I was racing a Mazda 6 in my N/A 5 speed on the way home, and as soon as i hit 105 the car made a clunk noise and started to shake like hell. So I pulled over and tried to look in the engine but it was slightly raining and pitch black. It accelerates really slow now. In 2nd gear it takes about 3 seconds to go from 3k rpm to 4k rpm. I'm thinkin i blew a piston but im not sure. Please help. :1zhelp:
