Turbo six on a Budget

I am far far from a turbo expert, know damn little about their fundamentals but I'm looking for easy.
I get what the difference between blow thru and draw thru is but which is better?
And for what? I'm talking is one better for a truck that works like one, vs a turbo in a hi perf car?
And following the K I S S rule I'd like to stay carbureted.
