Mmmk here's my 2 pennies. My Ctr is 10.5:1 comp and is set to run up to 12 psi. The Ctr is built a bit better out of the factory that being said, I wouldn't run much higher than 12. Talk to a tuner they usually know their stuff since they do it for a living. In my mind a turbo is a bolt on since you don't have to even take off the valve cover. But seriously stop playing around on here and talk to a tuner.
