RE: toggle switch for vtec.....
its a d16, you can HARDLY feel vtec anyway, you notice it a little more if its cammed but good luck "Feeling" the car accelerate harder when it engages, you aint gonna notice it enough to fine tune it by hittin a button.
i honestly cant feel vtec in my 99 d16y8, it pisses me off, people ask me if my car has vtec, im like "hell yea" and then im just embarrased cuz no one can ever hear / feel it... thats why you get a cam and a turbo, you can hear the S.O.B then lol
if only sohc vtec would open up the exhaust valves also, i dont know why they only open up the intake side... someone told me they couldnt do this cuz spark plugs were in the way somehow but i dk...
anybody know why the sohc only open up intake valves and not exhaust? im just curious

because then you'd lose fuel economy all through the lower rpms because the camshaft is opening the valves more thus letting in more air, thus making it put out more fuel. It'll obviously give you more power, but i'd say overall it will just make you lose fuel economy way more than it'll make you gain power. Also, i wonder about wear on the components from having vtec enabled all the time, because even if you redline all the time every time, those components are only getting used like 1/3 of the time... so they wouldn't have to be made as durable (from honda's perspective) so why would they spend money on strengthening things that dont need to be. Idk, thats all the input i have on it. anyone feel free to chime in.
ha, so i just clicked on the post link from the homepage and only saw the second page of this thread... so not much of what i said has much standing i guess in terms of relevancy

exactly...its not a DOHC. it would be utterly impossible to make an SOHC cam that can open up both sides, it just literally isnt possible. the cam would literally have to spin both ways at the same time (hens the impossible part). Oh, and about the button, seems pointless to me when you can just go out an buy a nice little unit, say from apexi of skunk2 that will adjust your VTEC engagment to where you want it so you dont have to push a stupid button every single time. you should put N2o in your car so you can have two buttons....that would be tight.

yeah with the VTEC it isn't engaged all the time, it gets engaged at 5400 rpm (or whatever), but i really dont think the MPG difference is noticable, dont really see why you wouldnt want it ever
