I saw this on another forum (http://www.dieseltechtalk.com/forums/showthread.php?70-Stock-turbo-Mod) and figured I would give it a shot since I am sooo close to having EGT's completely controlled. I think this will set me over the edge and I will be able to do whatever I want with the truck.
The thread states that a stock HX35 has only the back 3 cylinders wastegated because of the divider between them. They carry on to say that this design raises EGT's under full boost (wastegate open) conditions. By drilling the wastegate port through to the other side of the exhaust (through the divider), all 6 cylinders are wastegated and provide more flow through the turbo, lowering EGT's. Of course I like to test everything myself so that I can say it worked on my specific truck as well
They said a 3/4" works good but since I have a mill here, I set it all up dead center and drilled it to 15/16". I might go back with a 1" end mill later, still deciding if I should or not. It has to be dead center for it to be that tight as the wastegate valve thing that covers the hole is 1 1/8" diameter, so you don't want it to be off any if you use a big drill bit.
I still need to test it and put the turbo back together, and finish wiring the truck and, yeah it will never run again lol. Maybe friday.
Here's a video I made showing the planning process.
