What engine lasts longer?

[Ryeguy475]

I own a isx 871 and it’s been a money pit, it did make it to 534k miles/ 22k hours before I had to inframe it. Before that it was vgt turbo replace and emissions problems. After the in frame I had (still have) a vibration that appears when engine is under load. Broke crankshaft. I can’t say if any of these problems were caused by poor tuning when it was d-leted or what. It has been well maintained though, oil & all filters changed every 10k Miles. (Its always done local work) . A good friend of mine has a 2007 14l series 60, he had the egr deleted and put a single stage turbo on it & he loves it. I’ve been thinking about taking my 871 out & transplanting a N14 in lol
