Difference b/w VVTI engines & ones in local cars

What is the difference between VVTI engines and the ones that are used in local assembled cars. Is it supposed to be a good powerful engine?

Any feedback would be appreciated.

Hello!
well INDUS Toyota's Corolla Xli and GLi 1.3L came up without VVT-i whereas 1.8L ALtis came up with VVT-i....!
well VVT-i is a valve lifting technology like HONDA's i-VTEC
its used to adjust camshafts a/c to situation.......!
In VVT-i.......i stands for intelligent...........in which Engine oil pressure is applied to an actuator to adjust the camshaft position.....
well in 1.3L VVT-i and 1.3L simple 2NZ-FE engine...there'z a difference of almost 6-7HP.........VVT-i provides better torque range than simple on on low RPMs..
VVT-i powered 2NZ-FE puts torque around 123NM@4400 whereas simple one around 119NM@4400RPM
Thanxxx
