Rich, I’m getting 180HP+ out of my 2.3 v4. You could definitly Get more than that if you wanted. My father put in a racing cam, holly carb, racing header and exhaust to name a few. Just those upgrades made a DRAMATIC difference in performance. I’m currently looking into turbo/supercharge options for my engine. I know it sounds like overkill, but I always wanted a HotRod!!
