Until you can bring this car to my garage and let me look at it I am going to say BS on it having an 05 SRT-4 swap. What tranny is he using? If he using the SRT tranny how much of the frame did he notch to make it fit and who built the custom axles he would need? What standalone system is he using to run this motor? If he is not running a standalone system how did he go about wiring the SRT electronics up? If he bought to motor off ebay then I am guessing he did not get the body harness which he needs to splice into the 1st gen harness. I am guessing at the most he has a turbo 2.4 swap with an srt valve cover. If you want me to put holes in your story anymore I would be glad to. If you want me to tell you how to put the engine in your car I would be glad to. I can ask over a dozen more questions that could prove this is not an SRT swapped 1st gen.
If you have any questions on the 1st gen neon go ahead and ask, I do have the answer. PM and we will set up a time to validate your claim of an 05 swapped 1st gen, I am sure you won't do that though.
