I'd saying starting and idling will be fine, but you could count the abuse time in seconds not miles as you stated! If your going to build a stock engine....fine, if your going to build a performance engine, thats fine too, but you've convinced yourself its a stock engine that just happens to have a turbo on it, and the two aren't compatible with the methods you are trying to use. What kind of bearing clearances did you have on the rods?
