Theory on external wastegates are all the same. They should be in direct flow of the exhaust gases, so they can conrtol the boost better. Same size wastegate in the wrong location can effective turn a 45 into a 38.

You can see the factory location of the where the 38 was suppose to be mounted. I wanted to be able to run pretty low boost at times, so it had to go. The 38 in that location was not going to work for me.

 

You can see in this pic where the new location will be. Its the best placement I can get without running into other issues.

 

Here is what it will look like roughly. I have not had a chance to tack-weld into place, but it gives you an idea.
