What they call VTEC in that car is switching over from 12 to 16 valves.
In the K20A2 (02-04 S) K20Z1 (05-06 S) and K20Z3 (06 Civic Si) engines, they run in 16v mode all the time and when a certain RPM threshhold is exceeded (in my case, I have the Z1 so I crossover at 5800RPM) my engine switches cam lobes to a much more agressive setting. That's how I make power all the way to ~7600RPM
you said the ECU is disabling the other 3 valves right, lets say i got an ECU that enables the other 3 valves, would that give me 'real' VTEC?
btw i have an 03 EP3, does that change anything?
is mine running all 16 valves?
i dunno, just wondering.
