No, the rear mounted turbo setup I was talking about is being used on F body cars at this time. There are a few others, but basicly they put the turbo in the rear of the vehicle, and route pipes up front to feed the motor.
I've seen this done on GM cars, using the AFM in a blow through configuration, and it works great.
Takes a 375hp V8 SS Camaro, and pretty much lays down 450+hp with very few other mods. (Stock rwhp is in the range of 295 to 305 from what I've seen, and they then put down 450+ rwhp on the same stock motor.) I think the highest stock engine is just under 500rwhp at this time. I don't know how much more that engine can take, but the compression ratio is too high to run much more boost on 100 octane fuel.
On that same note, the lower compression Chevy truck V8's are actually better at being pressure fed. There is a Silverado truck with a stock LS3 V8 making over 650rwhp. (All wheel HP actually.) Very sick amounts of power, and not nearly as expensive as building up a 650hp 7M or Lexus V8 from what I can see.
Ultimate build from parts off the shelf would be a 7L LS7 V8, in alluminum, with 8.5:1 CR forged pistons and one nice GT40 turbo back where the muffler resides.
Use aluminum for the pipes, put the intake filter into the left quarter panel, with a nice vent in the side to feed it cool air, or close up the box, and vent it to the underside of the car.
Everything would fit under the stock hood, and place the engine back in the chassis somewhat, with the extra turbo weight over the rear wheels where it would help out with balance.
Anyone want to build a 50k MK3 Supra? LOL That's about what this would take to be done right, but it would be a very fast car indeed.
