that's wrong - do /not/ "bypass" the pressure switch. you have two sets
of cam lobes - one for high revs, one for low. if you don't switch the
cams, you'll be stuck on one or the other, with sucky performance at one
end of the range, depending on how you're switched.

ideally, you need the vtec ecu - it has a higher red line than the
non-vtec as well as the right switchover programming. but if you don't
use one, you can also use a rev sensitive switch to handle the cam for
you. google this group as the same question came up a few weeks ago.
