Ok so the guy was not around when i left today to get underhood pictures.
Aside from the intercooler, CF Lip and Hood, maybe the wing, people wouldn't really expect 670hp out of this thing. I have seen intercoolers on cars that didn't have turbos, and most turbo'd integras around here run around 300 hp.
I guess the guy used to tune to make money, and apparently does a really good job.
