[Vwdiesel] ECO diesel intake size?

[Shawn Wright]

I've never seen an ECO diesel up close, but have a K14 turbo from one on 
my Westy. It has a much smaller turbo intake than the regular turbos, so I 
was wondering what the rest of the plumbing looks like. ETKA shows the 
same airbox, but the hose to the turbo is different. How much smaller is the 
ECO one?

I'm trying to get a feel for what is the minimum acceptable intake hose 
diameter for a 1.6TD running up to 15psi of boost. I may need to run across 
the (Vanagon) engine bay, which means 4-6' of tubing before the airbox. I 
was hoping to use 2" rigid PVC to save space.
