when does vtec kick in on a 04 base, auto rsx?

 

the crossover is at 2200rpm. But its not true vtec. I would hardly call it vtec

QFT.

It is not a TRUE VTEC. More like a VTEC-E found in older model Civic's and Accord's. All it does is open a second set of valves on the intake cam, comverting it to flow more air, but it doesnt actually adjust the lift or duration of the valves.
