Wow, you guys seemed to have it all figurued out, except one thing. Running higher boost wont make you faster if you have a higher compression ratio to start. These numbers arent accurate so don't complain, but heres an example. If you have a 10.6:1 compression ratio with a turbo on 10lbs you'd be pumping out the equivalent of a 10.1:1 with 12lbs of boost. The advantage to starting with a higher compression ratio means you can run your turbo at lower boost, or have a quicker spooling turbo, in effect making your car faster. Also, C5's, expensive as they are (and yes I agree, they are a waste) can be turbo'd safely, just tune it. But, I would hope anyone spending the amount of money required to install a C5 into a hatch and then turbo it would also spend the extra money with a Hondata (stage 3??) and a knowledgable man on a dyno making it run right.
