Just to continue beating this point into the ground, no, there is no 2-stage vtec or dual vtec or anything like that on a GSR. It's a standard single solenoid vtec setup and also has seperate set of intake manifold runners with a set of bypass butterflies. Yes, there is another solenoid for the intake butterflies, but it has as much to do with vtec as your door pop solenoids do.
