lol. Alan got in before me. Basically, it's easier to extract large amounts of power out of a larger capacity engine than it is out of a smaller capacity engine.
I'm tempted, love the idea of a bit of an NA build, but also love a turbo build . My turbo setup is a bit old and needs a bit of work to get it back up to scratch, the turbo needs a rebuild or new turbo (hard to turn turbine, even by hand) and rebuilt carbi. See my intro post if you want to check out how the previous owner hooked the turbo up. Has to go back to NA for RWC anyway but then we shall see what I do, but that is a fair way off at the moment Actually, I should get off my butt and make a project thread..
