Stay NA or go to the Dark Side?

Alright guys, so I'm at a fork in the road with my Z. I'm in Afghanistan again, this time as a contractor. With that being said, I now have some cash to put into my Z. As you can see from my sig, I have a lot of parts on it already. The problem is, it is not making the power that I thought it would or should. It's currently at 306 whp and 236lb ft of tq. With the Motordyne manifold, it was 304 whp and 243 lb ft of tq. At it's highest (end of march), it was at 316 whp and 248 lb ft of tq. I replaced the precat passenger side 02 sensor because it had some funny readings, or not reading at all. Still, with the mods t has, on a dynojet, I was guesstimating in the 320-330 range in hp after tuning. I know there is something else going on with it that I haven't found yet, I just don't know where to look anymore.

Here are some mods that will be going on the car regardless of what I choose to do. I want it to perform regardless if I take it on a track day or cruise around the streets of Las Vegas.
New flywheel and clutch | new rear diff | new sway bars and coil over setup | brake lines, fluid, and pads.
I do want to replace the front bumper with a Stillen unit or something similar, to improve airflow into my intakes and brakes (Stillens brake cooling kit). I am also looking at a hood replacement to help vent some of the crazy heat coming out of the engine compartment.



Now the big question that I have is should I stay NA, or go some type of forced induction? If I'm sticking NA, I seiously need to find a way to push at least. 350whp. It's not because I want a bigger Z penis, it's because I want it to stay in line with the current and future crop of performance cars coming to market that the Z competes with.

If I were to continue going NA, I'll most likely be looking at the JUN cams. Anything else would cost an astronomical amount of money.If I were to go with a supercharger, I've been taking a serious look at GTM's twincharger setup they've been building. The three big questions with that setup is will my big a$$ oil cooler fit with their intercoolers, and will my headers fit with their system. Lastly, is I have NST pulley's installed, I'm not sure how it would hold up with a SC's running on it. And lastly, if I were to look at a turbo setup, I prefer twins. With dual intakes and a V6, symmetrically it makes sense. Again, big question is will my 72 row oil cooler fit. Problem is, I will have to remove the headers. With the turbo and supercharger option, I'm not chasing numbers. I know they will perform. With the exhaust still being a Y pipe, and having 18" resonators, I'm thinking that would have to be replaced with something else as well.

So what I need from you all and your combined brainpower, expertise, experience, and opinions, is what option should I go with. Anyone can chime in, excluding Trolls and flammers. The build won't happen for a while, but parts would start ordering while I'm out here. At the earliest, the build will start is i January, at the latest, probably in April or May next year. And thanks all in advance for your help with this.
