Im looking at purchasing a car with the KB 2.2 without the catch can. Im guessing it's the newer version because it doesnt have the catch can. Can anyone tell me how it compares to the old style 2.2? Does the new one sound anywhere close to the old one? Pros/cons to this style? Also I think this car is running at 19lbs of boost. To me thats a little high for my liking. My plans for the car is a DD with some streetability, I think 17lbs would be safer and less stress on the motor. Any thoughts?
