High tech turbo design plans See attached .tif for a sketch of what I'm doing with my Sonoma.. 
The more I think about it (and get input from others), the more sense it makes that you need as hot/high pressure exhaust as possible to spin that turbine. The nice thing about my Sonoma is I'll be able to put the turbo only 3-4' away from the exhaust manifolds, and I can move the cat to post-turbo.
In the case of the FBody kit, it's just sooo far back there that I don't really see how there can be much heat left. Was the testing done with hollow cats? That would seem to help.
Also perhaps heat-wrapping the exhaust system would help as well.

the turbo was designed and specifically built to be placed back there.
if you took an off the shelf turbo and slapped it back there then it would perform like crap.
at least this is what STS claims

I know that STS claims that, but what EXACTLY is changed or is propietary info?
I think Terry will pull it off.

I would imagine it's a small a/r
ball bearings would probably help too
hell, maybe they lube it with astro glide
anything to keep the exhaust gas hot will help, heat is what powers the turbo

I suppose a smaller turbo would help, as there will be the equivalent of less exhaust available to spin the turbine. It's funny because on their web page they claim this is somehow an advantage (which first set off my BS detectors). In the case of my
Sonoma the turbo is going to be pretty close to the heat source, so I don't anticipate any major problems. Famous last words for $500 anyone?

This is a picture of a T60 installed on a 4.3l.. The turbo is on the passenger side, to the front of the engine..
I think if you move the battery to the back, and make some room infront of the wheel well, you could put it there.. the problem is getting the exhaust out from there with a big V8 crammed in there..
heres what it looks like from the side.. out of the vehicle..
This is a T66
Edit--An internal wastegate would also be easier to work with!
I hope you have some money.. or alot of skill and time..
Keep us updated..

The nice thing about the setup is there is very little actually piping that needs to be done. The hardest part is figuring out how to take a 3" pipe and weld it to the square flange! I'll probably have my local magic muffler do all the piping; I'm estimating the piping (inlet and exhaust) will be in the $350 range, with a majority of that being the pipe from the turbo outlet to the throttle body. For now I'm going to skip the intercooler and keep it simple.
My budget for the entire project is around $1200, and I'm hoping to pickup ~75rwhp @ 8psi (it's a 4.3L V6). I have a few ideas for the fuel side, but if the turbo is efficient at 7-8psi I might need nothing more than a little maf translator.

Mach Performance makes a turbo kit for the 4.3l V6, for 5500 dollars..
It includes everything you need, except electric fans, and boost gauge..
This includes, Turbo, headers, wastegate, stand alone FMU, computer reflash, intercooler, BOV..
With a built transmission and 11psi you will be running 400rwhp..stock engine.. on the T61 turbo..
A guy has a fully built 4.3l, with the T66, hes still braking it in..
Mach Performance is also developing a turbo kit for the LS1..

edit- maybe they're working on a Turbo kit for the LS1..
I cant remember exactly..
But I know for sure they have an intercooled supercharger kit out now.. check the site..

With 7-8psi of non-intercooled boost I'd like to see +70rwhp (which would put the car at ~260rwhp). 400rwhp would be out of control in a little truck like this...

I would think there's enough room to fit a decent turbo in the engine bay w/o having to run under the passenger floor board. You will also need a scavange pump to keep the oil moving to/from the turbo.
If you do mount it like your diagram showed, a smaller exhaust housing will help. If you've ever seen a T3/T4, the hot side is very small. Helps spooling too.
