I have a lot of experience with turbo setup and I like them,,,BUT they are a deep dive, If you want the simplest then the centrifugal are the way to go. you really need an intercooler with anything.

The fuel system will approach 500hp ( iffy) with a 340l pump and 60lb inj. remember the lines are tiny.
