Hello and my name is Chris! I am a 22 year old Union Sheet Metal worker. I was born and raised in West Branch, MI and recently moved to Georgia, currently in Powder Springs/Marietta area. I have always had a passion for the outdoors, and anything with a motor. I recently picked up an abandoned project from a really nice guy I met down here. Below is a long story about my history, so dont feel obligated to read it. WILL BE MAKING CONSTANT UPDATES! TONS OF UPDATED PICS BELOW, AND THROUGHOUT THE ENTIRE THREAD! SOME VIDEOS ON PAGES 2!ALWAYS MORE TO COME! FRIENDS SRT-4 ON PAGE 9!YELLOW CHOP-TOP 3800 FIERO ON PAGE 10!MY NEW 1997 BUICK REGAL GS STARTS ON PAGE 11!The car: 1988 Pontiac Fiero Formula edition (1 of 5,484) started its life in Florida and belonged to the parents of the gentleman that I purchased it from. His older brother drove it to highschool and then He purchased the car for himself in 1998. In 2000 he gained interest in a new unheard of idea... Take the powerplant from those awesome new Pontiac Grand Prix GTP's and put it in a Fiero! That is where the adventure began. Not too long after he located a donor car from a salvage yard. A 1998 Pontiac Grand Prix GTP that was totaled in 2001, with 30,000 miles. While going to college he worked on the fabrication the wiring harness, and creating ideas for custom motor mounts. Sadly, before the project could be finished, he graduated college and moved away to start a new job. Ten years later he has moved back to the area, and decided that it would be best to pass the car onto someone who has the time and interest to finish it. This is where I come in... Through highschool my best friend Ray, myself, and his father had a project car we worked on. It was a 1994 Grand Am GT coupe. (some car! I know right lol) we tinted the windows, lowered it, put some rims on it, etc etc. The car originally came from Texas with a 3.3L motor and I think it lasted about 1,000 miles before we blew the top end of the motor from constantly burning out and racing around, so his father being a retired GM employee came up with the bright idea of putting a Series II supercharged 3800 in it. That winter we began the project, and to great surprise that spring it rolled out of the garage (I have only ever seen any evidence of one other of these swaps being done), and yes it was fast! It would pull 0-60 in around 5.1 seconds. Later that year we gave it a nice black paint job, it was a true sleeper! Then one day on our way down to visit his dad and tinker on the car it lost all power. We got picked up and headed back north the get our rollback and take it to the garage to see what happened. The next day we headed back down I75 to get it, and it was not there. We assumed it had been impounded, but after a couple phone calls realized that the car had been stolen, not towed. We never did see it again ;( The next year Ray's dad had a stroke, and is not able to do any wrenching. I went to look at this Fiero the day it was posted on Craigslist. Instantly I fell in love. It reminded me of the Grand Am we had built, but it had an even sportier quirk about it... I told the guy my story, and hung out for a while, and drank a few beers. We decided that the next day I would come back with a trailer to take the car home.

Re: The Fiero from Hell!

Sucks about the Grand Am. Whoever stole it was probably in for a surprise, and more than likely never did anything with it unless they were a total gear head. If they'd taken it anywhere to get it fixed I'm sure you'd have found out.

At this point the car was relatively driveable, and would keep up with my step dads 2011 Mustang (6 banger), but it wasnt enough, so this is where things get interesting!

That car provided us with endless smiles, the shocked look on peoples faces was incredible every time. I am sure the car was parted out :( it had suspension, rims, etc really is a shame. We had turbo build plans in the making for the next winter. This build is dedicated to my best friend in high school, and his father who can no longer do what he loved to do.

Re: The Fiero from Hell!

yeah thats what he means, you could use the coil bracket and fab up a mount on the fire wall for a dog bone style strut.

When I put the motor back in I plan on using a low mount alternator bracket (in place of PS pump) so that would make a good location for a dog bone mount too. Thanks for the input!
 
Re: The Fiero from Hell!

any way you slice it, as long as you have a bushing on one or both sides it will reduce vibration.
 
Re: The Fiero from Hell!

hell yeah brother! nice build you got goin on...i always wanted a fiero with a 3800 sc.
 


Re: The Fiero from Hell!

Unless that is a hefty cam and you just didn't show pics of the headers you plan to put on, that 3.25 is WAYYYYYYY too small.

Nice job on the ports tho, for first time by hand they look pretty good.

Can't wait to see where you go with this. :th_thumbsup-wink:

BTW if you didn't read this, give it a good look over. May help save you some headaches and give direction.

Re: The Fiero from Hell!

^^That.

i find this fairly doubtful.

And this.

I ran all poly mounts.

Only thing that would give false KR is when something makes contact. My cam busted welds loose and sheered the AC bracket bolts clean off the block. If anything I'd leave it because he has lack of room to begin with...keep that torquey bastage under control. Keep it. What cam did you end up going with? I ran a 3.2" on an XP with stock heads and headers. Granted the Fiero exhaust system is uber short, the manifolds are still a pretty decent restriction.

He's not running poly mounts though he's running a solid metal motor mount. Won't the motor being connected to the body cause vibrations in turn causing KR?
