So whats the deal? If I want to go aftermarket I need another exhaust manifold OR a adaptor plate for the stock one? What do most people run the "t" series from garret? Do they make adaptors for all the common turbo companys? Does each company use there own adaptor? Whats the more common lower priced turbos people use on the supras? What is the difference in flow vs stock the CT 26 seens decent
