Don't bore out the engine, it will screw with your cooling system, something you don't want in a daily driver. Compression all depends on what you want to put into the car. 10.0 to 1, give or take, is about as high as you'd want to go to prevent detonation on pump gas, go much higher and you'll need to use additives to increase the octane level. If you're increasing compression, you'd prolly want to combine that with new cams. Add on top of that your intake, headers, exhaust, and an ecu reprogramming, and you will prolly have some decent performance.
