Ford Pinto engine
The 2.0 litre version was a narrower-bore version of the original 2.3 liter "Lima" four. Bore and stroke are , respectively, for an overall displacement of . This engine was installed in the 1983-1988 Ford Rangers and in some Argentinian Ford Taunuses.The Ford Pinto used the OHC version, a 2.3 L (2301 cc) unit introduced in 1974 which has a bore and stroke. This version lasted until 1997 in various guises. The earliest units produced 66 kW (88 hp) and 160 N·m (118 lb·ft). This engine has also been known as the Lima engine, after the Lima Engine plant in Lima, Ohio, where it was first manufactured (it was also later manufactured in Brazil).
Ford I4 DOHC engine
The engine was originally designed to replace the 2.0 L OHC Pinto engine, derivatives of which had powered most of Ford's four-cylinder rear-wheel drive cars since the early 1970s, and which was by that time lagging behind the competition in terms of power output, efficiency and refinement. Equipped with a newly designed twin-cam cylinder head but still only 8 valves, and a "square" 86x86mm bore and stroke, the new I4 was launched in the Ford Sierra and Scorpio, mated to either the also new all-synchromesh MT-75 5-speed manual transmission or the existing A4LD four-speed automatic. The engine received mixed reviews, being seen as an improvement over the Pinto, but not the leap forward one might have expected.
