Why it can be made fast:
* Lightweight Chassis: The Fiero's biggest advantage is its lightweight design. This makes it inherently easier to accelerate and handle well, especially with power increases.
* Mid-Engine Layout: The mid-engine placement contributes to excellent handling and weight balance, further enhancing performance potential.
* Large Aftermarket Support: Because Fieros have a dedicated and enthusiastic following, a substantial aftermarket exists providing numerous performance parts, from engines and transmissions to suspension upgrades and body kits.
Modifications needed for significant speed increase:
* Engine Swap: This is often the most significant modification. Many Fiero owners opt for more powerful GM V6 or V8 engines, or even other brands like Honda or Mazda engines. This is a major undertaking involving significant fabrication and engineering.
* Transmission Upgrade: Stock transmissions may not be able to handle the increased power from a larger engine. Stronger transmissions and potentially custom drivelines are usually necessary.
* Suspension & Handling Improvements: Upgraded suspension components, including stiffer springs, shocks, sway bars, and possibly a custom adjustable suspension, are critical to handle the added power and improved speed.
* Brakes: Upgraded brake system is necessary for safer high-speed driving and improved stopping power. Larger rotors, calipers, and higher-performance brake pads are often needed.
* Cooling System: A more powerful engine necessitates a more efficient cooling system to prevent overheating, especially during high-performance driving.
Caveats:
* Reliability: Significant modifications often compromise the reliability of the car. Proper installation and careful maintenance are paramount.
* Cost: Making a Fiero truly fast is expensive. The cost of parts, labor, and potential unforeseen issues can quickly add up.
* Structural Integrity: The Fiero's chassis, while lightweight, is not necessarily built for extremely high horsepower. Modifications exceeding a certain power threshold might require chassis reinforcement to prevent structural failure.
* Handling: While the mid-engine layout improves handling, significant power gains can make the car difficult to control without proper suspension and tire upgrades.
In summary, a Pontiac Fiero *can* be made fast, but it's a complex and potentially costly project requiring considerable mechanical expertise and a commitment to ongoing maintenance. The level of "fast" achievable is ultimately limited by the budget and the owner's willingness to address the inherent challenges of modifying an older, relatively lightweight vehicle.
