Some were even turbocharged and are referred to as the Turbo I, Turbo II, Turbo III, and Turbo IV. The plain fuel injected 2.2 L competed with Ford's HSC 2.3 L engine in the Tempo and Topaz, using very similar bore and stroke. Ford's HSO engine competed with the 2.2 Turbo versions.

In case you needed a more direct answer, the LeBaron convertible in 1988 had the fuel-injected, standard-output version of the 2.2L SOHC engine. According to Wikipedia (I don't have my books in front of me), the hp claim for that engine is 99hp.
