Its not right: first you say at 5000 + RPM than you say at 2200 RPM..there cant be two vtec engagements you know !3. The K20A3 engages VTEC at 5000+ RPM.
Wrong. Technically, there is no "VTEC" (as we think of it) in the K20A3 engine - it uses a VTEC-E technology, which engages at 2200RPM. Read under "The Second Sytem" above.
