SRT4 is a faster car than a crossfire. I think it would even do better on the track given the right driver and a 03 equipped w/ a factory quaife limited slip diff. Chips aren't a thing for us / jap cars. They are a german thing. Bump up injector size, increase boost, throw in a fuel controller and tune it out. Mopar has some factory options, different ecu, injectors, increased boost. Does all the dirty work for you.
There are also aftermarket turbo options, which will push that 2.4 to no end. I've already seen numbers over 450 on the stock motor.
As for a daily driver, its a neon. If you can get past the looks its a good car. If you can drive it like a normal person, you will get great gas mileage.
