Ken,

Keep thinking.  I'm interested too in these.  I pmailed a listee in
Alberta who was a welder that manufactured exhausts for turbo additions.

We decided to freely associate our concerns and see what transpired. It
seems the concern was to the extra load on the studs/thread mount on the
crankcase halves, perhaps keen serts or heli coiled. Anothor concern was
the load on the heads, particulary around the spark plug and head boss,
 the  two sites that current heads crack.

The oil return was an issue, I think I was looking at the oil fill pipe.
 Seems that Frank Gunthaur (sp) had a sump and pump type of comment at
one time on his INLINE turbo project, not sure.

I also had a Subaru WRX  reseach angle to get hints  for the way that
they did their turbo. Seems the length of run from far side cyclinders
caused a bit a an exhaust pulse issue so that one of the pipes came into
the turbo colllector out of firing order sequence.

The intercooler in the area you suggest is my favorite pick too.  As for
fuel supply, the adustable fuel pressure regulator from CB performance
is what I run, 50 PSI, and back off the wiper arm on the AFM until the
O2 maps correctly again.  Our consensuss was to just see how much boost
this would support via the O2 fly it and watch it method.

Sincerely,
