My brother has his Mustang tuned by this guy in Winnipeg. He's currently working on converting a Saturn Sky to an LS2 engine. My brother said he's nearing 1000 hp or something crazy like that.
I thought some of you might like to see the pictures:
Take note of where the turbos are! In the rear! That's really weird.

So does anyone know what the benefit of having the turbos in the rear like that is? And where the heck does the exhaust go? I couldn't see an exit pipe anywhere.

The benefit of having the turbo in the rear is that the turbo is less efficient (by the time the exhaust reaches it, things have cooled down so it's not expanding as much or moving as fast now), the throttle response is horrible (air has to travel the whole length of the car), the lag is terrible (because of length of piping the turbo takes forever to spool, and it has to build boost in that huge pipe), and you have to worry more about puddles (if it manages to get the exhaust side hot, and you run through a good puddle, expect a cracked housing from the thermal shock.)
The turbo can dump right out of the turbine exit, since it's already at the back of the car.
STS turbos are so retarded, whatever you gain in "ease of installation" you lose in performance (and then some) versus a standard setup. There's no reason to not just figure out how to fit the turbo in the engine bay.
It seems odd that they'd put the turbo back there on this Sky then if there's so many problems with that kind of setup. My brother said the guys at the shop really know their stuff.

Could be a room thing, could be a don't care or don't know any better thing.
STS seems to do a good job of helping people not realize the problems with that kind of a setup.

It might make a big differance excpet its already an insane ride just with the LS2... probally has no traction anyway so the slow spool wont bother in a car like that..and there probally isnt anyroom.. not exactly a large car to begin with .
I think its totally sick, I would never do that to mine.. I like to be able to drive in the rain sometimes.

Your right, thats the big problem, traction. I have an LS2 conversion and all I can say is I need more rubber on the ground. It'll spin them with not alot of persuasion in 1-4. I can only imagine how this will be.

Hey Man, ignorance is bliss for me.
I have driven STS Turbo SRT10s, ZO6s, Camaros, GTOs, etc... I can tell you that with a big V8 and reasonably sized turbos, turbo lag is not a problem. My SS Camaro stock put out 305 horse power to wheels stock, with a single Garret 60-1 P Trim I made 416 rwhp on 5 PSI and 505 RWHP on 8.5 PSI. I drove that car with the STS kit for a year with out any problems (other then 2 new rear ends, and a new clutch . I do know that a STS kit will beat the crap out of any supercharger kit for PSI gains or 1/4 mile times. I've seen 4,000 pound GTOS run high 9 second 1/4 mile times with a single GT76 turbo STS kit. in
Set up properly a STS turbo kit will work as intended on a car with a LS2. On a 4 cylinder they suck, on a big V8 they rock. Believe me I know and so do a number of other top corvette shops around the country.

Pros of a rear-mount kit:
1. Short of relocating the heater box, battery, wiring harnesses, and rebuilding the lower engine cradle it would probably be almost impossible to do a V8 TT set up in a kappa. It looks like the installer is running the charge pipes up through the frame rails and utilizing the space where the muffler used to be for the turbos.
2. There is no need for a muffler or exhaust past the turbos, 0 back pressure beyond the turbos helps to make up with the length of the exhaust running back to the turbos. It will also sound really wicked. I’m sure he’s adding exhaust tips like this:
3. It is much easier to handle the heat up front since you can use the stainless manifolds rather then a coil of red hot headers tubes and turbos. Almost everything in the engine bay is plastic and would need to me moved or protected with front mount turbos.
Keep us informed on updates with dyno graphs or even a video, I would love to hear that Sky! STS has talked to Mallett about offering a STS kit along with his engine install, I’m not sure if it got anywhere.

It's better than no turbo at all but I'd not want to run oil lines all the way to the back of the car. It's an engine life issue if they get snagged, and a hell of a safety issue if one starts to leak and you drive through it.
If heat is such a big issue, ceramic coating and heat shields are easy to do and will improve power production and turbo spool.
The reason it would "suck" on a 4-cylinder and not on a big V-8 is a big V8 has good torque to hide the slow throttle response from the rear turbo.
