looks like u people are confused..swapping a b16 into 2002 civic would mean lotta hard work and fabricating and building custom things,whereas a k20 is almost bolt on,no problem to worry about....bcoz even if u swap a b16 and then plan to sell it,it wont get u much,as from a k20 u can have hopes as it would be neatly done,if ur getting a complete deal,then its worth it,like i almost got the complete half cut of it,swapped everything engine,guardry,shocks,springs,joints,brakes etc etc
If u dont get hands into this deal,then sell this car and get a 99 civic,more options and less chick chick.
Best of luck
