If I put 10:1 pistons on my car will I still be able to pass smog in california. How much horsepower would you get by putting these in. Also If I plan on going turbo in the future would these pistons work. I know that if I put a turbo in I won't pass smog inspection, it would be taken out when the time comes.n TIA
