I have the opportunity to pick up a used MPI stock/475 compound kit local to me. My question is how much clearance is there around the lower turbo? My truck has a ZF6 transmission and the starter had to be moved to the passenger side. I want to make sure there is enough room to clear the turbo and starter. I'm currently running a HE300vg and 6.7 manifold. From most of the pictures I see online it looks like the big turbo sits about where a stock 3rd gen turbo would sit but I haven't found any good pictures of that area to know for sure if it will fit my truck.

Affirm on where you think the 475 sits. It sits basically where the stock used to sit, and the stocker sits directly above it coming off the manifold. The manifold needs to be turned upside down to make it work as well.

Thanks for the info. The side mount would probably work better but these fell into my lap and are a great deal that I would like to grab if they will work for me.
Do either of you have pictures of the lower turbo and clearance? Here are the best pictures I could find with my current HE300vg. Also a picture of the he351 next to the HE300vg. The HE300vg has a much larger exhaust housing, wonder how it compares to the s475 size wise. And looking at my truck it doesn't appear you could mount a turbo much lower than the factory 3rd gen location and still be able to run the intake to the turbo over the motor mount.

from the picture you sent, the 475 would be about 6" back and about 4-5" lower back into the hole where the downpipe goes. I actually recall needing to bend the black AC (evaporator maybe?) cylinder mounted to the firewall out of the way a bit.
