Intake hard pipe clipped for the flange, pipe turned on the lathe with retaining bump for spigot and welded in place. The ø2.5" 90° silicone hose...
Thermostat housing had a blanking plug in one position; Now modified for stock DT bulb to drive the temp gage. [ATTACH] [ATTACH]
Transmission cooler mounted on frame cross member under cab. [ATTACH]
About 2 days print time, split into halves to fit on the printer bed.
Nice thing is the model is fully parametric and stable, so all that is 5 min worth of mouse work: [ATTACH] [ATTACH] [ATTACH]

More detail on what isn't modeled, and yet is in the way: Oil dipstick tube and frame-wastegate clearance. [ATTACH] [ATTACH]
So there's good reason for printing these test items out. Seems like a brilliant design at 6AM, 100 miles away from the truck- and slightly less...
Since the intake is going to exit downwards to get to the intercooler, a straight shot between frame rail and engine while avoiding the starter...
So the turbo foot is correct, the manifold studs line up and the manifold generally fits. Block side plates stick out 1.5", more than expected so...
Got the printed manifolds in place for a fit check: [ATTACH] [ATTACH] [ATTACH]
48 hours and 37 minutes later we have two halves of the manifold ready. They fit properly on my spare head which is always a nice thing to see....
A friend of mine suggested to do a compound turbo. Hmmm [ATTACH]
