You can take my post at 50%, because I don't know too much about the starters on these cars. But...It could be possible that the starter needs to be shimmed (if we have shimable starters) or...possibly a problem with the flywheel. Again, don't take my post at full weight.
(I'm basing this all on another platform car, don't know if it applies to the duratech or not)
And congrats on getting your 3L going!
