I'd say 200-250k is a realistic number for most people. I've seen a couple 200k+ mile N54's, all of them stock with no mods. Don't expect to see many heavily modified n54 going past 200k. They are not reliable at all once you start running more than double the original hp. These engines are not worth rebuilding since you can find low mile motors for 1500-2000.
Obviously if you're shooting for 700+ hp, rebuilding would be a good idea. |

215k on my 2007. Stock, no mods. Once I changed all the oil seals, including the rear main, it's been nearly flawless. Honestly, it's quite a good motor!
Just did an oil analysis on a 7500 mile run of T6 with 95% city driving at less than 25 mph and sub-zero starts. It had 2% fuel dilution but otherwise looked pretty good. Iron was 29 ppm. Not quite Toyota levels of wear, but still really strong. Aside from the things we know about these motors - injectors, water pumps, coils - they're pretty stout. |
