There is series I, II, and III. The engines withing each Series is the same, some of the accessory mounting is different. Dont bother with Series I, Series II and III can all be used running a 98-02 PCM. Series III needs some changes such as a different TB to work. You can use any of the Fiero Trans's, but theyre not too strong. Can use a Cavalier Getrag F23, or the auto 4T64E thats on the 3800.
Most swaps are done using the 3800SC series II engines 99-02 and the 4T65eHD 4 speed automatic for reliability. I would suggest that you stay away from using the Getrag stick as the Fiero transmissions were not designed to take the type of power that the 3800 puts out. Some swaps are using the F23 stick that is used in Cavaliers, and Cobalt and it is claimed to be stronger but that too is rated for a light duty 170 ft lbs of torque. A step up would be the 3800SC series III (04-07) 4T65eHD but it uses drive by wire controls and its a difficult swap to get working. As a result most series III swaps use the earlier cable operated throttle body and the 03 GTP PCM. Since the series III operated with more boost and made more power, using it with the earlier PCM requires extensive re-programming.

Almost forgot to mention. If you are a die hard stick man the GM F40 6 speed transmission is plenty strong to take a 3800SC swap. Rated to 295 ft lbs of torque it should be reliable. The downside is that it requires some extensive modifications to fit, starting with the replacement of the shifter.

If you buy a 3800 crate engine can you put a supercharger on it or are the internal parts different?
Has anyone done a Cobalt swap? There is even a supercharged Cobalt. In fact there is supposedly one with inboard front brakes. Could you swap the whole drivetrain like they did originally to create the Fiero?

The 3800 N/A uses different pistons and rods. You can put a supercharger on it but you will need what is called a "top swap" ...different intake manifold fuel rail etc. As for the Cobalt, that's an Ecotec engine. Several Ecotec swaps have been done on Fieros but it is an involved process.

"Different pistons and rods" is what I figured. "Different" as in "stronger," right? You 'could' put a supercharger on it, but it might not be any more reliable than a used SC engine, correct?
