short explanation is that VTEC is an oil pressure operated system which changes the timing and cam profile for high upper RPM gains, while still maintaining a normal economy idle-well profile for regular driving, while giving a more aggressive cam profile for "highway-speed lane changing, and onramp entering"

One for intake and one for exhaust as opposed to the SOHC which uses one cam to control both functions.
so the sohc vtec isnt too bad performance wise then? just not up to par with the dohc right? i wouldnt mind settling for the ex model since it comes with the sohc..from what i hear though its worth the wait to find an si

Now if you combine the 10 Hp from i/h/e with some weight reduction , then you can really start to feel things. I would suggest trying to reduce unsprung weight(suspension parts,wheels and tires,etc). Honda's have alot of potential you just need to work at it some times
been there done that
