vti or no vti?

SOHC only has one cam, that combines both intake and exhaust?!?!

well the last vti system i saw used a sliding camshaft design with a progressive trapezoid shaped lobe. as you adjust your throttle position, it slides down to utilise the width of the base of the trapezoid to maximise valve duration.
hence it was valve timing with intelligence.

Nope, VTi Coupe was available Pre 99

Post 99 was when VTi-R Coupe aka EM1 was brought in and the only other Coupe at that time was the GLi

oohhh. yeah possibly your vtec DID fall off. you might want to get a mechanic to check it over for you. Might need to have it remounted with the right torque settings to get the most out of your boosting experience....
