depending on the care from what i have seen around here 100,000 to 200,000 is not uncommon.(properlymaintained of course) your driving personality makes a difference in the lifetime though.

its very common to see 240sx's with over 200k on them. I have heard horror stories of detonation/pistons flying all over the place but this is in turboed and/or abused hard driven 240s. Guess you dont slap a turbo on an engine not ment for it.
"The path of the righteous man is beset on all sides by the inequities of the selfish and the tyranny of evil men. Blessed is he who, in the name of charity and good will, shepherds the weak through the valley of the darkness. For he is truly his brother's keeper and the finder of lost children. And I will strike down upon thee with great vengeance and furious anger those who attempt to poison and destroy my brothers. And you will know I am the Lord when I lay my vengeance upon you."

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!

A note on racing the KA in autocrosses. I would suggest getting a baffled oil-pan that holds 5-qt.s. I have heard of most KAs dying on the auto-x tracks. This is because of the higher revving and oil starvation that occures when you corner. Imagine what happens when you are topping 5k coming out of a corner and all the oil in your pan is crammed to one side. You starve the motor of oil for a few seconds... in that few seconds the motor the motor has turned over 170 times. All it takes is for a bearing to dry up and seize which generally ends up throwing the rod through the block. I have known of 3 KA24DEs blowing up at auto-x events just in the local area alone. 2/3 where very experienced drivers that kept their 240s in very very good condition.
