stock wastegate difference??
I installed a set of turbos I had sitting around because the ones I had on the car were bad. I did not really inspect them well and after driving the car and getting only 3-4psi of boost, I did some diagnostic work to see why I wasn’t getting full boost. I eventually got to the wastegate and noticed that the WG actuator was holding the wastegate open about half way. So I measured the rod length and compared it to 2 other WG actuators and the lengths were all the same. I then got out an old exhaust housing I have and checked the movement of the wastegate compared to the arm. Here is what I found after I removed the problem turbos from the car…
As you can see from this pic of the wastegates on both housing closed, the arms are at different angles/positions (circled).

So my question is:
Has anyone seen this before?
Is this a different year or make of turbos?
Or has this set been modified or abused?
Here is another pic of the wastegates in the open position (circled)…
