It really depends how much you want to spend, how much power you want, and how much time you want to put into it.
Rebuilding the 2.8 you have or buying a new 2.8 longblock will cost the least and is easiest to do. When rebuilding several performance enhancing modifications can be done, each adding a little more to the final cost. Supercharging a 2.8 is actually simple, but you must sacrifice the air conditioning (if equipted) to do so. And yes, blowers ain't cheap. Turbos are out there too, but in my opinion the mounting location (on the crossover pipe, usually) is a bad idea, adding more heat to what's already a very warm engine compartment. All in all, you can do a lot with the 2.8, but there are limits.
There are many stock v6 swap options that will give you more power then a stock 2.8 , but most will take increased work and a little more cash to complete. Often a complete computer changeover is needed.
V8 swaps are the most expensive and take the most time. Many carefull modifications are needed to make a V8 Fiero safe and dependable. The pros here are with a smallblock Chevy, the sky's the limit. With enough cash and time, tools and experience, you can in fact have a 350c.i. 600hp, 250mph Fiero. Just don't expect it to be street legal.
Stop and think about what you expect from your Fiero.
How often will you drive it? Will you race it?
Decide what you can afford to spend on it. How much do you have? Will you invest everything in the engine or do other things to the car too?
Evaluate your work area, tools and experience. What can you do now? What can you learn to do? Think about all this, and you'll be one step closer to finding the perfect engine.

i'm going with a 3800 sc series II along with its 4t65e-hd tranny with performance shift out of a '98 grand prix gtp. i've seen some great sites about these engines.
