getting ready to remove the butterfly in the housing, i could only find steel plugs in the local advance auto parts, no one else had them, itm just trying to make sure there not going to melt and blow hot exhaust under my hood.

 

They wont melt. the turbo cant get hot enough to melt steel.

 

would not worry about steel in turbo,think about alloy pistons.

 

To clarify what you said if i am right for everybody. The pistons will melt before the steel in the turbo. That reminds me of a friend who had the idi 7.3 diesel he cranked his injector pump up so much the pistons literally melted no joke.

 

what size plugs does it take
