Internal wastegates?
 

i have a TD04(14B), i know how an external wastegate works, but i dont know how an internal wastegate works. i know there are certain weight springs u put in the external one for certain boost levels, but how do you do that on an internal wastegate. thanks

the actuator controls when the wg (flapper) actually opens on an internal wastegate. some of them have threads and are adjustable, so of them aren't but you can bend them to make them shorter to raise the boost, or make them longer by adding to them to lower the boost.

great, thanks a lot

the internal actuator is sealed with the spring inside. do a search or browse back a few pages. some one cut one open and swapped springs and sealed it back. would be a nice hmt tech project.

ya for sure, it would
