Audi 90 engine types

[gfl@cc.bellcore.com (grant f lenahan)]

Just to clean up some confusion from earlier
posts:

90Qs had one of two engines: the 2.3l 20V and the 2.3l 10V
Both were naturally aspirated.  There was NO turbo,
nor, in contradiction to the earlier posts, was the 
20V faster than the [nonexistent] turbo. :-)

I assume you are interested in USA models -
turbos did exist, at least in coupe models,
elsewhere.
