Need help turboing slang six

Adding any power adder is far more than just bolting on and adding boost? What is the goal? Sleeper? Turbo is best option for most power per cubic inch. But it's more complex too. Please feel free to express goal? We can get weird too? What are you thinking?
No it’s not gonna be a sleeper, I wanted to add horsepower, gas Milage isn’t so important though it would be nice to maintain good gas lol
