1kwick6, I have the same setup as you do on my GN and am also beginning to shop for a 49. Of course, as the last post said, the JC turbos are slightly more but come highly recommended. I read many positive posts on John Craig turbos. I just priced a couple different 49 setups from him. $745 with a HD actuator, additional $40 for a polished housing, and $775 for one with a ported elbow for the stock dp. Tim
