a friend of mine found a f20b online and wants me to put it in his 02 accord it has the f22 i think it has the 4 cylinder vtech motor that the car came with and he wants to know what else he might need if anything

 

f20c5? f20 what?

any four banger will do a minium for such a heavy car, h22, f20 you name it.

if you really want something noticeable, get a CL-S 6speed
