I think only one of the Toyota's iv-whatever-i offers a different valve timing for a higher rev like the vtec (in the Celica GTS I think). Others are just labels for Toyota owners talk crap back to the "vtec" crowd.
VTEC and other valve control systems offer a wide range of options when making an engine.
this engine uses something that is most likely more like the EP3's iVTEC, which is tuned for better fuel economy vs more horsepower.
the only reason there is a supercharger is without it theres no sport 2 door for toyota. (that i can think of?)
