A trubo causes at least twice as much stress on the engine in comparission to a simple compression increase. 13.1 can easily be done if the car is run rich from idle to about 4000 rpms on pump gas. Race gas (100 octane) would be ideal.
Gaines could easily be 20 - 25 whp. Losses could be a blown engine if you run in to some serious detonation due to lack of proper engine management. You can't just drop pistons into a car. It's not like an intake.

I would think that you couldn't get much higher then 11 or 11.5-1 and stay with pump gas. Here in Florida you can get 93 octane but in Colorado (home) you can only get 91 octane. That makes a difference too.

i would go for 10.0.1 or 10.5.1 . the most 11.01 but its going to be hard to tune to 91oct and pass smog! 12 and higher is racing pistons you are going to need 100 or higher octane and it's going to suck to start up your motor!
