1.8 Vs. 2.0 Revisited AKA why 1.8 instead of a 2.0 head

[Rabbit16v@attbi.com (Rabbit16v)]

Wasn't talking about the 1.6/1.7/1.8 engines, we were talking about 1.8L and
2.0L 16vs and in specific 2.0L 16v throttle body.  I don't believe they have
an egr so I guess it would be torque or fuel efficiency.
