[ba] Intro; quattro seeks abuse

I echo Steve's comments re: plopping in an MC instead
of doing an aftermarket turbo.

Over the years, I have driven many add-on turbo kits. 
They all suffer from one malady or another.  In
general, they do not have the driveability of a
"genuine" turbo motor.  One of the major differences
is that the MC engines included knock sensors, so Audi
could do a bit of boost push safely.  Even up through
1987, the N/A 5 cyl in the 4000Q had no knock sensor. 
And AFAIK, none of the aftermarket turbo kits included
one.  The other thing you need to consider very
carefully is whether you want to add a turbo to your
how old I5?

The 2Bennett $8000 upgrade includes an OVERHAULED
turbomotor.  For $2k more, you can even get the 20V. 
Those were the prices last time I spoke with them.

I saw one of the upgrades they did.  You'd never know
the car wasn't a turbo stock.  I have a few modified
cars here, and my experience says that if the car
appears as if it probably came that way, you'll pass
smog.  I even have a car with headers, two cats & twin
pipes, where stock was a single exhaust and single
cat.  They don't question it.  I'm convinced it's
because I did not go with bright shiny pipes - the
headers are just a tad rusty, as are the cats.

I can't answer the question about events.  The time I
might spend on rallies and the like is all spent
renovating the only house in the county that I could
afford that wasn't in a neighborhood where I was
afraid I'd get shot at.  Unfortunately I guessed wrong
on that last bit, having been shot at a few days
ago!!!  Thankfully it was a nominally benign weapon,
being air-propelled.
