high milage

[auh]

How well do these engines hold up stock if they've been well maintained after 200k?

[574-240sx]

Yeah they hold up fine if properly maintained. My last 240 had 198k on it and still runs to this day. There are many 200K+ KAs on the board. If those miles are from the midwest I would worry about rust.

Very well I think. I just hit 190k on my daily driver S13 last week. Make sure that it has been taken care of and it will run like a champ. I drive my S13 REALLY hard too. I use Durablend oil, half synthetic half organic dino oil. I change my O2 sensor on the exhaust every 2 years to keep my fuel mileage good (a steady 25-28 mpg is what I get). The best thing I'ver ever done though was ask my mechanic to replace the rear seals when he put in another OEM clutch (it's all stock, no need for a powerful exspensive clutch), the new seals cured a minor oil leak. This is my second S13, the other had 150k miles when I sold it, and I bought this one with 173k miles! Everything will fall apart around the engine before it breaks

My KA24E is running with 223K miles on it. No rebuilding done yet. So I guess it's still holding together.
