Similarly to this post: http://forums.hybridz.org/topic/113455-internal-wastegate-t3t4-woes/
I am running into a similar issue.
My lever arm was at a funky angle, so I attempted to "clock" the turbo to get the appropriate angle, in addition the inlet was pointing straight out into the inner fender, so I needed to clock the angle to install the piping.
Once it was clocked where I needed it the lever arm is out of reach from the flapper assembly. Its at the correct angle from the flapper, so that its 90 deg. but its about 1" off.
So can I adjust the lever arm (unscrew) so that it reaches or leave it be and figure something else out?
Also, should I be concerned about the housing touching the manifold?
