Working with such a small displacement limits you on what you can achieve, but it also limits you on streetability as you start playing with parts. You can add more head, a larger cam, etc., but street manners and low end power slowly go down the drain.

I would follow the suggestions of Barn and Love.....either increase the displacement or throw a blower on it. I don't like forced induction myself, so I would vote for a stroker kit.
