I have done dozens of CM871 turbo's and it ALWAYS goes to the half a hole position on all of them. I have seen a few that did not do this form new, and they were bad from new.


On the newer CM2250 and 2350 engines, and their turbo's, I cannot tell you for sure yet. I have not had one apart yet, but i do know that The new turbo will also usually come with a plastic piece that will show you travel range.
