Smart people want an efficient Fiero & low operating cost,High MPG,,,gear heads like my self want something else & often drive in an irresponssible manner & go to fast. a Fiero performance engine is a aluminum block 750 horspower SBC, the man pedal is hanging
on the left handle bar of a 9/10 second E.T. motor cycle a real rush,i can no longer handle a 10 second M.C.quarter miler old age!! 2 year ago I rode one of the 10 second monsters ,now that was scary real performance
I owned an 88 fiero 5 speed duke & it was as much fun to drive as my slightly modified 86 GT 2.8.I own now .It was more than fast enough ,the 84/ 86 duke is underpowered,,many men do not want to have bigger & faster & spend $2000.00 on thier engine compartment so they can hit speeds of 70 MPH & creep in tracffic.
I have found the Fiero is a fun sporty car to own & drive with a Duke ,I love the look of the Fiero . I replaced my Porsche wth an 88 Fiero 5 speed Duke,,(at one time,I had money ), just had to own a Porsche got carried away,,911,944 & 924 there was no noticible difference in the handling & fun driving around town, Of course all the Porsche were faster ,I had 3 at one time,but for 99% of driving there was not any Difference,, the look at me,, look at me false pride was the only difference
the 88 duke ran a blistering 10.2 to 10.9 second, 0 to 60
but many got 38 to 40 happy time MPG hwy
if you want to get 45 mpg HWY from a 87.88 duke Fiero ,install a vacuum gage
if you drive long distance in a 4 speed V6, the vacuum gage will also save you money
The Fiero store Performance TBI was a bored out TBI as show on page 20 of the 2005 catalog
the 25% power increase was just what the story said,, realistically 15 to 18 % was more inline
the fastest Fiero was the super duty 4, with the lowest power super duty running an 14.7 quarter mile ,6.3, 0 to 60
there are men who want a duke in a fun to drive Fiero & some do want more power,but the engine swap is not in thier future
of course we all dream of the smedling 750 horsepower tremec Fiero.Im DROOLING
thanks Fierosound for the duke owners
