ive seen sr20's go well beyond 200,000 miles. these engines are very dependable and durable as long as you maintain it well. as long as the cars are running strong, i would not worry about dependability.
that other person would be me!!!!!!!!! i take care of my ride but this past year i have found myself heavy on the foot and she still pulls hard. just take care of it and it will take care of you(plus they really are easy to work on if you ever have problems with em. i have only had to relace the tranny once due to 5th gear pop out)Yosho said:The SR20 is considered to be one of the best 4 bangers ever built.
Here's a link to a fellow that just posted his SR20 has 300k... another person in the thread said their engine has 260k on it.
If the SR20 is properly maintained, it can last a very very long time.
