There is a great article on all 3 versions of the 2.2 911 (T, E & S) in the June 2010 (#183) Excellence magazine. In an in depth report on the nuances of all three.
The author selected the E model which makes 155 BHP which he thought was funner and more responsive than having to go deep into the rpm's to call the S's horses up.
A great article, putting one together is an expensive proposition, do your research.
Good Luck, I have a 911E case that I am wanting to resurrect, but it may just be easier to drop a 3.0 or 3.2 in my next project.
