Most KAs last probelm free between 150k-250k miles. They will need regular maintenance, but you shouldn't have any major problems. Also, as far as the not putting a turbo on, you can put a turbo on any car with the right preparation, its when people don't do the job right, or do more than can be handled that you run into problems. Not that I am suggesting just throwing a turbo onto a 150k engine, but thats my point. People do that, and then wonder why they have problems when they kick the boost up to 1 bar. It doesn't make sense to me. Enjoy your day!
