530 turbos. We might look into making some with the 2 bolt flange. Mike smith has some nice cast aluminum ones, but he is not ready to sell them yet. I will see if he can get that project going forward, I would rather sell his pipes for those turbo since he has already put the work into it. Mike Smith and Jim Wolf are some of the nicest people in the Industry and I would not not want to cut them out of the loop on the products they have worked hard to provide us. This is a very small market and working together with quality people that offer quality new products is very important to us and makes more since than offering many versions of the same thing and cutting each others throats.
