VTEC CLIFFS NOTES:
SOHC = intake side affected only
DOHC = both sides affected
GSR = 2 stage VTEC (on or off) and butterfly valves in the intake manifold
obd2 d15b vtec = 3 stage vtec (12 valve -> 16 valve -> "performance" 16 valve)
SOHC = intake side affected only
DOHC = both sides affected
GSR = 2 stage VTEC (on or off) and butterfly valves in the intake manifold
obd2 d15b vtec = 3 stage vtec (12 valve -> 16 valve -> "performance" 16 valve)

ok there is a dual stage vtec, no it's not gsr, it's OBD2 D15B, look it up, it has two vtec silonoids. From around 3000rpm up to about 6000rpm, the first VTEC actuator switch engages and the previously inactive intake valve now goes into operation. The engine now runs in 16-valve mode behaves just like any of Honda's highly spec'ed 16valve PGM-Fi engines. After 6000rpm the second VTEC actuator switch engages the wild cam/rocker arm pair for the intake valves. This switches the engine into the wild-cam mode where it goes bonkers delivering 130ps at 7000rpm. With the proper driving style, one can actually enjoy mileage as high as 16 or 18km/l in town driving while at the same time frequently indulging in VTEC-inspired sprints to overtake slower vehicles.

Add a turbo and see exactly what a pointless waste of engineering VTEC really is. Better yet, how many other things you could have done with your time than argue about it. :cat:
I love it when people talk about VTEC like it makes the difference between making ice and boiling water. Don't talk about fuel economy because nobody in here arguing about it is keeping their foot off that gas pedal when they drive.
"Okay man, lets go again. My VTEC didn't kick in."
