it has a very similar torque and horsepower rating, but since the torque develops sooner it is more desireable.
in terms of adaptability, the restricting factor for the b20 is the head design, which just isnt enough for a 2 liter engine. i'd imagine you'd gain quite alot out of just a basic port job.
