Re: Converting '04 limited to SRT-6
Take a look at both the SRT6 and NA repair manuals. If you look at the engine electrical diagnostics for both - you can to see all the sensors and wiring differences between the two.
You not going to be able to just swap the ECU in a NA with an ECU from a SRT6.
Lots of sensors and asscociated wiring harness to make, you'll also need to add a pulse module with and all the harness and relays.
I'm willing to bet the farm that you will spend tons of time and lost of $$$ fabricating, trouble shooting and tuning to get your Crossfire running. And you still wont have the suspension or brakes of an SRT6.
Sell your Crossfire and take all that money and time you'll save from the swap headache and buy three used SRT6's. One for you, one for the wife and to strip down, add a roll cage and take to the track.
