spun bearing - pictures

what would made this happen? Its a fully stock 94 eclipse turbo, but higher turbo pressure (about 20psi at that time only heheheh)

it just happend 500miles after a head rebuilding, during a fuel pump test, driving it 3 times at 7500rpms. 5 minutes later i got a ticking sound that seemed like lifters (a brand new full set of johnsons). My car had not any, i mean *any* ticking sound before that test. Yes i was stuppid to drive it for more about 50miles when the noise got so high i was hoping to not lose my engine. God dam***! in so stupid...

Bad oil? Too much turbo pressure (4g63 can handle about 450hps stock, doesnt it?)? crankshaft bearings with too much wear (out of spec)? BAD LUCK? heheh. Will i lose the crankshaft?

nice, im gonna do a little research about it.

one last question: how much did that cryotreat on your crank cost you?

Regards!

Sorry I cant give you an exact price but I know generally its priced by the weight of the object, like every lb is so much amount. I dont know, but the guy who built my engine included cryotreating the internals in his services so I kind of got off on that one.
You also have to see if they have cryotreating specialist in your area.
I have a friend with a 600 something whp single turbo supra and hes on stock cryotreated internals and his engines holding up to 43lbs of boost ( partially also because supras are built for high power anyway )
and the guy who built my engine his gst strokers engines internals are cryoed and one day I was riding with him he was having serious problems with his car because his logger showed like over 2hundred counts of knock which i thought was a logger error so we used a different one and turned down the boost and was still getting ridiculous counts and his internals were taking it with no problem. ( but he's forged, and still of course that wouldnt have lasted long ) But i mean my point is its a good thing to do .
Hopefully i will have a longer lasting motor with this treatment, and reduced chances of spinning a bearing or something since I havent really gotten to break in this motor hard yet.

I also plan on cryotreating my rotors, clutch and flywheel upgrades, and perhaps my turbo ( whenever I get a new one )

nice man, thanks for saying! It really seams like a good option...

Good luck "for us" hehe...
