A buddy of mine picked up this freshly rebuilt turbo today and I was wondering if anyone could tell me anything about it. He was asking me but I know little about Turbos. The main thing he was asking about was the stamp plate on it said CAT. I'm assuming it came off of a tractor or dozer or something. It is HUGE. Will it work on a car? If not no biggie. He really dont want it and if it would work on a car I can get it dirt cheap for my 5.0 project!! It is very clean. How about a value?? I will get the info on the tag tomorrow. Thanks guys.
