The Fiero V6 2.8L engine produced a peak-corrected horsepower of 110 at 4500 rpm, significantly lower than the advertised 125hp. per dyno-testing of a stock 2m6.

The Fiero 4-cyl 2.5L engine produced a peak-corrected horsepower of 85 at 4500 rpm, significantly lower than the advertised 92hp. per dyno-testing of a stock 2m4.

Addition of turbo/superchargers has increased effective horsepower up to 30% without compromising engine integrity.

A 1985 Fiero Base coupe, or an SE Coupe that is nicknamed "2M4" (2 Seats, Mid-Engine, 4-Cylinder), has a 2.5-liter Iron Duke 4-Cylinder engine that produces up to 100 Horsepower, and a GT Coupe or an SE Coupe that is nicknamed "2M6", with the 6 as 6-Cylinder, has a 2.8-liter High-Output V6 engine that produces up to 140 Horsepower.


The 2003 Ford Mustang was rated at 190-horsepower



Stock 140 HP , 170 lbs of Torque


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


The standard stock Chevrolet V-6 engine has 160 horsepower. The horsepower of a V-6 engine can vary greatly, due to many different factors.



185 horsepower , according to my Consumer Guide book


87 thunderbird turbo coupe came stock with 190hp


Stock from the factory the 3.0 V6 has 210hp


Best top speed for a stock V-6 Fiero: 135 mph Worst: 115 mph Both Fieros were '85 GT's, the latter with an automatic transmission.


This engine will have seven injectors. 6 are the running injectors and there is a "Cold Start" injector.


it should have around 310 hp at the rear wheels.



It can come with either a Getrag manual 5 speed, or an automatic 4 speed with overdrive


Fieros came with 2 differnent stock motors, a 2.5 liter 4 cylinder, and a 2.8 liter v6


Any correctly running Fiero can beat any stock S10 One is a pickup and the other a sports car They both use the same engines. Nuff said.





The 3.8 v-6 with a 5 speed manual tranny puts out around 210 stock


Stock Horsepower is around 39hp.


i think it puts out about 365 horsepower stock


Stock horsepower on a 350 varies from 145-370.
