If you ask me, I think you should opt for a supercharger. Jackson Racing dynoed a 5th gen with just the supercharger at around 240 whp, so that's right up there near your desired power level. Not only that, it'll be a helluva lot easier job to install (might even be able to do it yourself), and this may be slightly subjective, but the JRSC would be a more reliable option compared to a turbo, there's just less that could go wrong. You won't have to worry about turbo lag with a JRSC, and their belt is supposed to last like 100k miles or something. Lastly, I believe you can get a JRSC for a lot cheaper than any turbo system. Of course one of the downsides is that yes, there's more tuning options with a Turbo, but didn't you say you're not into the technical stuff as much? The JRSC would be perfect for you if that's the case.
