Forgive my ignorance, but is Nissan's Continuously Variable Timing Control (CVTCS) equivalent to Honda's VTEC? Do both version essentially serve the same function? Thanks in advance for your help! Apologies if topic has been covered.

Since they didn't say anything about two-stage lift, my guess is no, it is not equivalent to VTEC. Someone familiar with the VQ engine can jump in and fill us in on the details.

No they aren't the same thing. Nissans CVTCS only deals with cam phasing. Up until the 05 G35 6spd and 350z Track/Anniv edition, the cam phasing was only applied to the intake side. With the new G35 and 350z, it is applied to both intake and exhaust side. You can say that it is very similar to Toyotas VVTi and BMW's VANOS. The only technology that Nissan has that is like VTEC is Neo-VVL. This uses a 3 stage setup when changing the valve timing and lift. Cars that used this technology was the JDM Nissan Sentra, Nissan X-Rail, and Nissan Pulsar(there may be others, but that's all I remember off the top of my head). The Nissan Pulsar that uses the SR16VE-N1 engine has 1.6L with 200HP. The X-Rail uses the SR20VET(280HP) which is the only production engine in the world that uses Variable Valve Timing and Lift along with a Turbocharger, only Nissan saw fit to put that engine in an SUV .

CVTCS was used in the Civic back in the 80's. CVCC remember!!! It's a cool technology but it does not compare to VTEC. Nissian is using CVTCS because they want to get better gas mileage for their SUV's.
