Joe, you are absolutely correct kind sir. The problem with the 3TC Corolla is indeed the stock carb and exhaust. The research I have done makes me think that I could get more than the standard 25% increase in IT trim. These cars were horribly choked down by the smog gear. Even so, lets say the car produces 50% more power, I think I am still 100-150# too heavy according to the new process. I did find the 80 Crorlla SR-5 has a curb weight of 2187lbs. Its currently specified in ITB at 2310. Im gonna have to run lead to get it legal. Still, no matter what happens with the weight issue, Im going to love running it.
