Replace main bearings or not?

[Race94]

I just bought a low mileage JDM 6-bolt block, the bearings are in good condition but i'm going to swap it into my 2g and it's out now, should i replace the main bearings?
Any cases of bad ain bearings on dsm's??

Thanks

while youve got it out you had might as well do it , and while youre at go ahead and do the rings to. its a awhole lot easeir when its not in the car. that way you are starting out with a "brand new" motor so to speak. thats just my $.02 good luck

While you've got the chance you may as well replace them, at best they are probably 12 years old unless they were replaced before. I'd do it, especially if you can get a good deal on them!!

why WOULDN'T you replace them?! Bearings are like $50 - $75 and I'd do a clean up hone at least and new rings. You're basically starting with a fresh motor then. I'd even consider polishing the crank while it's all apart.

and if you do the bearing take the crank to a machine shop(or you can do it yourself) and have then mic it. had a friends engine eat itself cause the crank was worn and bearing didnt quite fit right.
