GT4502V for Detroit Series 60 14.0L: The DDEC V VGT Turbo

The Series 60 14L was the last generation of the classic Detroit Series 60 family, offering more displacement and power than the 12.7L. The GT4502V is a Garrett VGT turbo — unlike the Series 60 12.7L which uses BorgWarner K31 and S400 turbos, the 14L uses a Garrett unit with an electronic VGT actuator.

Installation and Care

Find out why the old turbo failed before installing the new one. Oil starvation or contaminated oil will destroy the replacement the same way.
Change the engine oil and filter. Flush or replace the oil feed line.
Replace the exhaust manifold and oil drain gaskets. Prime the turbo with clean oil before startup.
Connect the speed sensor and verify VGT operation through the DDEC V ECM before loading the engine.
