I'm not going to flame you for being a n00b, however, I will suggest that you start one thread about one topic (ie. B20) - instead of 4 or 5 separate threads about basically the same thing.
Having said that... To mount a B20 (or any "B" series for that matter) you'll need aftermarket mounts. There are a handful of companies that make them, but from everything I've heard & read HASport is the best.
