Is the Chrysler 420A motor in the Eclipse GS and the Neon the same motor as the Eclipse Spyder GS?
The Chrysler 420A is absolutely NOT the same motor as the Eclipse Spyder GS. When purchasing any bolt on component for the 4g64, the first sanity check you must make is to ask to see if the part is compatible with the Eclipse GS. If it is, 9 times out of 10 it will not fit the Eclipse Spyder. The Chrysler 420A is completely unrelated to the Mitsubishi 2.4L engine.
