So I've got a spare bottom end that I'm getting ready to put in my 91 Si and I'm trying to figure out what I need to replace so I can go ahead and get the parts before I take apart the bottom end. I'm planning to put new rings in it and also will check the rod and main bearing clearances and replace those as needed. I'm also going to do the clutch, pressure plate, throwout bearing and pilot bearing while it's apart. What else should I plan on replacing? Thrust washers? Which seals are normally done while it's apart? Once I get it together I don't want to pull it out again for a while so any advice is greatly appreciated!
