OK...im finally going to get out thethe junk yard to search for some turbos. What should i keep my eye out for? Which ones came on which cars...like i know that some saabs and volvos had t3's...what did the other cars have besides diamond star? And how can i tell if its bad? Sorry if im confusing right now...im running on 3 hours of sleep for the last 3 days. Thanks.
