well, i don't wanna be annoying, but this post should probably be under the "integra" forum....but anywho...to my knowledge i would assume that u should only need the mounts from the B20 and maybe the throttle cable, the B20 will bolt up to the B18b1 tranny, and that's prolly what u wanna use since the B20 tranny is gonna be AWD and will take alot of custom work to make fit....so what u will probably need the usual engine swap parts...not sure tho
