The 2.8 V-6 engine was first used in the Fiero in the 1985 GT. It was called a 2.8H.O. engine and had 140 HP. It was the same in 1986. However, the same engine was used in other GM cars but had 130HP.

In 1988 Fiero horsepower was reduced to 135.

how ever they say 140 HP but dyno tests proove that the 86 fiero gt has 200 HP
