Super Piston Slap: The Buick-infused Fiero at LeMons

Perhaps you already know a little about this car from a previous post, but let’s look a little deeper into what makes an engine swap in a Fiero so positively epic.

First off, if you don’t know about the Pontiac Fiero, shame on you! This is one of many half-baked efforts from General Motors that deserved a better fate. Let’s face it, the Chevy Corvair coulda lived to see numerous upgrades and cult classic success, sparing us from colossal money pits of premium compact car hell, like the Mk V Volkswagon Golf. The multi-cammed, custom bodied Corvette ZR-1 (with a dash) was far too excellent to die, although it has finally come back with a vengeance in a slightly less unique guise. The Cadillac Allante finally made some sense when it received the Northstar V8 in the last year of production, but the Fiero was the worst sin a neglected GM product faced. The staggering number of upgrades in 1988 and the clean “Formula” trim level made this ride a potential success…if that wasn’t to be the last year of production.

Thank goodness for people who keep the flame, and raise up the heat. The Buick “Fireball” 3.8L V6 is a fun and worthy upgrade, as seen here in this LeMons racer that we all ogled during the BS inspection. Of course, the team’s wicked Ferrari theme didn’t hurt, even the wheels looked great! Adding the hood vents from a Trans Am GTA (correct?) and an impressive roll-on red paintjob with catch phrases in Ferrari’s own font absolutely sealed the deal. Opening the hood while doing my judge-ly duties, I remarked, “wait, that isn’t right? Is that a…

…and before I could fully digest the sheer volume of awesome presented to my eyes…

It’s a 3.8,” said a team member. Well, that just made my day. The 3.8L V6 is a gutsy, durable and coarse little mill, compact and easily fitted into the Fiero’s little frame. The later model (Series II and up) mills give you way more grunt than the 60-degree pushrod motor that came in a factory Fiero, and upping the ate with the (roots-type) supercharged Buick V6 would be absolutely wicked. Too bad this one is naturally aspirated! And while this motor (and any mid-engined car) has a serious uphill battle in an endurance style, crapcan LeMons race, this type of automotive expressionism is wholly encouraged and applauded ’round these parts.

Ready for more? We have another Fiero motor swap that’s worth a closer look, coming soon. In the meantime, you know I had to drop a little LSX love, even if that won’t fit within LeMon’s $500 budget.

Yeeeee-ha! LS4-FTW and I’m headed back to the races this weekend!

    Electric power steering was available on the final model year Fieros. Along with a suspension that was actually designed for the car and not a collection of parts bin hand me downs. Just another example of GM losing interest in a vehicle after getting its problems worked out.

      Fieros never had power steering as a option. Check your sources.

    The Fiero engine bay is big enough to accommodate many engines. Most are fitting V8's in there, but, personally, I think V6's are a lot cleaner looking. The problem would be wiring up the electronics to work. I understand the old Cadillac 4.9 V8 is a direct bolt on to the existing Fiero transmission without any adapter plates required. So that might be the easiest transplant. Wiring harness not being considered.
