Re:question about manually engaging VTEC
ok dude noone is gonna answer you questions about putting any lights on your car but as far as your $1 manual vtec switch is not a good idea, the fuel/spark maps change at the crossover point and your switch wont do that.
i dont think your friend with the automatic had his sweet light hooked up right b/c i have never seen a dyno of a engine with a crossover that low.

Re:question about manually engaging VTEC
two words: "VTEC Killer"
if you dont care about idle quality or emissions, go ahead and do what you want. Engines still exist without the benefit of VTEC and they run just fine.
Plus 4 cylinders loping sounds ------- awesome
when i first dropped in my y7/z6 mini with comp 59300 cam, i hadnt got my VAFC in the mail yet, so i just hooked up a toggle to my VTEC solenoid. In a cold start siatuation where i had high oil pressure and a high cold idle, i hit the switch a couple of times and it loped and sounded bad *** but i never tried to drive it like that.
bottom line is it wont hurt anything, but it could make you lose power in the low end.
Nobody said honda spent all that money on research and development to make their non-VTEC lobes make maximum power, they are simply to make the car idle properly and maintain low emissions at crusing rpm.

Word to that, But yeah my friend has an 02 civic ex, I don't think they had i-vtec yet, and plus it only says VTEC on his engine head. I don't think I'll ---- anything up if I made a switch though.
