Motor
Since anything worth doing, is worth overdoing we went to work on the motor while we wait for the inspiration to percolate, and the funds to catch-up.
We rebuilt the stock turbo, modifying it with the advice of Paul at High Tech Turbo, replacing the compressor housing with a H1E Holset capable of pushing a little more air. The turbo is now a H1C/E hybrid.
We got with Mark from PDR diesel for a set of their "Prince of Darkness" injectors to add more fuel.
A modified fuel pin, higher rpm governor spring, and new valve springs were also added.
Since the turbo compressor housing is so much larger that stock, the turbo will no longer work in the stock location, so the stock manifold was flipped upside down, and the turbo oiling was modified to accommodate the "high mount" turbo.
The air is fed to the turbo through 4” stainless tube, and a K&N filter.
Since we are adding a charge air cooler (intercooler) from a Freightliner MT35 chassis that was running a 4BTAA, we had to build our own intake manifold to clear the turbo intake (so much for hood clearance).
