Depends on how much money and time you want to spend under the hood!... if you got the money(especially to go 14psi, and keep it daily driven), go b18c/turbo! If not you can buy a b18c, hook up the engine(cams, pistons, ect) and go n/a. n/a is less maintenance compared to a turbo! I'd love to go turbo but theres not that much money or time!
