Is the 2.4l dohc 16v engine in a 2004 srt-4 the same engine as a 2004 dodge stratus sedan with a 2.4l dohc 16v?

no the stratus rt is a 3.0 v6

the srt-4 was only in the neon The srt4 engine is very similar to the regular 2.4L. There are some internal differences though. The only difference is the srt-4 components in the motor which can be bought as a rebuild kit if you are yanking a 2.4 from the stratus to drop it in something else, like a neon.
