Project Overview
This Pontiac Fiero GT project began as a barely running 2.8L V6 car with a broken clutch line. After initial repairs and suspension upgrades, the car spun a bearing in 2020, leading to an ambitious Honda J-series V6 engine swap. The project features extensive CAD modeling, custom engineering, and uses a 2006 Honda Accord V6 as a donor vehicle.
