my buddy has an 88 N/A with cats removed and a better breating intake system. We were driving around last night and pulled up behind a 3rd gen RX7 and we sort of raced. The guy took off and then we gave chase. All i saw on the 3rd gen was an exhaust system. The 3rd gen was pulling away, but not as hard as i thought it would. He then let up and let us catch up to him at about 100 KPH. We were then side by side and my friend took off. Then he took off and passed us and had a good 5-6 cars on us at 200 KPH. The 3rd gen looked like a turbo model because of the rims, but by the way he was pulling on us leads me to believe it wasn't. Is there a better way of determing just by looks if it's a turbo model???
