Sirs
Why are you expecting to feel the power curve of a D series VTEC which is supposed to be the heart of a family sedan.
Have you ever felt the kick of N VCT in Nissan Sunny or MIVEC in Lancer or even vvti or vvti tl in GLi and Altis.
That should only be expected in a b series or K series engines.
If the VTEC will not work, car will have a serious power deficit, floor your pedal down and you will feel a slight change in power at around 3,000-5,000 RPM.
VTEC will only add to power and acceleration will not be effected.
Regards
