High mileage n20s

[nickn20]

Hey guys, I have a 2014 bmw x1 with the n20 engine. I am tuned with a jb4 and I have about 215k miles on the car. I was just wondering if anyone else has reached the 200k mile marker on their n20. If so, what can I do to make the car last as long as possible. I want to replace the engine when I need to but I would rather have the original engine last as long as possible.
