I did the same as for breaking the nipple off. Mahindra will only sell the complete turbo unit and its approx $400.00. I ordered a real nice aluminum one through
WISH.COM. Cost $13.00 shipped. It is adjustable. Really son of a gun to take off. I had to remove the oil shroud in which wouldn't go back on when re assembled. Before removal I marked the threaded shaft with a sharpie for measurement After removal of waste gate, and yes the metal clips will drive you crazy on threaded end. I had to cut the round holder with a nibbler to match the diameter. I used large washers and drilled for mount. Measure the marked thread and install nut. Reinstall. Takes fabricating but I installed a boost gauge before running engine as to monitor the pressure in case of adjustments. None were required and I have a wonderful 16psi. Also you can hear the boosted turbo from the exhaust, and did make a difference in power. Took about 3 hours and a lot of cussing and a little blood, But that's what being a diesel mechanic is all about. Keep on rollin
