Has anyone tried to use the servo from a garrett turbo from a pstroke to operate a 07 cummins 351vgt turbo on my 12 valve. Ok well here is a little background im putting a 97 12 valve in my 03 f-250 pstroke. i would like to use a 351vgt i think it would be good to get me around 500hp. Does anyone know the dimesions of the 351vgt? Is there another way to control the vgt?
