VVT just means variable valve timing, VTEC means something like Variable valve Timing and Electronic Control or something like that I don't remember exacly. They just change the timing of the valves. Mazda's VVT changes the phase between the camshaft and crankshaft rotation, and VTEC switches between two different cam profiles.

Cant really compare Honda's and Acura's VTEC to Mazda's VVT. VTEC has another cam lobe and VVT doesnt. VTEC has "lift": the engagement of another higher profile cam lobe at a certain RPM. DOHC VTEC has it on the it on both exhaust and intake cams, SOHC only benefits the intake half. Then there VTEC-E, i-VTEC, and a 3 stage VTEC. The surge of power ( MORE noticiable in the DOHC versions) is the "lift" engagement i.e Civic SI, Integra GSR and Type R, RSX Type S, Prelude base model and SH, etc. Toyota's VVT-i is comparable to Mazda's VVT.

The only other cars (that I remeber) that can compare to the VTEC in Honda's SI's and other VTEC with "lift" line up, is Toyota's VVTL-i in the Celica GTS and Lotus Elise. VVTL-i = Variable Valve Timing & Lift - intelegent. The GTS uses another cam lobe that engages at 6000 RPM ('00) and 6300 RPM ('01+). VVTL-i is a bit more advanced than Honda's VTEC.

I had a 2000 GTS and miss it. There's nothing like hitting lift. It feels like nitrous just kicked in.

It's beem explained before but just wanted to help out. Variable timing is a lot different that variable valve timing with "lift".

That was a good year for the SI, My lil brother had it in SI blue back in high school, fun car![/b]

I remeber that color. It was very popular. Electric Blue Mica. Theres no other color like it. The Integra GSR and Prelude SH had a similar color but not quite the same.
