If so, pros, it will support more power than most Vettes will harness....cons, time, money, a little fabbing to make it all fit, oh, and time, and money....lol.
You'll want to look into a way to get rid of some heat under the hood as well, and get used to being sideways under throttle.

you can get these kits to work and work very well even with VERY hard driving! AVB on here has a PTK kit on his 408 vette that he used for road course work. thats 20min HARD driving per session...
also nick yoskin on here has made over 1000bhp with the same kit.
yes you cant just bolt the kit on and drive around at full throttle all day and not expect heat probelms. but with a little bit of thought you can get rid of them.

Thats my car.
It is the ebay kit.
100% stainless except for the cold piping which is aluminum. The only alignment problems I had was bolting one of the manifolds to the head; I had to open up some of the mounting holes very slightly.
If I had to do it again, I wouldn't. I would of made my own kit since I've chopped this one up so much already.
Otherwise, for what I paid, it produced decent numbers.
Here's a dyno on the stock LS6 @ 7psi.
Here's a dyno with my current 440ci LS7/L92
Those were with the... and I quote... "crappy"... Ebay/chinese T61 turbos.
Since then, I have upgraded to Turbonetics TC76s only because I wanted more. I was getting too much backpressure on the turbine side on the 61s to make the power I want. I've also upgraded downpipes (completely 3"), wastegate piping and wastegates (50mm). Hopefully I'll have numbers within a month.

I didn't chop it up due to any alignment problems. Those pictures were before I did any piping modifications. The only fitment issues I had was one exhaust manifold mating to the head. Some bolt holes needed to be opened up slightly.
I chopped it up because I wanted a completely 3" exhaust; the kit has a 3" v-band right at the turbo but immediately necks down to 2.75". I cut that out and re-did it in 3". Also, I cut the downpipes in multiple pieces and installed v-bands to make it easier to install/uninstall.
Also, I re-did the piping to the wastegates. As someone said earlier, the angles were wack and I was having some boost creep. So I did them in 2" with a lot smoother bends while giving the new 50mm wastegates more exhaust bias.
Next I'll be re-doing some of the charge piping. They are 2" from compressor to intercooler and I'll be going to 2.5" to match my compressor housing outlets.

Vadian, have you got any pics of the motor now?? be nice to see the mods you have done next to the kit as it came..
also what turbos are you using on the 440ci ls7??
Cheers
Chris.
PS. that torque curve looks really good!
