So far I have blown up two sr20de motors in the past month. One was bad to begin with because it had some blow by and when I got it into boost cylinder 3 rings said bye bye. I bought another motor from the junkyard and after 2 weeks of running that one I spun a bearing. 
Now I found another sr20de out of my buddy's nx2000. Should I go through and replace the bearings or just hope that this one holds up?
