The Tempo was designed to use a four-cylinder engine, but all production of Ford's 2.3 L Lima OHC four was committed to other product lines. At the same time, the 1983 end of life of Ford's 200 cubic inch Thriftpower Six inline six left unused capacity at the Lima Engine plant. Ford developed a four-cylinder engine that shared some features of the Thriftpower six, topped with a new cylinder head and using other new technologies, while repurposing as much tooling as possible at the Lima plant. To maximize use of existing tooling the new engine shared spindle spacing where possible with the Thriftpower six, resulting in similar cylinder, crankshaft, and tappet bores, as well as crankshaft journal diameters. Reliability and durability were key design goals for the
