This question is for the Ultimate turbo Z's out there? How much do you drive your Z's and how hard do you drive them. I'll race anytime Especially since I live in GM Suburbia where there are lots of v8 iron monsters. I daily drive it all summer and I'm not afraid to push the envelope at the drop of a hat. I'd like to know how reliable your engines are and how long do you expect them to last? 400+ hp is a lot of power for our little sixes to last very long under agressive driving and racing.
