No I used nitrous on that car until I cracked the head across each valve. I put it a new head on it without changing the cam or flat-tappets.Which when you do that you can cause your flat tappets to not move rip the cam to pieces and bend the valves. (I did that before I went to Wyo-Tech)thats why I had to get a new car because my old car broke the day b4 school.
