Thanks for the tips, will try craigslist for the bird parts and see how it goes. Am still combing over threads, measuring and reading up. So far the turbo seems to run pretty good. My plan is to get it in as good of running condition as possible then after pulling it out will probably tear it down and have a look inside. Am thinking I can ball hone and ring it, throw some fresh mains in and run it like it is. If I can afford it, will send the head out for service. Sure is cool when that little boost gauge goes up.
