** how much increase in power to expect? try my ratio and proportion....its magical.... hahaha
2. Reduced piston but no increase of power = reduced fuel consumption (current eco cars)
3. Reduced piston and reduced power = more reduced fuel consumption to comply with more strict emission regulation
Kung alam mo na sana....
More cheers!
