all of Kens turbos are great , and well thought out. there is more to a B1 , B2 BB and B52 then just using a S300 or such, the wheels are custom matched for each application. and I don't get free stuff for saying this either , I would pay double for the right turbo then use a free part that is not exactly what is needed. Ken is not always the cheapest , but if cheep is what you want that is exactly what you will get. Ken will work to get you a turbo sized to your needs , not just what he has in a box ready to ship.
