Thanks, Scoot. I do appreciate your post. It seems to be made in my best interest.
However, I indeed want a smaller dispalcement. I don't just want to be different. Though my goals are different, my intent is not just to be different. I know it is not a popular mindset in the turbo community, but my goal is fuel efficiency. With the ca18det I think I can better the fuel efficiency of my ca20e, though it is not shabby itself. However, with a properly tuned small displacement turbo, water injection, and a few other modifications I think I can get well past the ca20e's potential, and even have a little more pep to the engine if needed even with the smaller displacement.
