the srt-4's engine is not a 420a as some people say. It is actually based on the pt cruisers engine.
this is a quote about the new srt-4's engine.
(from "Mr. Source"): A turbo model was introduced to the world in 2002 for use in 2003 models. Designed and built in Mexico, refined by Americans (who changed some cooling, reduced boost, and adjusted the PCM), the 2.4 can be tweaked to increase power but was restricted in Mexican vehicles to lower insurance costs. the 2.4 Turbo engine, is Mexican, build in Mexico, engineered by Mexicans and refined by Americans and Germans. They changed some of the cooling, reduced boost, and a different set-up for the PCM. Making some "tweaks" you can gain easly about 10 or 15 % increase in HP. DC restricted it because of insurance. Many of the lessons learned with Super Touring Stratus (Racing Car), were applied to the engine.
I am guessing that virtually no parts are interchangable with ours
