I found out that the carb 2.3L Turbo is covered in Ford's OEM Engine/Powertrain manuals for years '79 thru '81.
I decided to buy an '80 shop manual for my '79 off ebay because my experience with their service literature shows that later publication releases have many updates, corrections and revisions that are sorely needed for first year publication.
I also found that the blue '79 manuals had the Mustang & Pinto literature combined (yuck). In '80, they straightened their literature out a bit, combining Fox cars. According to some experts, the yellow Powertrain books that began in '80 seem better.
Thnx for thoughts
