Conflicting Specifications - Which is it?

[Matt Suffern]

Hi guys.  So I'm in the "education" phase of Type 44 investigation,
and I'm trying to nail down a few things about the car.

Basically there seem to be a couple of conflicts between the engine's
specs as reported in AudiWorld and Wikipedia:

http://www.audiworld.com/model/200/91-200.shtml
http://en.wikipedia.org/wiki/List_of_discontinued_Volkswagen_Group_petrol_engines#2.2_R5_20vT_162-225kW

Some things of note:

1. AW says 7.8:1 CR, Wiki says 9.3:1
2. AW says hydraulic lifters, Wiki says shim-adjustable lifters

Also, what's the general consensus on the sedan's weight?  AW says
3351 lbs, but that seems low...  3600 maybe?

Thanks guys.
