My old DC5 CR was 11.0:1, i stayed NA but planned on boosting, however car got totaled. But point in case that motor was high strong, many people i know boosted and did fine on stock parts. A friend of mine was pushing 320whp of 9 psi i think with a bolt on greddy kit. Point is though 12.5:1 is pretty high, higher than most wanted it to be, there will be a few kits out there not to mention the few that will custom buld their set up. I prolly boost mine anyway its all about how its tuned, personally im not power hungry so if i can boost and get 250whp running 7psi on stock safely ill be happy.
