The most powerful Pontiac Fiero variant ever offered was the GT, which produced a rather mild 140 horsepower from its naturally aspirated 2.8L L44 V6 engine. For this reason, engine swaps in the small, mid-engine sports car have become fairly common.
We’ve seen all sorts of engines dropped in the Pontiac Fiero, from 350 Chevy V8s to Volkswagen VR6 V6s, however a Fiero-obsessed YouTuber recently put together a video explaining why the supercharged GM 3800 V6 engine is in fact the superior motor for this two-seater.
The YouTuber, who goes by Toys4Life, says the acceleration of his own supercharged 3800 V6-swapped Pontiac Fiero is “insane.” While he doesn’t provide any acceleration figures, the clips of his Fiero easily smoking the tires as he accelerates from a dig is evidence enough of this car’s capability. He also showed a clip of him absolutely smoking a second-generation Cadillac CTS-V sedan at the dragstrip – a bonafide performance sedan that produces 556 horsepower. Not bad for a little Pontiac, right?
Our Pontiac-obsessed friend also says the supercharged 3800 V6 sounds great from both the exterior and inside the cabin, and as fans of a loud supercharger whine, we definitely have to agree with him on that point. There are other advantages to this engine swap, too, including low costs, reliability and, perhaps most importantly, how easy it is to modify. With an aftermarket intake, a different exhaust, a ZZ Performance camshaft and a smaller pulley that produces a bit more boost, this owner estimates his car produces around 380 horsepower or so – which explains how he was so easily able to leave a Cadillac CTS-V in his wake.
