Advancement amuses me - Initial D edition

In season 2 of initial D, everyone busts a nut over the AE86 star car having a 1.6L racing engine that makes 240hp in race trim but was DETUNED for the street. It amuses me that 1.6L turbo motors are simply "hot economy hatch" motors today. Where they make 200hp normally and 220+ with a simple engine tune. So basically the Fiesta ST has a motor roughly as capable as the racing series specific engine in the AE86 that stars in the show. Technology is a wonderful thing.
