So HOT exhaust drives the turbo.........

We've been considering doing that for awhile to my buddy's Jeep. I would NOT run a remote-mount turbo. The farther the turbo is from the exhaust manifold, the more energy the exhaust can lose before hitting the turbine, meaning you lose throttle response and peak numbers.
On an engine like the 4.0 with the intake and exhaust manifolds on the same side of the engine, I'd just put the turbo right up there between 'em. Have a header with runners maybe 1.5' long average coming straight out from the head just far enough to get around the intake manifold and then have less that a foot of pipe to dump the turbo into the intake. Then run water/meth to cool it down isntead of an intercooler. JMO.
Keeps the frictional flow losses low, keeps the turbo high away from water/dirt, and keeps the system as simple as possible...
