The B20Z in a Civic represents a monster combination, and yes, there are some that have done it. I know a guy that is in the process of doing this conversion (into a '97 CIvic DX). It doesn't make all that much hp (less than an Si), but the beauty of this is that this engine has a long stroke and is geared for torque. I haven't seen any performance stats, but you can bet that Civics with this engine will be quick.
