Turbocharging the original engine, the design of which was finished in 1974, was impeded until 1985 due to restrictions of the original design.[1] Heat flux issues with the aluminium head and swirl chambers were eventually overcome, but did slow down development.
First direct injection models also appeared in the mid-eighties.
Additionally to the Fiat designation 8140 some engines got a Renault tag (S8 for indirect injection, S9 for direct injection).
2.0 l version
In the early beginning there was a 2.0-liter (1,995 cc) four-cylinder 65 PS (48 kW), called the Sofim 8144.65. Alongside the 2.4-liter version it was used in light commercial vehicles like the Saviem SG2, OM Grinta, and the Fiat/Iveco Daily, as well as passenger cars like the Fiat 131 and 132 models.[2][3] It also saw use in the Fiat Campagnola.
2.4 l version
The original 2.4 l big block displaces 2,445 cc (149.2 cu in), bore x stroke was 93 x 90 mm.
