Thank you all for responding. I am not set on turbocharging. I've pondered the idea and may want to try something in the future. For now, I am interested in learning more about it and its peculiarities.

I had no idea about the oil sprayers. So that's featured only in the turbo engines? I had a feeling about the IP differences. And I wondered if the trannies had different shift points. I knew that a total changover is the most predictable and safe option. I just wondered if there was an easier, newer and more effective way of doing it with what I already had.

Some people have done some neat stuff with existing turbo systems. I wondered if anyone has done anything with some of the older systems.
