I agree.

Not only is VTEC spelt wrong but it overlooks the fact that VTEC/VVTL-i allow you to run a lumpy cam on the street without sacrificing a smooth idle and low RPM pulling power.

As for Nissan, the SR20VE is the only engine (AFAIK) which has variable valve lift and was found in the primeras in Japan. The SR20DETs found in the 180sx etc only have variable timing and I belive thats only on the intake (or was it exhaust) cam.

As for the title, you cannot compare VVT-i with VTEC. The proper comparison is VVTL-i with i-VTEC, where both allow continously variable valve timing.

I posted a link up in regards to the SR20VE someone around here so search for it if you wanna learn more!

Ok now lets discuss VVTL-i vs VTEC/i-VTEC!
