yes, well actually it's called a 3stage vtec. it only comes on the jdm d15b motors. it's kinda odd to look at if you know your honda motors well, because it has 2 vtec solenoids whereas every other motor will only have 1. this motor is made for economy and has the capability to produce some impressive mpg values.
but on the other note. your gsr, lol. you have VTEC. 1 stage. thats it.
1000-4499rpms= no VTEC, Closed intake manifold Butterflys
4500-6199rpms= no VTEC, Open Intake Manifold Butterflys
6200-XXXXrpms = VTEC, Open Intake Manifold Butterflys.
And As for assessing your cars problems, good luck. if your stating that your car hesitates when you are full throttle, then it could be your fuel pump. but if it were so you'd be hesitating reguardless of throttle position.
try explaining things a little better. cause your post might as well say, ''My cars Not Starting. What could it BE?"
