Sorry for the blurry pic, here's a better one:
Your hypothesis could be true. Indeed there's no VTEC. No solenoid, no SOHC VTEC sound. Of course it can't be carburated. Were there any D15 engines produced in Europe? I heard there was a 1.5-liter SOHC VTEC-E engine for Euro Civics...but going back to the point, I don't have VTEC.
This is weird...but intriguing.
