Yaar at first you guys scream about the reborn having 140 HP and Liana having 90 HP. when the tables are turned on U guys U guys start talking about Power/weight ratio. 
Meray bhai, a car is a package ( which include an engine and a body of certain weight) which is sold to a customer. Everyone knows that Baleno GTTi 1.6 Ltr engine out-accelerated competitors. Reason = faster package. Honda and Toyota sold a slower package.
Lets see a comparison here:
Baleno 99:weight 890 Kg, 97 HP, 104 NM torque
Civic 99:weight 1069 Kg, 106 HP, 140 NM torque
Baleno faster acceleration than the civic.
Yes, the engine was legendary and I do know more about it because when you were in class 4 or 5, I was driving one and hanging around with the people whose opinions are now considered expert. According to people of that time, it was a legendary engine 
Heck, lets talk about the G-series Suzuki engines. The G13bb was legendary and it was made so by the swift GT. Now if you do some research, you will find out that the swift GT was a legend of it's time as well
It remained in production without any major changes in the world for 11 years. That is not a small feat.
