Well I have seen heard some stories of dohc's not lasting and blowing up at a young age. I do track days with my totally stock engine and these DOHC engines raced have a reputation of being fragile. If I do blow it up I want to get right back out there with a minimum of down time. I plan on keeping my car for some time its perfect for me and easy to work on. So yeah i guess I'll drive into the ground.
