Whatever your wallet can make go in there. Personally? I've replaced the stock 2.5, done a clutch on a 2.8, and even welded in a 500 cube big block out of a 72 eldorado in the back of a fiero. Granted, I had to rip out the sub-frame, trunk, and a few other things, and (beer, Pizza, a stupid side bet, and too much cash aside) it really wasnt done quite right because it was more of a joke than anything else, but it did fit...
Side note, if your putting in a 500, be sure to add some reinforcement to the floor of the fiero, as well as the firewall, otherwise you'll just end up ripping the back end of the car off from the torque, and having to tow home two halves.
But it was pretty cool...
Mine is currently getting a 3800 supercharged out of a Grand Prix GTP
I have done 3 Small block chev conversions
And there are many of the new overhead cam GM motor out there
But my favorite is the Cadillac Northstar
