camshaft and compression ratio
lots of turbo cars are carb fueled, some blow through, some pull through.
I'm just saying for a first project,, a turbo slant woud not be an EZ start.
Not saying it could not be done, go for it if you want it,, or say you want it, but are willing to build a foundation, so that when you get it, its done right,, and that's what I'm talking about
