All the VNT 15s (and the KKK turbo used on the 2004+ PD cars... I think it's a KP39?) have the turbo integrated with the exhaust housing.

And 2x... if a lill 1.9 can push the limits of one of these, putting it on a 3.0 would be like running a mile breathing through a soda straw. I feel bad enough running mine at 17.5 psi!
