Took about 6 hrs that was 3 of us but really 2 and me picking up the small stuff, The stock intake tube to the turbo had to be cut on the nipples on the inside had to be cut off and the outside ring had to be trimmed off about 1/8 to almost 1/4 " to fit the v clamp to the turbo,wiring harness in front of turbo going up to the grid heater had to be moved on ontop of the water inlet and the tab it was on had to be bent down some, other then that went well stock turbo is hard to get to the pedalstool bolt with new one was easy as pie to install,gave more room all around.
