First off, I'm asking for a friend of mine. He has an 04 Duramax that he was thinking about putting a Borg Warner S475 T6 turbo. I wasn't sure what all he would need to put it on his truck, so I told him I would look into it. Have any of you guys done a similar swap or maybe have a link to someone who has ? Thanks ahead of time

 

Way too big, he would need dual fuelers to light that thing off, custom turbo pedistal, and Im not even sure it would fit in the valley to begin with. Is his truck an LB7 or LLY, 04.5 and later is LLY which ahs a variable vane turbo which opens up another can of worms.
