U can check u own.
I m not saying that 1.8 VVTi is slow.
1.8 VVTi generates 134 hp and 1.6 VTEC generates 129 hp.
Tecnically it seems to be that 1.8 VVTi is faster but on the track (do it ur self) 1.6 VTEC smokes 1.8 VVTi as HONDA's VTEC performs best on HIGH RPM.
If u r interested i can give u the reference.
