You can buy a cast log manifold on ebay for cheap these days. get an intercooler kit from ebay too. for turbo wise, get a name brand one new or good condition one. you can get used tial 35mm wastegate for cheap too. if you want, PM me and i can set you up with a price range. dont worry about milage. do a leak down test and it'll let you know if your motor is healthy enough for boost.
