Remote mounted turbo
Saw an article in Turbo and High-Tech Performance Magazine on Squires Turbo Systems remote turbo systems www.ststurbo.com. Their web site has a Q&A section to address the skeptics questions.
They seem to focus on the bigger engine vehicles where the engine should have enough grunt to make up for any turbo lag. They have done LS1 and LT1 camero/firebirds. The turbo is mounted behind the rear axle and in place of the muffler. If you remove the spare, there is lots of room for one on a C4.
My bet is that he has to size the turbo much smaller, than the typical install, to compensate for reduced exhaust volume (exhaust is cooler that far back). It is interseting that he claims that the long intake tract acts as a intercooler without the pressure drop of a intercooler.
The Sport Truck article that is included as a link on STS's web site does a good job or reviewing/testing the product. I noticed that the dyno numbers fall off quicker for the turbo than the normally aspirated baseline, but the turbo numbers still look good.
I am a little skeptical. Interested in thoughts.

I have been watching that set up on the F-body forums.
I saw one of the test cars (firebird) on a trailer around the corner from work in a mall parking lot. I dont know what it was doing out here as it had Utah plates. My only guess is that Duttweiler (turbo V6's) shop is about 15 mins from here and maybe they were playing with it over there on a dyno or something.
This car looked pretty seriously set up for drag racing, it even had some intake vents in the quarter panels to get the air to the turbos I asumed. I wish I had my camera on me when I saw it.
The vette would have some room in the back for the system just pulling the mufflers, I think there is an issue with finding room to route the exhuast back to the turbo, and the discharge pipe(s) to the front of the car.
Maybe if you had a single exhaust pipe to the rear, and a single discharge run to the front it would go in easy.
I suppose the oil lines would be another issue. I dont know much about oil pressure and flow, but would think running a line to the rear of the car would drop some pressure maybe?

my buddie did one of those set ups on his 03 GT mustang it sucked bad,his Turbo kept siezing up,they run a electric oil pump to return the oil from the turbo to the engine.when it worked it was crazy fast but he had lots of tuning issues.Squires did not make his kit they pieced it together from different people,but he did get the oil pump from squires,500.00 bucks.they have a LS1 car that they claim like 700hp to the ground but I have yet to see it running around here in Saltlake.the system works good on cars that have a single exhaust from the factory,easier to plum it,if you do this system be ready to run good gas and do some bigger injectors also,and turn your timing down alot,or run a boost timing retard box from MSD.

I took a long hard look at one of the STS systems Friday on a regular cab Chevrolet truck. He drove the truck to the shop in a driving rain storm and I was interested to see when he pulled in how much water was on the inlet filter. I thought these systems would suck up water but I was wrong the filter was dry. The kit seems kind of expensive for what you actually get. There is not much to the kit, it could be built with very little money. It also came with no blow off valve, and no tuning. The truck sounds great though with no muffler, plenty of turbo noise.
