i'd imagine the turbo would be in good working condition since they are backing there engines with a 3 year warranty.
there are quite a number of turbo kits available but to tell you the truth i don't know which one is better. if i had a trubod engine and was looking into getting a turbo kit i would know more.
www.suprastore.com has turbo kits
instead of buying a whole new turbo you can get your factory one upgraded
