Boosting a 2007 Civic EX?
The high compression ratio will cause you problems. If the anti-knock sensor will ****** the timing sufficiently while boosting, you may get by with 12 lbs. Another method is to install water injection. This will flash to steam under boost, control detonation, and give an additional 15% on HP. The problem is it must be reliable. The first time it fails to inject under boost, you could melt a piston. Better yet, trade the Honda for an older Supra turbo and dial the boost up to 18 lbs. O-ring the head gasket, install a racing clutch and hang on. That was the fastest car I ever owned.
