Block should have a model/ serial number.

Nope. Sorry.

Been answered. Basically it's a microphone. Generates signal based on
picking up sound. Tuned to pinging type vibrations.

Dunno.

I would think you would want to port match anyway, even if the
difference was minor.

Depends. What 1.8 block? The G60's?  Hmmmm. IMH Experience I have
interchanged 1.6/1.7/1.8 dists but this is by no means an answer.

Lots and yes. Thermostatic controlled oil lines fed to a cooler mounted
in the air stream with a rock guard on the front face.

Better for at least two reasons: better cooling for a stabilized
operating temp, reduced 'coked' (cooked to soot) oil in the bearings,
which leads to a shortened turbo life.

Dunno. Doubt that there isn't a diminished return after awhile. Colder
is better, bigger may not be better though.

We have some good turbo (or at least enthusiastic) people on the list.
Maybe you guys want to visit the VW Vortex forums and start a thread or two.
