K20 = a engine code. no its not 2K CC but its more powerful. in terms of hp and TQ. it runs a faster or equal to 1/4. depending on drive of course.
yes there are DOHC civics. HP is hight but the TQ is so low it doesnt matter.
you need to read alot more. go to
www.cars.com and do a research on the two. hell even motortrend.com can help.
