GTM has staged head packages from what I remember. If you build the motor for boost, and then run it NA for a while you may be really disappointed with the performance. The CR is going to be too low for a NA car. If you're going for big power you don't want 4.08 gears either. You would want to go the other way. And 30k for the sc kit and install is way off.
