A larger turbocharger inlet manifold was added to help lower intake and exhaust temperatures while improving responsiveness from the Garrett GT3788VA variable-vane turbocharger (VVT). The Bosch solenoid-style fuel injectors were updated to a 7-hole nozzle that sprayed fuel directly onto the new fast-heat glow plugs when cold to provide faster start up. The reliable Bosch CP3 injection pump would still be used with an improved rail pressure of 26,000 PSI. One of the main components to the increase in power was upgrades to the common-rail fuel system. The forged steel connecting rods were also reinforced to handle the increased horsepower and torque. ![]() ![]() The cast-aluminum pistons were revised to lower the compression ratio.
