It is confusing, especially considering the 1.5 is the only one without VTEC, but it's still called a VTEC Turbo because that's the marketing term for this whole engine collection.
The slides in the photos in the article are from Honda themselves on introduction of the engines for the European Civic, and they show that the 1.0 has "DOHC Dual VTC + Intake VTEC", whereas the 1.5 has "DOHC Dual VTC" only. In the thread Design linked to, there's a slide from the technical presentation of the engines for the North American Civic that cites "DOHC Intake/Exhaust VTC" with no mention of VTEC at all. Here's a video with Honda's Chief Powertrain Engineer Yuji Matsumochi where he goes over all the technical aspects of the engine, and at around 2:00 (I tried to link right to it) he mentions the VTC.
Thanks a ton for this!!!!!!
That looks almost identical to the VTC on the Nissan 2.5's that I've worked on...wonder if it's any better
