Thread's for anyone interested in trying something new to come look at, if anyone at all.
The KA24E would be a good idea, for its sound and tunability.
That's honestly all I have. If you want to write something down or to talk about pros and cons, go ahead!

I do not believe that putting an engine that was never used in any GM vehicle in a Fiero is a good idea. That engine is a Nissan product and has zero in common with what GM products have. For instance axles to mate a Nissan transmission to Fiero hubs would have to be custom built from scratch, the shifter would also need to be specially built as will the mounts. Then you'll have powertrain management issue to to cope with and a PCM designed to make it all happen. . I guess anything can be done but the amount of money, time and energy required to do such an odd swap would be prohibitive. ------------------

Agree with Dennis here. For something not done yet go with High Feature V6. At least still GM and I want to learn from your build! LOL!
High feature V6 has forged steel crank and 6 bolt mains, all aluminum and close to 12:1 CR

LT4: 650 hp and torque to match, can get into the 30mpg range, V8 sound, show those Vette guys what a Fiero can do with their engine haha

If I do this (which i might), the hubs would be an issue bot not a large one, shifter is understandable with the concern.
The motor itself will be purely mechanical, what with carburetors and a mechanical fuel pump, to make it easier on the wiring.
All in all, just a normal swap.

I am not a fan of the spinner engines......I like torque.......An interesting newer engine would be the new, all aluminum, 4.3 GM V6 (LV3)...... much lighter than the 2.8 V6, 300 hp and up to 330 Lb/Ft of torque.....And I have heard an older 4.3 in a Fiero and it sounded like a 2.8 on steroids........The only downside is that you would have to use a bellhouse adapter plate.

Some of the available options are other GM 60 degree V6s, including both high value as well as the high feature. Cadillac HT V*s (avoid the pre-87). Cadillac NorthStar . GM LS4.

Please do research on the high feature engine before considering spending the time and money on it as a swap. From my experience it is poorly engineered. The numbers and specs seem good on paper, but it has many inexcusable flaws that in my opinion make it worth its weight in scrap metal. That's it.
