I ignored his request for 4 bolt turbos so he didn't have to swap DP's because it's a stupid reason. He will probably be able to trade straight up for some 5 bolts. The 4 bolts tend to have a higher resale value because they were the only ones to always be made in the USA. The 5 bolts 3" DP's were outsourced for a time. Even if he was to sell the 4 bolts and buy 5 bolts he wont lose much of anything. In fact if he bought turbos from SZ I bet you Greg would be willing to make a very fair deal to get him the correct DPs.
