Turbocharging the original engine, the design of which was finished in 1974, was impeded until 1985 due to 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).
