Generally speaking, an LPT is a standard turbo with smaller impellors. Nothing else is different (other than the ECU controlling it). The normal failure for a turbo is bearing failure. This happens prematurely when the heat of the turbo bakes the bearings. Most serious turbo installations have coolant lines running to cool them. They all have oil lines for the bearings. If you maintain your cooling system (flush and change every two years) and change the oil on a regular basis, the turbo can last a very long time. Synthetic oil helps, not only due to better lubrication, but because it runs at a lower temperature, too (averages 15ƒF cooler). Heat is the enemy.
