Turbo project and more.. I have decided to keep the impy and just completly rebuild everything. I will be purchasing the Cartuning turbo kit, a completly rebuilt transmission (possibly a 6 speed if possible), HP Tuners, a cam, rockers, heads, headers, DR's and plan on having a 4 door car in the 10's **on spray and very low 11's w.o spray. Goal is to have between 600-650 whp w/ spray. Project will begin at the end of the year. If anyone has any suggesstions please feel free to comment.

These cars are great, but just not worth the 10k+ plus you are going to put into it. Save your money and get a new Camaro SS or something like that.
If you really want to upgrade the car, then do minor stuff and be done with it.

Yeah, if you are going to go the turbo route, it would be terribly inefficient (cost per horsepower) to do the heads/cam, etc. While you will gain with turbo friendly cam, it is a considerable extra expense and how much power do you think you can get to the ground? Of course if you are making a track only car and are not worried about longevity....stronger axles, slicks, boost, and the occasional replacement of broken hard-parts will get you an exciting ride. For a car that you intend to drive on the street, I would stick with standard compression (some weaker head gaskets, so that if you do detonate/explode something, it is a cheap gasket instead of a piston) and get a serious dyno tune from somebody who has a lot of experience with aluminum block turbo'd cars.
Most will tell you that lowering your compression and raising boost is the way to go to make that kind of power. While I generally disagree and feel that lower boost with careful tuning and standard compression makes for a better package. Crisp throttle response off the boost and the like, however maybe going with lower compression pistons and upping the boost might be just the ticket for a front-driver. Less power down low where we already have too much and into the boost at the top of first and carrying it to second where there would be enough RPM/load to get right back into where it would really shine! Plus, you could always hit the button and get that extra 75 shot if you ever really needed it.

10K+ trade in on the Impala SS would get you damn close to more HP/TQ with a better end result of add ons later down the road
10K+ on a FWD LS4 car is just going to be a lost project after everything is said and done. Dont get me wrong, these are great cars but not great enough to spend that kind of money when there are better options out there.
BTW, how many new Camaro SS cars have you seen on the roads? VERY LITTLE.... So he wouldnt be like all the others since most people do not have them yet.. He would become one of the few to have a great product car with alot of aftermarket support.

Why not have the new SS Camaro & a 600hp GXP
My wife is planning on trading her 2006 Mustang in for an 2011 SS Camaro.
Future plans for my GXP include a LS9 crate motor (supercharged 640hp), 6 speed auto (I'm getting old & this is my DD) & RWD.
Modding cars is rarely a sound investment but the thrill of having something different that you built makes it worth all the sleepless nights, busted knuckles and a little thinner bank account.
I say go for it!

I would love to see the pics of a GXP with an LS9 with a procharger on it, but I just still do not get it..... Then again when I look at my Monte and think about this body style was only made for 2 years and thats it. It really makes me enjoy the car that much more and I want to do more. IE Rockers, better tune and maybe get Headers made.

The new Camaro is just too big, I like it, but I'd never buy it. I like the WTF faces I get when people see my car. 14,000 GXPs, 10,000 MCSSs, probably around 12,000 ISSs, and probably around 10,000 LS, I'll keep my LS4. You can have an LS3/L99 if you want.
I say go for it. Be nice if we could twin charge...

You could twin charge, but you would be driving from the back seats. LOL
I really do think, with the right money you could get a sweet Eaton blower on these cars and mod it enough to be around 400-410hp

Would an LS9 even fit? I'm all for thinking outside of the box and doing something different but seriously? Sounds like you can do alot of work yourself, but for arguments sake, lets look at having some of it professionally done.
Price of the GXP new(assuming you bought it new): around $30k
Price of a RWD and tranny swap with all the major custom fab work that would be needed to done: probably about $20k
Cost of an LS9 crate motor: $25k-$30k
Right there you have a $75k Grand Prix. Different? Surely. Remotely worth that? No.
You could save $20k and buy a CTS-V that would be a greatly superior car in every single aspect. Sure you didn't built it yourself, but you also said it's your DD. Tearing into a DD that much just seems foolish to me. Hell you could even snag a good deal on a G8 GT and get the APS twin turbo for it and still have an infinitely better vehicle for less than $40k.
