if quickness is your goal, thats a perfect fit. a B16 in a crx is one of the cheapest+fastest combo you can get since the swap is cheaper than a gsr, and the crx weighs less than 2000 pounds
for fe, stay away from it.. just like what dave1215 said, it will be about 25 mpg on premium
I knew someone from my highschool days who had a part time job and a civic vx, lives 25 mines from school. after saving enough money from extra hours from summer, he bought a B16 swap. right after that he never really hung out or did something fun because his 50 mpg vx became a 25 mpg vx on premium, so its more than double for gas, and he never floors the thing because of gas prices (premuim). so its a worthless swap
also hes 10x as paranoid since he has a DOHC VTEC under the hood
