Thanks guys, the lines were pretty easy to do, but got
to be kind of expensive.  Here's what I did,

Oil feed line:  Tapped the filter housing with 1/8"
NPT (pipe thread), then used a 1/8" to -6 adapter.  I
drilled out the steel adapter I had because the hole
was pretty small.  I wanted to get it as close to the
stock size as possible.  From there I used a 120
degree hose end, -6 hose, then a 90 degree hose end.
The turbo is threaded for 1/8" NPT, so another -6
adapter was used.

Oil Drain Line:  This is the only hole on the turbo
that isn't threaded and requires a flange. Turbonetics
offers Drain flanges that are threaded for 1/2" NPT.
These conveniently fit the block and the turbo.  I
uses some barb fittings and some -10 hose that I had
left over from my oil cooler to connect the two
flanges.

Coolant Feed Line: Clamped some -6 hose onto the
outlet barb in the block, then strait to the turbo
with a 90 degree hose end to a -6 AN to 3/8" adapter
that screws into the turbo.

Coolant Exit line:  I cut the hose off the fitting
that was on the coolant exit flange.  This exposed a
simple barb fitting that I slid some -6 hose over and
clamped it down.  The hose fits behind the cam belt
housing just fine.  From there I used a strait -6 hose
end connected to a 45 degree -6 to 3/8" NPT adapter
that screws into the turbo.  This is the closest
fitting to the EM, and this combo gave me the most
clearence.

The fittings from the old turbo are pretty much
useless, sorry Ben.
