I just found a thread from '08 from "Mister" and thought it had some interesting pics of the 86 turbo concept. The Indy style scoop appears to be for looks but the one cool thing is the turbo intercooler built in to the rear wing. Stole some pictures....

Thats FREAKING AWESOME!!! i like how they did that!!!

Really nice detailed pictures, thanks for sharing

I would have never thought of the rear wing for an intercooler to go... is it actually a good place or it, or is it just for the look and cool factor?

For the thinking of the time, and considering that the spoiler on the Fiero was designed to be somewhat functional, it is actually a beneficial area to mount it. For one, it's located outside the engine compartment in an area that has a lot of air traveling over it, so the forced cool air factor has to be somewhat high. You'll also notice not only the custom stands to accomodate the charge piping, but also that the spoiler sits up slightly higher than stock.

The one off quarter windows would be great to have. The scoop looks like it will help with keeping the engine compartment cooler with the turbo. I am not sure about the life expentancy of flex pipes connecting the intercooler to the engine, but that was the only way system could function. Isn't this car an 87 because of the engraved intake?

Thats gangster... I need to see about doing an over the roof scoop setup like that on my IMSA that thing is a real PITA

Hrmm. Nobody noticed the different exhaust on it? Looks like single exit on each side, with separate mufflers. Wonder how it's all set up in there?

I didn't realize what a hack job that GM did on this car when I saw it in person. It is a great intercooler concept except for the flex tubing. That last picture, no wonder GM had problems with fires. Look how they are treating those wires. Why would they cut a notch out of the trunk wall?

The cut out in the trunk looks like it was cut for the intercooler pipes probably so they could close the deck lid completly without having to leave it open all the time (look at the pipes near the ceter of the decklid where they look to be clamped together)

Looks like the "turbo" is on the downpipe under a cover? Those flex tubes look like they would burst with any real boost

gotta love the foam sealer between the scoop and decklid ..real high tech

Those are aircraft hoses. They are reinforced with stainless wire inside and out, and are coated in silicon. They'll do the trick. Good start, just needs attention to details.

Well also keep in mind that it is just a CONCEPT car. The posted pics are from the 25th anniversay show. Do you have any pictures of the 1989 convertible? In your top picture it is in the upper center of photo. I'd like to see that car again. Thanks man!

These are copyrighted so I'll probably be asked to remove them but here is all I can find:

The reason why a turbo Fiero was never offfered by GM is that it would have made the car faster than the Vettes of the day. As it is a mid 80's Corvette is just marginally faster than a stock 2.8 Fiero so adding a turbo engine could have destroyed the Corvettes image.
I don't know why the convertible was never offered but it was probably developed too late in the game The Fiero came out in 84 and by 1987 GM already knew that they were discontinuing the car and probably scrapped all future plans for it.
Had both of these options come to be the cars value might have been far higher today.

That's the GM built 86 GT Convertible. It is here in Calgary with it's "younger brother", the ASC (American Sunroof Corporation) 84 SE Convertible. They were both purchased through Barrett Jackson by one of our members.
