heres what I know.

Talons/Eclipses came with both turbo and nonturbo 4g63 2.0L 16v dohc mitsy engines

I believe maybe the 2nd gen non turbo ones came with the 420A engine. Some of them did at least..

The 2.0 that was in the neons is most likely a dodge engine because the block is very similar to the 2.2/2.5s. I dont know if thats the 420a or not.

I believe the 2.4s are spawn of the 2.0.. probably just stroked like maurice said.
