Got on this kick yesterday looking at Popular hotrodding online.

A remote mounted turbocharger that would fit my ls1 camaro, BUT I
thought after looking at the web page why not on the Pacifica. Remote
mounted turbo. No kit for the pacifica, but from what I see they have
looks very easy to fabricate a setup.

And looking around on the net, there's not much performance stuff for
the 3.5L But after looking at http://www.turbominivan.com was thinking
that a turbo would be cool on the Pacifica. Shockingly, the wife
disagrees.

Saw a link to a Pacifica called "Oblivion"
http://www.oblivionperformance.com/oblivion_pics.html but way too over
the top for my tastes. Interestingly enough, they somehow stuck a
freakin Novi supercharger in there.

You might be interested in this thread on the 300M Enthusiast's forums:

Topic is remote turbos specific to the 300M which as you know, uses the
3.5L. STS is mentioned in the discussion.

Thanks, Bill. Checked it out and will watch the thread.

I'm skeptical you can mount a turbocharger so far away from the engine and
then get 5psi at the throttle body. BUT 4 Guys Garage is doing a show on it
Dec 30th (for the LS1 chevys, anyway)

If it works, it's VERY cool. Longevity etc I wonder about. I would hate to
drop 4 grand worth of parts on the highway. And the air intake being behind
the rear wheels doesn't thrill me at all. Water infiltration seems like a
huge issue. Less on a truck though. The real beauty of this though (IF it
works well) is not having to find space in an already cramped engine
compartment.

There is a turbo for a Pacifica. It a has the same engine at the 300m.
So search for a turbo charger for a 300m and you will find it. It is a
3.5L engine that is no different the the regular 3.5L engine.

When Chrysler delivers a turbo option, it has specially engineered the
engine literally from the ground up. Many specifications are different
from outwardly similar non-turbo engines:

Valve timing is different, requiring special camshaft.
Looser tolerances to allow more piston expansion to avoid seizing.
Larger oil sump capacity.
Fuel injection system calibrated differently and may differerent
configuration altogether.
Cooling system enhancements.
Ignition timing profile different.
Exhaust system larger bore.

I no doubt have missed many other mods to the power train they deem
necessary to maintain durability and reliability and to optimize efficient
power delivery.

Demanding from an engine up to 50% more power places it under enormous
additional stress. Just tacking on a turbo is asking for trouble.
