So how does Subaru do it? Some sort of air ducting/heat shields? The STIs have the air intake on the hood, but arnt other versions of the car turbo as well that do not have that style hood? They just lack the intercooler?

They do indeed. A purpose designed ram scoop to shove air thru the intercooler. No hood scoop, then either no intercooler (not needed until you broach 10PSI after all...) or the intercooler is mounted in front of, or beside of, the radiator. I run 8PSI without an intercooler and all is just ducky...
At sea level, the boost would be much closer to 9.6PSI. Still good without an intercooler.
Is an intercooler a good idea regardless of the boost level? In a word, yes. As long as it actually cools the air charge and not heat it. In any event, the heat exchanger (to call it what it is...) must be in a stream of "cold" air in order to function. Cold being defined as not as hot as the under hood temperatures.
None of this is Rocket Surgery nor Brain Science. It is just common sense. Put a heat exchanger into a hot environment and it will collect heat. Sort has to, yes?
Unless the laws of thermodynamics have been repealed since I last looked, energy (in any form) will tend to move from the higher potential to the lower potential. Water that is up hill will run down hill, heat moves from hot to cold, electricity moves from well, you get the idea.
Do I want to install an intercooler into my setup? Absolutely I do. Is there room for one? Absolutely not. So... I am nearly at the practical limit for safe boost. I could add a couple of pounds and still be OK but that would entail replacing the compressor I have with on that is larger. The compressor is at it's operating limits.
IMO Supercharging is the best solution for vehicle that go off road as boost can be had at any engine speed above idle. Turbochargers, again IMO, rare best suited for on highway usage where the engine routinely spins at a respectable speed. No exhaust flow, no boost with a Turbo.
In years past, I have ran both and although the Turbocharger is the hands down more efficient way to make boost, there are practical impediments to it working at the engine speeds we see.
Which is why there is a Supercharger under my hood.
Well, that and the near enough to call it 300 ponies...
I plan to be at the M&G on Saturday (unless I become ill yet again) if anyone would like to see how my rig runs. It does not drive like any XJ you have ever driven before. You might say it is subtle in the power delivery.

You ought to sell tickets to drive it.

Nah... It would be interesting to put it up against a Stroker for a drag race though...

Not sure what to think of this one.. Could be awesome, could be not. Not a fan of the rear chop / cage though.

On looking at the pictures some more, I hereby retract that statement. :nosmile:

I actually look again too, and the front pinion isn't as bad as I feared, assuming its a single cardan shaft, the top/bottom angles might be paralell - steep angle for a single cardan, though... looks like and OK rig, but with some questionable craftsmanship. why would you bother swapping in a D60 front and go with a low-pinion model? :eyes:

It was not.. but it had a lot of the same wording.. *Must see to appreciate*..... The one I was looking at he was asking for $12k........ yea no.
Oh Lordy. This it? http://denver.craigslist.org/cto/4427476676.html
Maybe they're using the same math as these people:
http://denver.craigslist.org/ctd/4478323402.html <-- Oops, extra zero...
http://denver.craigslist.org/cto/4471000828.html <-- A "new" motor = never getting that money back
