As far as Porches go, the 1976-77 2.7 911S is the worst model you can get as far as used porches and engines. Not that its any bad, just that on those models, they bored out the engine to its max. Greater chances for problems and required engine rebuilds.
I plan to own a Porsche someday, either a classic or something new and FAST. A twin turbo would be perfect.
The SC engine started life in the Euro Carrera 3.0 in 1977 and was brought to the US as the 911 SC in 1978.
Even so - the problems with the 2.7L arent necessarily with the size, but with the different materials used within the engine that didnt react well to eachother when expanded due to heat.
That said, if you can find a 2.7L car in good running order, its a good bet that one of the previous owners had the engine rebuilt and solved the problem.
In any event, the 2.7L engine is a blast to drive when its in newly rebuilt form.
Good luck in your search - I spent 9 months looking for my first P-car and a little over a year looking for the second.
Finding the right one is the difference between a dream ownership experience and a neverending financial nightmare.
The new Turbo's are nice and
scary fast (especially the X50's) but if I had six figures to throw around Id go looking for a 904 or a 550.

Any questions, let me know.
