Turbo project and more..
The turbo kit for these cars is good for 500+ whp.
After all, it is the internet. People aren't always going to see eye to eye on ideas.
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.
I only paid $16,200 for my 2008 GXP with 9,200 miles on it so I've got a head start there. I don't have a car payment but I do put money in my "Supercharger Fund" that my wife started for me a few years ago.
I like the looks of my GXP better than the CTS-V. I don't like the G8 as much either but I like RWD better than FWD.
I don't plan on tearing into the GXP until she's at least out of warranty.
What I'll probably do is buy a supercharged LS powered Camaro or Corvette as a donor if I go forward with the conversion.
Modding cars can turn them into money pits quickly. I have 7 modded cars at my house right now. The only stock car I have is my 1st car which is a 65 Mustang Conv but it's in storage for now.

As far as cost goes, I still think it's a good investment. I've debated trading my SS in for a G8 GXP or (god forbid) a Taurus SHO. But both are $40,000 cars. I paid $25,000 for my SS and, with $10,000 in modifications, I'm still over $5000 cheaper than the G8 GXP, Taurus SHO, or a Charger SRT8.
Plus, like others said, it's nice to have something no one else does. I can't wait to smoke a few Mustangs, Camaros, and even a base Corvette. Imagine the look on their face.
Also, your 40k price tag would come down a bit as these cars are just not selling. So you might beable to get a steal when buying one.
Again, its better to get a car you know you can mod with the correct parts out there vs. something that was thrown together. What I mean by this is having the bigger names out there like SLP, ProCharger, Magnacharger, Kooks, Year One, etc making parts for the car vs. trying to make parts for an LSX fit the LS4.
Just wish we had more options.
