If you are gonna replace the turbo, don't bother sticking with OEM.
They made the turbo too small for the engine, which is great for off-the-line TQ, but is terrible past 2100RPM. Plus, the small turbo equals higher, hotter temps and pressure (Drive pressure) which can hurt the engine in most cases.
Throwing on a used HX35, H1C or HX40 from a Cummins diesel and you will see less drive pressure and more air flow. This will certainly add more serious lungs to the choked down 6.5TD.
