That is the route I am leaning toward right now.  This is a relatively heavy
and boxy car, so it will take some horsepower to shove it down the highway at
70MPH.  If it is always on boost at cruise speed, then it would be more
efficient if it also has an intercooler.  The trick will be getting the turbo
clocked differently so the compressor outlet is not pointed straight at the
intake and then building the custom plumbing.  Does anybody have a source for
hose and thinwall aluminum tubing for building IC systems?
