Ok so my 02 rsx is getting up there in the miles department,it still runs good and I'm pretty sure I still can get another 100,000 miles from it. It's currently at 191. While going on those long drive I started to think to my self, if the motor goes out I can't scrap the car, I like it too much to just get rid of it. My question is what engine fits the base rsx that will give it more power but with little to no modification to the frame as possible?
