dude, aside for the minimal bigger cubes on the b20, its the same as a b18... the intake on the crv engine has a longer intake manifold design, (more torque?) but you can find ls intakes on cl for like 20 bucks... as long as you build ot right (check clearances, valve lash, timing belt tension etc..) you should be fine... dont try and rev it up to 8k rpms and expect it to last forever... and 650-700 bucks for a jdm b20 is pretty much the norm price these days...anything of of an ls integra engine will bolt right up to that b20..
