I have access to an 03 2.0 sohc, basicly the whole car, wiring computers and all but the automatic transmission is bad... I want to put the motor in my rt since I locked up the dohc and want to keep the manual transmission. What kind of mess am I gettin myself into and is everything gonna bolt up fine and will the computers plug and play or will I have to use the whole wiring harness. Thanks a **** ton.

 

A lot has changed from the 95-99 to the 2000+. You will need to do the same as the SRT swap, except for the fact that you will be using a non SRT motor so no turbo stuff to worry about. There is quite a lot involved and you would need some adapter mounts and such to make it fit. As far as the transmission, I'm not sure if the 95-99 manual transmission will bolt up or not.

 

mt bolted right up and the motor is in. Will the 2nd gen motor run on the 1st gen ecm?

 

Did you swap the engine harness as well?

From my recollection, you can't run a 2003+ engine in a 95-02 neon without swapping the entire harness over or running a standalone EMS. In 2003 Chrysler went the route of the NGC PCM.
