wastgate swap acheived : Project YardDog
Here is the T25 that. I will be using in my setup.

I have done my research and found that the 4G64 will overspool the turbine due to its higher displacement and c/r . As well as the lateness of the stock wastegate at 15 psi.
Opening the gate at boost is too late to check the higher pressure/flow of the 4G64 if pushed . Lets be honest what's the fun in a boosted g you can't push. I figure if i get a lower psi actuator the wastegate will open sooner thus slowing the spool of the turbo. Here's the thing tho the T25 made 14psi stock I'm looking to maintain around 10 so I am really not worried about the slowed spool. Research tells me the T25/4G64 will reach 15psi around 3k with this open late mod I am sure I can make 10 at 3500 so here's my fix

This is a MUCH smaller IHI VF turbo I had laying around I don't know what its wastegate opens at psi wise but the arm is significantly easier to pull. So I put 2 and 2 together. Literally :-)

a hammer nail screw bolt socket and wire cutters .... I made this :-)

Well it opens and closes the gate properly and its good and tight but I made it more to see if I could with what I had and get an idea of what I needed to make than planning on using it in the build.
SO ITS OFFICIAL WASTEGATES CAN BE SWAPPED THE QUESTION IS ARE YOU BROKE ENOUGH TO NEED TO? AND CREATIVE ENOUGH TO PULL IT OFF?
