Just turbo yours.
N/A builds are too expensive for the small amounts of power you make and the LS4 isn't worth the work or money you'd put into it.
Top Swap's are a grand or so depending on how much money you put into it. Turbo builds can touch 10 grand with extensive work but make LOTS of power.
If you aren't willing to take people's advice then don't ask. QuikGT knows more than most people on here about these cars. Then you say he was bashing you. Seemed like a great answer to your question. If you can't handle contructive criticism I don't know what to tell you.
