Honda motors are not known for being great for high boost since a lot of them are very oversquare (my HX has a 75mm bore and 90mm stroke) and open deck blocks with thin cylinder walls. That's all great for high efficiency and keeping the block very light and able to cast off excess heat, but not good for getting beat on by the abuses that go along with a high boost turbo setup.

That said, I still feel that Honda motors are plenty strong for a light pressure, 6-7psi setup given sufficient fueling and perhaps some way to pull back the ignition timing a little bit under boost. Good luck with it, if you do decide to turbocharge your Civic. Definitely take pictures if you do, I also have never seen pics of that guy's turbo Insight, altough I imagine it probably looks a lot like every other turbocharged Honda I've seen, just smaller.
