Hi there. I've already searched extensively for this but cant find any answers to my questions. I have a 2002 sunfire sedan auto with the 2200 motor w/ on 14,000 miles on the car and motor. Got it form a grandpa lol. anyway I'm looking into turbo charging this car. This is my daily driver, but my questions are this: with a normal turbo setup intercooled and mild head porting with stock internals and valve train what kind of hp numbers and tq can I real world expect to see? and what are you guys getting for gas milage with a turbo on a 2200 motor? any insight and knowledge would be great. my goal is to make a mid to low 14 second daily driver sedan. any and all tips would be great. thanks.

I think you should find more information in the Boost Forum. I would try searching there first.
