The Jetfire used a sidedraft single barrel version of the 2-barrel Rochester carb (itself half of a Quadrajet). In spite of the most complex fuel/air control system ever put on a production car to that point, the system was simply ahead of its time and not up to the task assigned to it. However, GM learned an enormous amount from these early turbo engines and transfered much of what they learned to the turbos of the late 70's and early 80's. For instance, even though the Buick 231 V-6 is only slightly larger than the Jetfire's 215 V-8, its turbo is vastly superior and its carb flows 3 times the CFM as the Jetfire's. So I wouldn't rely too much on adding injection to one of the GM turbo units like I have been advocating.
