In reply to pres589:
Interesting that the observations are that it runs a lean cruise mode. Technically, that's a defeat device. Well, unless it runs lean cruise on the required emissions tests (and with front and rear O2 sensors, it's not a trivial standard that it's required to meet). The older carb models were probably tuned for lean cruise, and were fully compliant, and ok. But with that kind of set up, eh- I suspect that while it may be tuned for lean cruise, it may not be exactly legal, that being for Honda, I mean.
With that kind of VTEC set up, and I WOULD call it VTEC- off is just a different version of on, that basically turns up the swirl a lot, in theory making it more lean tolerant. In theory.
All in all, it seems as if you are on a good path for a solution. The one think I would tell you- with a NB O2 sensor, you can't really run closed loop lean. So IF it's running lean intentionaly via Honda, putting in the WB set up, and moving the stoich point richer may not really do anything since it's likely to ignore the NB sensor anyway.
So, now we have tangented off of the OP in a long way. Well, except that it's the obvious solution to a 13 sec quarter mile and 30mpg out of the box....
