Just to answer about the turbo install, it's really not hard, everything is bolt on, no welding or anything like that and the install manual is VERY detailed with pics and directions. Someone who can put on a K&N intake can put on the turbo kit as long as they follow directions and take their time

The detailed manual is available on the Cartuning website (Cartuning.ca) or more specifically
http://cartuning.ca/products/wbody/c...stallation.pdf
They quote 10 hours but recommended allowing 2 days..
It took me and a buddy about 24 hours to put the cartuning turbo on, but I bought the kit used and I didn’t organize every thing first and had to fab a bracket for the front bumper. If I would have organized every thing first and followed the instruction (just got a cold chill) probably could have got it done in 16 to 20.

Technically the GXP is a track-tuned performance sedan... Pick one up for 12-16K, drop that 10k into it and you have a 11-12 second sleeper that seats 5 people.
I know of a lot of FWD that would destroy most RWDs, before you say, "Yeah, well they can't corner fast." The track is a straight line.

Why not just dump 10k into a 98 LS1 Z28??? Have a mean 9 sec or 10 sec daily runner?

Because everyone else in the world has done this.
I like rare cars, and mods.
I see a few z28s a day heading to work (shop).
Kids going to school mostly.
So there is nothing too unique about them.
I have maybe seen 2 GXP's on the road since I picked up mine.
Also when you work with corvettes
you want to have a big 4 door car with a real trunk.
atleast some of the time lol
For me if I was going to build a camaro,
I would just put that much more money into
the vette.

Then why give the GXP Bilsteins (for better cornering), cross-drilled larger rotors (keep cool and stop quicker), staggered wheels (cut torque steer and help cornering), manual mode (drawing out gears without a tune), etc. The GXP is different from the other LS4 W-bodies in those ways. The SSes and the Super are more DD material, the GXP is a good mix of track car and DD.

Many MANY cars on the road today come with Bilstien shocks, this doesn't necessarily make the car a track car because those Bilstiens arn't valved anything close to what they use in racing applications, or even for a base BMW for that matter...
Cross drilled rotors don't help you brake, and don't help keep the rotors any more cool, if they do anything at all they save some very minor rotating weight (at the cost of making the rotor weaker and having less swept area).
Staggered wheels are GM's cheap engineering to combat the 300+ft.lbs the cars make at the front tires, its simply cheap (but effective) engineering.
And manual mode? Are you kidding? Almost ALL cars on the road today have some sort of manual-shifting mode automatic.
The GXP is a quick sleeper sports sedan, but not a sports sedan in the same sense as a BMW M3 or CTS-V etc.

I’ve been reading through this thread with some interest, as I too would not go to the “uber” lengths others have to modify what is, in my view (and that is the operative here), a substandard platform. This is the second W-body I’ve owned (the other was a ’99 blown Regal GS I modded quite a bit), and both were under damped and under sprung. With the kinds of resources being bandied about here, I would sink that money into an ’86 or ’87 Turbo Regal that would go like stink after I got done with it, seat 5 (six with a front bench), get over 20 MPG and come out $10K ahead. Does the car in my avatar look like one that would run 12s on those whitewalls?
Also, in my view there is a limit to how much horsepower one can safely use on the street. Driving a 10-second car on the street is a hoot if the drivability is there, but you can’t unleash that kind of power in a non-controlled / police-patrolled / clueless driver-occupied environment, and it becomes no fun after awhile. I have seen drivers get in way over their heads because they got greedy, and unfortunately it takes an expensive lesson for them to learn their limits.

no ****....you cant compare the GXP to those cars considering that a brand new GXP was $28,000 and a new BMW M3 or CTS-V which are $50,000+
