Then some custom tuning would def have to be in order but I would think it would be awesome in a light crx. The z1 swaps in those already yield 60+mpg.

That's right, flycutting wouldn't be needed with a simple deck/mill. i've ran my D15z1 with upto 6 degrees cam advance without damage.
Some of these are on my list to try (along with the knife edging and coatings). I disregarded the D13 (or D12), since gas velocities would suffer while using the D15z1 top end. Going to an adjustable WAI would be better since it will have a similar effect by decreasing the air density, as well as wall heat transfer. My plan is a air to water IC, along with a ported vacuum heat riser (possibly over winter break).
If you guys like the spoiler setup, look into CCCRacing. I have one of their outlaw rear wings that goes all the way out to the bumper edge, and is a professionally made piece (but a little over the top looking).
