Mating a Fiberfab Avenger GT kit to a Fiero (Page 1/2)
DroKnows JUN 22, 10:17 AM


I bought an Fiberfab Avenger GT kit from eBay. Currently sitting on a VW Beetle pan. I realized that I will be severely limited with horsepower and handling keeping the VW frame soI after comparing Beetle and Fiero measurements I got a 1987 Fiero donor car for the project. Has anyone on here done this before? I found a few pics off the web, so I know it has been done. I just wanted to hear some firsthand experience.

Haven't any experience, but would it not be easier to put in a 915 Porsche trans and any sort of higher torque engine with an bellhousing adapter?

I plan on putting a SBC in. Not sure about the transmission yet. MY concern is body fitment at the moment

There is an old thread where someone started doing the same thing and ran into lots of issues with wheel base, track width, and Fiero structure.

He basically cut the body down the center to make it wide enough for the Fiero, cut it along the length to make it longer, and hacked the vast majority of the fiero structure away.

VW based kit car bodies only have the vw floor pan to contend with.

Possible, but a huge undertaking...

Just so we can all see what you're referring to...

I heard a craft beer show once talking about their alcohol free beer. They called it "Why Bother?"

Thanks for the info. Wonder if the guy ever finished the project.

Here's a couple of Avenger - Fiero threads.

Cool, very helpful. Found these pics of the exact kit I bought, mounted to a Fiero.

Personally, I would go with the LS4 V8...Much lighter, and has the bellhousing shape for the Transverse transmissions. With a Iron SBC, you will be worse than 40/60 % weight distribution to the rear- spooky handling.....

They were in 2005-9 Pontiac Grand Prix, Chevy Monte Carlo/Impala and Buick LaCrosse.

How much structure is under the FG body? That will tell you how much Fiero structure you will have to cut away. Also, compare Wheelbase and track width to see how much the body has to be stretched to fit over a Fiero chassis.
