Hmm I could remember sir volts say something about his ES Civic which has a d17 engine. If it is indeed that vtec3 variant which could well mean a 3-stage vtec implementation, then I guess you must be right on this sir type100.

It could be our local d17 engine on the ES has a 3-stage implementation.
Is this the VTI-s with the VTEC3 sticker in the rear windshield?
