  Stick with 86 or newer. Use the Quattro engines because they have bigger
  valves, more torque. I believe there are 1990 or newer 20 valve engines too,
  that's the way to go. 135 to 150 HP stock sure is nice.  >>

 FWIW, the Quattro engine is the turbo engine.

Hi Chris, I have an 87 Quattro 5000 non turbo, (bigger valves).  I prefer the
non turbo over the turbo. Audi 4000 quattro's are the same, non turbo, so are
Audi 90 and 80's.  Quattro doesn't mean turbo. Also the VW Quantum syncro is a
Quattro 4000 or non turbo 5000's. The non turbo 5000 Quattro's have the big
headlights like 89 - 91 100's, front wheel drive. The turbo 5000's and the
turbo Quattro 5000's have the sleek longer rectangular headlights like on the
89 -91 200's. There are Audi 200 20 valve turbo's too with 215 HP.  Also a
limited addition 1993 100 20 V turbo sport with around 250 HP's.  Hope this
clears things up a little.
 See ya, Michael
