int: 34.041 mm
        mid int: 36.856 mm
        secondary int: 34.971 mm

          I would say prob ECU tuning and the loss by the auto trans if not that.

            there is a difference in the f20b, but the bullshit write up by sport compact car that said there was a difference between auto and manual h22as was just that, bullshit

            there are NO differences in any version of the h22a between auto and manual other than timing, but even the ecu tune is the same.....

              Did you actually measure both sets of JDM OBD-I cams, or is that a spec from a book somewhere?

              My info did come from the SCC issue, and there were a couple of other discrepancies in that article as well, so it wouldn't surprise me if they were wrong about that too.

              Unfortunately, I haven't run accross a lot of "autocam" JDM H22s, so I haven't had a chance to measure them personally. Perhaps I will find the time.

                Yeah ignore it, lets face it SCC doesn't really know what they are talking about when it comes to any engine that should be in an Accord

                  the JDM cams are different, but this was not specified on the original post.

                  this is coming from honda's service manual

                      I figured that might be the case. I assumed JDM, because typically if they refer to auto H22 and CB7, they are usually referring to JDM (especially since he implied a power difference) as it was the only OBD-I auto H22, and they seem to be relatively common in the marketplace. They are also usually cheaper.

                      I also assumed that JDM OBD-I auto cam specs were different because of the rated power difference. Obviously this is not the case on USDM OBD-II H22s, because they all have the same power rating.

                      Like I said, I will find a set of JDM "auto" cams and figure out if they are the same.

                      Yeah ignore it, lets face it SCC doesn't really know what they are talking about when it comes to any engine that should be in an Accord
                      SCC usually just prints what their source for the article tells them. CD swaps were still fairly new then, and the source for the article was actually HASport.
