1996 Plymouth Neon Sport DOHC?

I have two 97 dohc 2 door neon's. They have 150 horse power. I have a mopar performance computer in one and I am swapping in a 2.4L in the other this weekend. I will tell you how it runs when its done. I need to order a few small parts so it still won't be running this weekend but hopeful the end of next week.
