I need to know what companys make strong motor mounts? What kind of hp can they take? I have also heard about engine dampers? are they worth it? I could see why they are but if your motors doesn't move then I don't see the point of having one. I am building an engine that should be producing around 300whp. If my 200 hp engine kept breaking stock parts. I need advice on what good upgrades are out there. I have thought about cryo-treating the tranny. Some people say its worth the $450. Some disagree. Please give me your opinions.
