There is zero aftermarket support for your car.
Find a tranny with the 3.33 or even the 2.97 final drive ratio. The 3.33 alone makes a world of difference.

=====================
you got the wrong car if modding is your thing -
about the only way to add any "real" horsepower -
would be to add a nitrous kit -
and you MIGHT get two squirts out of it before blowing the engine or trans -

Oh really? And what transmission did you use?
getrag from a Fiero should bolt up
OP you might have more luck with Fiero forums, they have figured out ways to make stuff work

yup - fiero forums. plenty of super/turbocharged engines and many manual swaps. remember - these engines have the same bellhousing pattern as the 60 degree v6's (2.8, 3.1,3.4) and many of those engines came with manual's behind them.
I remember seeing the craigslist and ebay listings for this when it was for sale a few months ago....a Citation with a 4.9L and 4-speed manual...

You can do custom things to it, however, how are you going to make the computer work correctly? The only way would be to have a PCM re-flash from a very knowledgeable tuner. I doubt someone will want to do that, though, except for a lot of money.
Anything can be done, with enough time and enough money. But that doesn't mean it should be done. You can invest $30,000 in a Honda Civic and turn it into a drag car, but you could spend a lot less and buy a 2000 Camaro SS and have a car that's just as fast. I'm all for customizing cars - be it for looks, for performance, for off-road capability, what have you. And I respect the fact that you want to make the car smoke tires. The five-speed swap sounds like an incredible idea. But I don't think the money invested would ever give you the results you want as far as tuning the engine goes. I'd look for something with a 302, 318 or 350 in it, and go to town.
Stand-alone systems have come a long way. Almost dummy-proof. Plug it in, feed it the basics, and it tunes itself. It's amazing, really.
A guy had a driving 91 sts with a getrag from a fiero he was testing for a swap into a mint 91 etc. Than he disappeared off the forum.
These use a standard gm ecu chip burning is easy.

someone who's already done a 5 speed swap should already have plenty of knowledge in this area.ehall said:
I used a 5 speed out of a grand Prix gtp. BOP bell housing
