Thread is from Feb. 2005.Not sure about how many lobes in this engine. I had a 07 Honda Civic LX with the 1.8L. It had VTEC but it was reverse VTEC like what you are talking about. The economy version. It is where the engine is already in VTEC and turns off once you hit X-Amount of RPM then you're running the engine normally. I believe the Ridgeline's VTEC "ENGAGES" at 4500RPM therefore it is not the economy version.
Now I-VTEC in the Civic SI, woo now that's a boost in power.
I could be wrong though. IMO
