If they are different in SPEC I don't think it affects performance at all. Both of my JDM H22s are from autos and still seemed to make more power than the average USDM manual H22. From what I can tell, the USDM Base/Auto/SH all use the same cams.
Something I am alomost positive about is the AUTO Throttle Body being 2mm smaller than a manual.

its in my service manual. I'll check once I get done doing a few things.</TD></TR></TABLE>
I thought I remember hearing that but the parts numbers for the 3 are identical. I don't see why they'd do that. Honda is pretty good about universal parts compared to other cars.
