Little Engine That Could!
majority of Pontiac Fieros were built with the cast iron, pushrod, low
rpm, 2.5L four cylinder engine. The Iron Duke or Tech 4, as it was
later called, was a simple engine with more potential than most of us
realize. Here is where you can start to appreciate one of the
workhorse engines which are all too often ignored and maligned.
This page is not meant to send you out looking for a four cylinder Fiero to build a performance car. The 2.8L V6 Fiero offers far more "Bang for the Buck" since they cost only a little more and have 50% more horsepower. This is aimed more at the owner who wants to try something different, BUT EXPENSIVE, like building an SD4, or someone who already has a 2.5 and would just like to try some of the more modest suggestions to make their cars more enjoyable.
