thinking of a eclipse gs-t

550whp and it couldnt take the beating? Interesting, I've made well beyond that for many years with lots of different dsms and have had no problems. You might have had some issues. I wouldnt go as far as to say that all 4G63's cant take that pounding. It's been a proven powerplant for quite sometime now.

500hp is about the mark where the 4g63 starts to need some internal upgrades
