dont knoe much.. but these engines are mroe fuel efficient & they are able to squeeze out as much power as possible from the little engines.. thing is to get power and torque out of these engines u gotta rev the engine real high.. like 6-8k rpm when the cam profile start to change.. which would be crap compared to other makes like turbo nissans where max power starts commin in only at 3krpm-ish and have torque down in the low rpm range .. they're super fuel efficient and really fun to drive tho haha..
