I have a 2001 UK Civic 1.6 (7th generation 5-door hatch). The engine code is D16V1, but I have not been able to track down any detailed technical information about it. It is claimed to be a SOHC VTEC-II design, power and torque being relatively modest at around 110bhp and 105lb/ft (from memory). Max power is below 6000rpm, and max torque is just over 4000rpm. Economy seems to be the primary objective (we have two sporty 2.0litre models available with 160/200bhp). I am getting 39-43mpg (our big gallons) fairly consistently in mixed driving, and the engine is not unduly straining below 2000rpm. If this is a derivative of the VTEC-E, then the transition is very well masked compared to a 1.5 that I drove some years ago (you didn't really need the light on the dash to tell you both inlet valves had opened as there was a noticeable "push"). I cannot honestly detect any real change to the engine's character as it revs, particularly with the a/c off. With it on, I think I can feel something around 1800rpm and again at 3600rpm, but I wonder if this is not the a/c clutch doing something. (My car also has climate control, and the a/c kicks in and out quite frequently.) I have been all over Google, visited the temple of vtec, etc, but information on this engine derivative is practically non-existent. I'd be grateful for any pointers, if only to satisfy a nagging curiosity as to what's going on under the cam cover !
