ive heard a lot of people that refuse to use a turned crank, once it has any form of damage you just find another one. any thoughts

It really depends upon the extent of the damage. I've reused them in low hp applications, and put in new ones in higher horsepower applications. The stock crank isn't that bad and a micropolish or putting a small cut on the journals and using the proper bearings will be fine.

Wouldn't one want to figure out why a motor spun bearings in the first place?

I thought it was too risky to just get the crank polished/cut and throw in the proper bearings. Maybe it was just improper install which caused the damage or something else? I'm sure it would have been fine with getting the crank polished but it would have been too much money to fix it for what a 7 bolt was worth to me.

You guys are hitting a three month old thread, I don't think he's got that car anymore. He's got a 3G now, better know as an Evo.

Gah fail on my part sorry. That's what i get for not looking at the op's last post date. May this thread rest in piece lol.

Well the discovery behind the failure is always step one. Was it contamination? Stretched rod bolts? Installation error? something else? From there you would make appropriate decisions as what can and cannot be reused.
