I have a 1994 k3500 , an right now I have a Borg Warner turbo but I'm looking to swap to a. PowerMax GVT turbo off a 6.0 f-250. I know that will allow meto to build boost at a stand still. But I'm concerned about building to much boost. So any help would be greatly appreciated.

 

Haven't heard of anyone using that turbo yet?
Having to deal with creating your own electro mechanical linkage for the VGT will make this more trouble than it's worth I would think.

Others have been trying to work that out with other VGT turbo's but I have not yet heard what works that is not totally dependant on an operator like a variable resistor controlling a stepper motor ect-nothing computer controlled has been developed yet that I know of.

A T3 flanged holset HX40 is the most common turbo swap followed by the direct bolt on ATT turbo.

 

I'm mainly wanting a turbo that will build fast boost an whistle
