But, I plan to go with a very similar/identical setup myself. Should be a great turbo if there are no bugs in Chip's setup and he can get it to bolt up well. Already, his GMS 550 ballbearing setup is looking extremely attractive for those with more modest goals and seeking minimal lag. But, as with all turbo kits judgement can't be made until a few are setup and the owner/installers report back. I'm optimistic, and now that Chip has a better turbo parts supplier we will hopefully see some great turbos and customer service out if his shop next year.
