I am currently attending WyoTech and naturally there are a bunch of diesel students that mainly just drive around and smoke out intersections. However, while attending this school I have learned a lot from the diesel kids about their intake systems and more specifically their turbo setups with a variable vain turbine in the exhaust housing. I was wondering if there was some turbo like that on a newer model Powerstroke or Duramax but that was smaller and more compatible on a Subaru or any 4 cylinder for that matter. I was wondering if anyone had done this, and if so what kind of control module did you use. Any input or discussion would be cool.
