I was making a test run with my truck after adding many goodies (including a turbo-master) and I hit the pedal and pow! lots of hissing from the passenger side (still made 26lbs). Turned and went back and discovered that the expansion plug that came with the kit that goes in the hole where the hardlined wastegate port was blew out. I am supposed to be leaving around 12 tommorrow afternoon for a 3-day ruck show about 3 hrs from here. Any ideas what i can jam in the hole or fill the hole that wont blow out under 32lbs of boost, or where I can get a plug that will fit? Any response is welcomed....the truck is undrivable as the EGT's shoot up to quickly to drive any lenght of time. Any idea what the turbo inlet housing is made of? If steel I could weld it shut.

 

It's aluminum. I suggest drilling and tapping for a pipe plug. If you aren't able to do that, it's amazing what JB Weld will stand up to.

 

Go to hardware store and buy turnbuckle to completely disable wastegate, do search to find correct size or take measurement and rig up your own. (Never fails, just when you're in a rush, stuff usually happens).
