A member purchased on of the ebay turbo kits for the Fiero 2.8 and made an install thread. You might want to PM him for more details. //www.fiero.nl/forum/Forum1/HTML/090206.html
A proper setup with exhaust will be worth a lot more than the tail lights are worth..
Probably better off to buy a properly swapped car and be done with it, or get an Ecotec swap together. The 28 year old 2.8 V6 probably won't last too long with boost, and building it up is a waste of money- may as well put a better motor into it
I'm staying original. I'll be Puting a 3.2 on the bottom end to go with a turbo or supercharger. I want to keep the original engine look. Even if it cost me more than a 3.8 swap
What's your budget? A member here has a turbo'ed 2.8 car for sale at a more than fair price --- Francis Truelo of Truelo intake and exhaust fame had his personal car up for sale a couple of months ago. It is fully sorted out and runs like a champ. If you can't find it drop me a pm and I'll get you his contact info.
