The Challenge:  The biggest challenge to putting the 3800 Supercharged engine in the Fiero is the motor mounts.  The original Fiero's had a dog bone type engine mount for the upper mounts but that won't work with this larger engine.  If we leave the bone off it will make the engine wobble back and forth jerking the passengers whenever I gave any power to the throttle.  I've read a few posts online that say you can weld a few working $20 Ford motor mounts onto the frame of the Fiero and make the engine stable.  There are a few other challenges like making the exhaust manifold seal and fit into that small space.  Either way I have my work cut out for me, literally lol.  Essentially when it's done it will run a 3800 Series II supercharged engine and transmissionThe picture when it's all completed will look something like this:

Why a Pontiac Fiero?
My friends ask me this question all the time, my only reply I have for them is that I've got something to prove.  "Some things get meaner as they get older!" >:3 When completed this will look exactly like a stock Fiero SE, they won't realize the monster under the hood until it's too late.  The only modification that would be better than this would be an extreme modification done by professional mechanics who are willing to make cuts to the frame to fit an 8 cylinder engine like the 4.6 Cadillac Northstar, or the LS-4 Engine.

The Finished Project should look like exactly like this:

A Little Luck:  While saving my money for the parts to fix the car, I ran across someone willing to sell me an engine that just might replace the one that is in the Fiero now.  His car was involved in a traffic accident and the rear of the car was totaled, however the engine and transmission are just fine.  It's a 3800 Supercharged engine!  He was willing to sell it to me with the transmission for a decent price too!  The price he was asking was just a little higher than what I would pay just replacing the parts on my car, considering all the gaskets that would need to be replaced.  The price was still too good to resist for an easy mod.  However, there are a few problems with putting this modded engine into the Fiero frame though.

This...truly...is a thing of beauty.
Problem Investigation:  I took the Fiero to a master mechanic and we have deduced that the knock in the engine is being caused by a broken cam bearing that is blocking oil flow to the top half of the engine.  It's not an easy job to replace because the Fiero's design makes you have to take the entire engine out of the bottom of the car in order to replace the part.  The engine in a Fiero is in the rear of the car, behind the driver and passenger but also in front of the rear tire, making the Fiero a Mid-Engine rear wheel drive car.  The front of the car under the hood is reserved for the radiator, fans, spare tire, jack, and a place to slide in the tinted moon roof glass at the top of the car under the hood making it a mock "T" top.  The official trunk of the car is located in the rear of the car just behind the engine and rear tires.

The Project:  Performance Modding for a 1987 Pontiac Fiero 2M6.  I bought this car 2 years ago and it came stock with a 2.8L, 6 cylinder engine.

The Problem:  About 2 months ago, there was a knocking sound in the engine that slowly got louder.  The engine ran just fine, but the knock needed investigation.  There are also some various cosmetic changes that are needed such as an addition of a racing spoiler which needs painting, as well as the whole car needing a paint job.
